Here is an article by a Canadian Astrophysicist who does not accept Big Bang:
Big Bang Cosmology Meets an Astronomical Death

Published by: 21 st Century, Science and Technology, P.O. Box, 17285, Washington, D.C. 20041. Vol. 3, No. 2 Spring 1990, P. 52-59.Caption for Crab Nebula.
More and more astronomical evidence points to the absurdity of the theory that the universe started with a Big Bang. A Canadian Astrophysicist presents this evidence and explains how the cosmic redshift is caused by gaseous matter in space, not by the Doppler effect.
Interstellar matter, seen here in the Crab Nebula in Taurus, has its counterpart on a larger scale in the rarefied intergalactic medium. The intergalactic medium was first shown to exist in the 1970s. It is impossible, the author says, for the light we see from distant galaxies not to interact with this medium as it passes through it.1 --- Introduction.
We are all so accustomed to reading that the universe "began" once a time in the Big Bang that most people no longer think it necessary to question or scrutinize it. A detailed analysis of the Big Bang theory, however, leads to consequences and implications that are irrational, or are contradicted by astrophysical observations, including important ones.
At the same time, one of the pillars of the model, the all important cosmic redshift- the shifting of spectral lines toward the red end of the spectrum, in proportion to the distance of the source from us- can be explained without invoking the Doppler velocity interpretation (1) so dear to Big Bang theorists. The redshift is explained instead by taking the intergalactic medium into account, and correcting our understanding of how light interacts with such a medium on its way to the observer. Two different theoretical approaches, semi classical electrodynamics and quantum electrodynamics, have shown that all interactions or collisions of electrodynamics waves (photons) with atoms are inelastic; that is, the photons lose a very small part of their energy as a result of the interaction. Hence, the greater the depth of the intergalactic medium through which a galaxy's light must pass toward the low-energy end of the spectrum - that is, toward the red.
These considerations eliminate the limit on the size of the universe imposed by the Big Bang theory. Indeed one can say that the universe is unlimited in the sense that no experiment has proven otherwise. Observations of our unlimited universe show it to be compatible with the principle (known as a Perfect Cosmological Principle) that the universe must look the same to any observer who moves with the cosmological fluid, regardless of his position in time or space. Furthermore we can see that an unlimited size of the universe is required when the phenomenon of star aberration is considered.2 --- The Big Bang Universe.
It is widely believed among scientists that the universe was created from an extremely dense concentration of material. The original expansion of this material is described as the Big Bang. Although the primeval soup is thought to have originated at zero volume, quantum physics considerations require that it could not be described before its diameter in centimeter reached about 10 -33 (that is, 1-billion-trillion-trillionth cm). This means that the universe, then expanding at about the speed of light, was about 10 -43 second old.
After that instant, according to the Big Bang theory, the universe kept expanding and became many billions of billions of times (on the order of 10 20 times) larger and older, until it reached the size of an electron that has a radius of approximately 10 -13 cm, when the universe was 10 -23 second old. During the following 15 billion years, according to the theory, the universe expanded to a radius of 15 billion light-years to the size it is claimed today. (A light-year, the distance traversed by light in a vacuum in one year, is 9.5 ´ 10 12 kilometers.)
The author (center) with the organizers of the Feb. 1989 Plasma Universe conference in La Jolla, Calif., Nobel laureate Hannes Alfvén (right) and Anthony Peratt of Los Alamos National Laboratory (left).These are the dimensions and time scale required by the Big bang model, a model that has certainly not been accepted by all scientists because it leads to insurmountable difficulties. Prominent scientists like R. L. Millikan and Edwin Hubble thought that the Big Bang model created more problems for cosmology than it solved, and that photon energy loss was a simpler and "less irrational" explanation of the redshift than its interpretation as a Doppler effect caused by recessional velocity, in keeping with the Big Bang (Reber 1989; Hubble 1937).
In more recent years, Nobel Laureate Hannes Alfvén, and other students of astrophysical plasma, have challenged the Big Bang with an alternative conception called Plasma Universe. In this cosmology, the universe has always existed and has never been concentrated in a point; galaxies and clusters of galaxies are shaped not only by gravity, but by electrical and magnetic fields over longer times that available in the Big Bang model (Peratt 1988, 1989; Bostick 1989).
From its birth in the 1930s, the Big Bang theory has been a subject of Controversy (Reber 1989, Cherry 1989). Indeed, our view of the universe must always be open to consideration and reconsideration.
This article will demonstrate that the big bang model is physically unacceptable, because it is incompatible with important observations. It is not even acceptable philosophically, since it implies that time began to exist at a supposed instant of creation. It is therefore impossible to speak of a cause of the Big Bang (Maddox 1989). Science, however, is dedicated to the discovery of the causes of observed phenomena; the Big Bang model thus leads to the rejection of the principle of causality that is fundamental in philosophy as well as in physics. It is actually a creationist theory that differs from other creationisms (for example, one that claims creation took place about 4000 B.C.) only in the number of years since creation. According to the Big Bang model, creation occurred between 10 and 20 billion years ago.3 --- Defective Evidence.
Support for the Big Bang theory has been built upon three main kinds of evidence:
First, the Big Bang assumes that the observable universe is expanding. Proof of this is offered by interpreting the redshifts of remote galaxies and many other systems as Doppler shifts. Hence these redshifts "prove" that these systems are all flying away from each other.
Second, the Big bang theory predicts the cosmic abundance of some light elements like helium-4, deuterium, and lithium-7. The available evidence of cosmic abundances is said to confirm the predictions.
Third, Alpher, Bethe, and Gamow in 1948 used the Big bang theory to predict the existence of a low temperature background radiation throughout the universe at 25 K as a relic of the initial Big Bang explosion. A background radiation at a temperature of about 3 K (emitting radiation 5000 times less intense, see Planck's law) has indeed been discovered (2) , and is being interpreted as the predicted relic.
Finally, in addition to these kind of evidence, it is claimed that the Big bang hypothesis agrees with Einstein's theory of relativity.
The support afforded by the Big bang model by these four arguments is, however, only apparent and does not withstand a serious detailed analysis. In fact, the observational evidence from astrophysics is more in keeping with the model suggested by this author of an unlimited universe. Here, in brief, is the evidence from astrophysics:The Redshift.
A large number of redshift observations cannot be explained by the Doppler theory. Astronomer Halton Arp's 1987 book Quasars, Redshifts and Controversies provides an extensive review of them, as does a lengthy 1989 review article by the Indian astrophysicist J. V. Narlikar. A catalogue of 780 references to redshift observations inexplicable by the Doppler effect was published in 1981 by K. J. Reboul under the title, "Untrivial Redshifts: A Bibliographical Catalogue." Many other papers indicate that non-velocity redshifts have been observed.
If a non-Doppler redshift mechanism cannot exist, all of these papers published by professional astronomers would have to be erroneous! This arouses suspicion, to say the least. The systematic rejection of more than 1,000 papers related to nonvelocity redshift observations show that many scientists are too comfortable with the established framework to be open to ideas that challenge that framework. A non-Doppler interpretation of the redshift actually leads to better agreement of theory with the actual observations, as shown below.Light Element Production.
It is not necessary to invoke a Big Bang in order to explain the observed abundances of light elements. A plasma model of galaxy formation accomplishes the task very well (Rees 1978; Lerner 1989). The plasma model shows that the elements are produced during galaxy formation in their observed abundances by early massive and intermediate stars. The nuclear reactions and cosmic rays generated in and by these stars lead to production of the elements. As a recent reviewer of plasma theory wrote, the plasma model: "accounts accurately for the observed overabundance of oxygen in the lowest metallicity stars, and deuterium, and does not over-produce the remaining rare light elements - lithium, beryllium, and boron" (Lerner 1989).Cosmic Background Radiation.
The existence of the 3 K microwave radiation is no longer valid evidence for the Big Bang. There is no need to assume, as Big Bang believers do, that this background radiation came from a highly Doppler-redshifted blackbody (3) at about 3,000. K - that is, from the exploding ball of matter - when its density became low enough for energy and matter to decouple. The background radiation is simply Planck's blackbody radiation emitted by our unlimited universe that is also at a temperature of about 3 K (Marmet 1988).
The inhomogeneity of matter in the universe today means that there should be some inhomogeneity in the cosmic background radiation if it originated in a Big Bang. But no fundamental inhomogeneity in the background has been clearly found, despite tests that are sensitive down to small scales. Matter is concentrated in galaxies, in clusters and super clusters of galaxies, and in what has been called the Great Attractor (a tentatively identified but huge concentration of mass centered 150 million light-years away). These important inhomogeneities in the composition of the universe as we see it today must have first appeared in the early universe (if it exists). In fact, a comparable inhomogeneity must have existed in the matter that emitted the 3 K radiation. That inhomogeneity must appear as a distortion in the Hubble flow (4) (Dressler 1989) and must lead to observable irregularities in the 3 K background. Inhomogeneities in the 3 K radiation have been looked for, but nothing is compatible with the mass observed in the Great Attractor. A. E. Lange recently reported that there is no observable inhomogeneity even with a resolution of 10 seconds of arc and a sensitivity in temperature as high as D T= ± 0.00001 K (Lange 1989).
Nor can Einstein's general theory of relativity be applied in a consistent manner to the Big Bang model. According to the model, when the universe was the size of an electron and was 10 -23 second old, it was clearly a black hole - a concentration of mass so great that its self-gravitation would prevent the escape of any mass or radiation. Consequently, according to Einsteinian relativity, it could not have expanded. Therefore, one would have to assume that gravity started to exist only gradually after the creation of the universe, but that amounts to changing the laws of physics arbitrarily to save the Big Bang model. In contrast, an unlimited universe as suggested here agrees with Einstein's relativity theory, taking into account the cosmological constant (5) that he proposed in 1917.
Recent astronomical discoveries pose an additional and very serious problem for the Big Bang theory. Larger and larger structures are being found to exist at greater and greater redshifts, indicating their existence in the increasingly distant past. (Whether one assumes the Big Bang or the theory presented here, the redshift is normally an indicator of distances, and because it takes time for light to travel, the image of a highly redshifted object is seen on Earth today as it was when the light began to travel.)
In 1988, Simon Lilly of the university of Hawaii reported the discovery of a mature galaxy at the enormous redshift of 3.4; that is, the amount of the redshift for any spectral line from the galaxy is 340 per cent of the line's proper wavelength (Lilly 1988). This puts the galaxy so far in time that the Big Bang scheme does not allow sufficient time for its formation! In a news report on Lilly's work, Sky & Telescope reports: "The appearance of a mature galaxy so soon after the Big Bang poses a serious threat . . ." (Aug. 1988, p. 124).
In 1989 came the discovery of the "Great Wall" of galaxies, a sheet of Galaxies 500 million light-years long, 200 million light-years wide, and approximately 15 million light-years thick, with the dimensions of the structure being limited only by the scale of the survey (Geller and Huchra 1989). It is located between 200 and 300 million light-years from Earth. In an interview with the Boston Globe (Nov. 17 1989), Margaret Geller of the Harvard-Smithsonian Center for Astrophysics offered some frank comments on the implications of her discovery:The size of the structure indicates that in present theories of the formation of the universe "something is really wrong that makes a big difference,"Geller said in an interview yesterday:
No known force could produce a structure this big in the time since the universe was formed", She said.4 --- The Redshift and the Intergalactic Medium.
All the observed phenomena cited above can be explained without recourse to the Big Bang theory. But what about the cosmic redshift, the central subject of this article? This author has explained the cosmic redshift by improving our understanding of the interaction of light with atoms and molecules. The observational fact upon which Big Bang advocates and opponents agree is that the redshift of galaxies generally increases with distance. This relationship would arise if the light we receive from galaxies loses some of its energy to the intergalactic medium through which it must pass. In that case, the greater the depth of the intergalactic medium between a galaxy and the observer, the more its light is shifted toward the low-energy (red) end of the spectrum.
A redshift from the interaction of photons with atoms in the galactic and intergalactic media was previously denied: Most scientists are accustomed to thinking that when photons interact with the medium through which they pass, losing some energy in the process, some significant angular dispersion of the photons must result. Most of the light from other galaxies, they say, cannot undergo any appreciable interaction with the intervening medium, because the resulting angular dispersion would cause their images to become blurred, and our images of other galaxies are, indeed, not blurred.
The usual explanation of how light travels through gases, however, is inconsistent and incomplete. Physicists understand that when a beam of light passes through the atmosphere, a fraction of the photons interacts with the medium and loses energy to it, undergoing angular dispersion. This is known as Rayleigh scattering after British physicist John Rayleigh. Most physicists assume that the rest of the light, which suffers no dispersion, passes through the medium without interaction. Given the density of the atoms and molecules of the atmosphere, however, this is clearly impossible.
A more sensible conclusion is that most interactions involve an atom or molecule absorbing a photon and reemitting it in the forward direction. We shall see that these interactions are inelastic; that is, the reemitted photons have lost some of the original energy to the atom or molecule, and hence their wavelengths are longer (redder) (Marmet 1988); (Marmet and Reber (1989). The familiar concept of the index of refraction exposes the problem to view. The velocity of light (group velocity) is reduced in gases, relative to its velocity in a vacuum, as expressed by the index of refraction. The derivation of the index of refraction assumes that matter is homogenous and that one neglects the existence of individual atoms. The reduced velocity applies to all of the light. At atmospheric pressure, one does not easily notice this reduced speed of propagation in air, precisely because almost all photons are transmitted without angular dispersion (scattering).
At a distance of 100 meters, for example, it is everyday experience that light is transmitted through calm air without any noticeable angular dispersion and does not produce any visible fuzziness - even when images are observed through a telescope. The index of refraction of air (n=1.0003) shows that interactions or collisions of photons on air molecules are such that the photons are delayed by 3 centimeter in a trajectory of 100 meters, with respect to transmission in a vacuum (see Figure 1). Only that small delay of 3 cm can be explained by a large number of photon-molecule collisions.MOST PHOTONS DO NOT UNDERGO ANGULAR DISPERSION WHEN THEY INTERACT WITH MOLECULES.
Figure 1Light transmitted through air is slowed by its interaction with air molecules. In the same time, that light traverses 100 meters in a vacuum (a), it traverses only 99.97 meters in air (b). This is expressed in the index of refraction for air, 1.0003. Many photon-molecule interactions are required to explain such a long delay. Since an object seen at 100 meters is not fuzzy, one must conclude that these photon-molecule interactions do not lead to angular dispersion of most of the light, although this is still the common assumption. In fact, the photons must be reemitted from such interactions in the forward direction.
A delay of 3 cm corresponds to about one billion the size of the atom. Therefore we can be sure that not only all photons had more than one interaction with air molecules, but that it must take on the order of one billion collisions to produce such a delay. The photons have undergone about one billion collisions with air molecules without any significant angular dispersion, because the image is not fuzzy. Photon-molecule collision without angular dispersion is an everyday experience that has been completely overlooked.
In space, where the gas density is lower by more than 20 orders of magnitude, the same phenomenon takes place. A photon undergoes about one interaction (due to the index of refraction, with no angular dispersion) per week.; Rayleigh scattering producing diffusion in all directions, is enormously less frequent just as in the atmosphere. Hence, almost all interactions of photons with gas molecules take place without any measurable angular dispersion.5 --- The Consequences of these Interactions.
What then are the consequences of these interactions? It is necessary to examine the character of photon collisions with individual atoms. We have just seen above that the collisions produce a delay in the transmission of light; Therefore, there is a finite interval of time during which the photons is absorbed before being reemitted.
An atom is polarized, in a transverse direction, by the passage of electromagnetic waves (photons) moving across it. The positively charged nucleus is attracted on one direction while the negatively charge surrounding electrons cloud is attracted in the other. In this field, at least a part of the energy of the electromagnetic wave is transmitted, in the axial direction, to the electron of the atom. This is called a polarized atom (with an energy of polarization). The momentum (6) of this transferred energy necessarily gives an acceleration to the electron, causing a secondary photon to be emitted, a phenomenon known as bremsstrahlung (braking radiation) (see Figure 2).It is a very rare physicist who recognizes that photons must always lose energy in interacting with atoms and molecules. The author demonstrates the truth of this assertion however in 1980, using semi classical electrodynamics to explain and calculate the energy loss. In the diagram, a photon is being absorbed and reemitted in the forward direction by an atom, which emits at least one very soft (long-wavelength) secondary photon in the process.
Figure 2
PHOTONS ALWAYS LOSE ENERGY INTERACTING WITH ATOMS.It has been calculated that under ordinary conditions, the energy loss per collision is about 10 -13 of the energy of the incoming photon (Marmet 1988). Hence the phenomenon produces a redshift that follows the same rule as the Doppler effect: Whatever the wavelength emitted by the source, the relative change of wavelength is constant ( Dl / l =constant). The secondary photon (bremsstrahlung photon), which carries away the lost energy, has a wavelength several thousand kilometers long. Because the longest wavelength observed so far in radio astronomy is 144 meters (Reber 1968, 1977), these secondary photons of very long wavelength cannot yet be detected. They are, however, predicted by electrodynamics theory.
CAPTION OF FIGURE 3
Marmet's photon-atom interaction theory mentioned above is the only "non ad-hoc" explanation predicting the amount and the rate of change of the solar redshift (solid line labeled Marmet). The experimentally determined redshift on the solar disk, moving from the disk's center (Sin q =0) to its limb (Sin q =1.0), is shown in the dotted and dashed curves. Observational values of Adam (1948) and Finlay-Freundlich (1954). The redshift is given in wavelength units of 10 -13 meters on the y-axis. Other theories that attempt to explain this redshift as a Doppler effect produces the two upper curves: Schatzman and Magnan (1975), motion of gas in the solar granules) and Finlay-Freundlich (1954), motion in the photosphere and chromosphere). Allowances has been made for the differential Doppler shift arising from the Sun's rotation.The conclusion that interactions of photons with atoms must always result in the production of secondary photons has been derived from quantum electrodynamics (Jauch and Rohlich 1980); Bethe and Salpeter (1957), and was independently derived by this author from classical electrodynamics (Marmet 1988). However, only the last-mentioned study was able to predict the amount of energy lost in the process.
6 --- Experimental Confirmation.
Experimental confirmation of the theory of the redshift developed here has been achieved in several instances, with observations of the Sun (Marmet 1989), binary stars, and other cases (Marmet 1988a; Marmet and Reber 1989). Perhaps the most dramatic of these confirmations is in the case of the Sun, where the theory has been applied to the redshift anomaly associated with the solar chromosphere. When spectroscopic measurements are made of light from the center of the Sun's disk and compared with those from the limb (edge of the disk), the latter are found to be redshifted with respect to the former - Above and beyond the Doppler shift that arise from the Sun's rotation. This anomaly was first reported in 1907, and has been confirmed by all experts in the field.
Attempts have been made to explain this redshift as a Doppler effect on the basis of the motion of masses of gas in the photosphere and chromosphere, or such motions in the solar granules (convection cells). The inadequate predictive power of these hypotheses can be seen in Figure 3. The figure shows the observed amount of the redshift as a function of the position between the center of the redshift as a function of position between the center of the Sun's disk and the limb, and compares this observed curve to the curves required by two of these theories.
If, however, the redshift arises from the increasing number of photon-atom interactions between source and observer as the spectroscope sample positions nearer the limb (Figure 4), the theory developed here applies, and provides an accurate prediction of the observed curve) Figure 3). The theory is also successful in explaining the absence of redshifting for several spectral lines in terms of their known origin in very high layers of the Sun, and in explaining a stronger redshift for the iron line at 5,250 angstroms in terms of its known origin in a deeper layer.7 --- Is there Enough Matter in Space?
Is there enough matter in space to account for the observed redshift in terms of the theory offered here? An average concentration of about 0.01 atom/cm 3 is required to produce the observed redshift, as given by the Hubble constant (Marmet 1988b). This required density of matter in space is larger than what has been measured experimentally until presently, but our ability to detect such matter is still very imperfect. Almost all of our methods of detection are selective and can detect only one kind of matter. Most methods use spectroscopy to detect radiation emitted or absorbed by the matter. There are strong reasons for thinking that there is much more matter in space than has been observed.
Although atomic hydrogen is found extensively in space and can be detected by the emission and absorption of its characteristic radiowaves of 12-cm wavelength, it is likely that cold atomic hydrogen condenses to the molecular form (H 2 ), which must be also present extensively in space. Cold molecular hydrogen and helium, however, are undetectable at visible or radio wavelengths. Since molecular hydrogen (H 2 ) has no permanent electric dipole (7) , it does not easily emit or absorb radiation. Most excited molecules emit photons in about 10 -8 second. However, the spontaneous emission of the first rotational state of molecular hydrogen is practically nonexistent (rotational states are different molecular energy levels) even after many thousands of years. A transition (by spontaneous emission) from the second rotational state of molecular hydrogen is relatively much more probable but would require about 30 billion seconds (about 1,000 years). That is about 18 orders of magnitude less probable than an ordinary dipole transition. At the sixth rotational state the quantum transition still takes as much as one year.
The extreme rarity of these "forbidden" transitions means that one cannot hope to detect molecular hydrogen spectroscopically. Only in the far ultraviolet portion of the spectrum can some molecular hydrogen be detected in the neighborhood of ultraviolet-emitting stars. Because of its nature, molecular hydrogen is very likely extremely abundant in space - but not detectable with methods now available.
Caption of Figure 4
Application of the Photon-Atom Interaction Theory to the Solar Redshift.
Light observed at the center of the solar disk along line of sight A, passes through an amount of solar atmosphere represented by "a". Light observed at the solar limb along line of sight B passes through a much larger amount of solar atmosphere represented by "b". (A and B converge at the observer). Hence the photon-atom interaction theory predicts an increasing redshift toward the limb.There are other indications of large amounts of invisible matter in the universe. For example, it has been unexpectedly discovered that the matter in galaxies may extend to as much as 10 times the radius of its visible component. This possibility arises from the study of differential rotational velocity of the matter in galaxies. From the laws of orbital motion, we expect the orbital velocity of matter (in kilometers per second, for example) to fall off as the square of the total mass enclosed within the orbit. In other words, in moving from a galaxy's nucleus to its periphery, we expect to encounter ever lower velocities, just as in the solar system the outer planets move more slowly. Instead, it has been found that the velocity remains roughly constant. The conclusion drawn from this apparent deviation from the laws of motion is that there must be an important amount of invisible matter in galaxies, comprising as much as 90 to 99 percent of the whole (Rubin 1983, 1988). It is reasonable to expect that a still much larger amount of invisible matter lies farther out, around galaxies.
The Big Bang model suffers from crucial failures that are becoming increasingly serious with continuing progress in astronomical observations. These observations, however, are consistent with a universe that is unlimited in time and space. The density of matter that may exist in intergalactic space - allowing for molecular hydrogen - is compatible with the density (about 0.01 atom/cm 3 ) required in the author's cosmological model. At the same time, the background radiation predicted in an unlimited universe is compatible with the high homogeneity of the observed 3 K background (Marmet 1988).It is clear that God did not limit Himself to a finite universe at one time and place, but made the universe in His own image, infinite in space and time.======================== ========================About the Author.
Dr. Paul Marmet was a senior researcher at the Herzberg Institute of Astrophysics of the National Research Council of Canada, in Ottawa from 1983-1990. From 1967 to 1982, he was director of the laboratory for Atomic and Molecular Physics at Laval University in Québec city. Later, from 1990 to 1999, his teaching and research was at the physics department of the University of Ottawa.
A past president of the Canadian Association of Physicists, he also served as a member of the executive committee of the Atomic Energy Control Board of Canada from 1979 to 1984. Marmet has been elected Fellow of the Royal Society of Canada in 1973 and was made an Officer of the Order of Canada in 1981 - The Order of Canada is the highest decoration bestowed by the Canadian government.
The Author's Electron Beam Device.
Paul Marmet (Who's Who) is shown here at the Herzberg Institute of Astrophysics in Ottawa with the electron spectrometer he pioneered. The spectrometer developed during his Ph. D. thesis (1960), produces a very low-energy monoenergetic electron beam (0 to 100 eV) in vacuum, which is used to study the internal structure of atoms and molecules. That new spectroscopy uses a beam of monoenergetic electrons instead of photons used by most spectroscopists. As in other electron beams devices, the free electrons are produced by heating a filament in high vacuum. Just after emission, electrons in such a beam vary in their individual energies by 1 eV or more. In Marmet's spectrometer, the spread of electron energies is reduced to 10 millivolts, so that the results of the interaction provide information on a scale that is finer by a factor of 100. Also, an electrodynamic quadrupole mass spectrometer with hyperbolic electrodes is used since the sensitive electron source required a complete magnetic field free environment. The ion current is measured counting individual ions.
In the ion source, the electron beam is fired into a collimated beam of atoms or molecules directed at right angle to it. The number of ions produced in the resulting interactions, as a function of the electron energy, provides the information about the electron configuration in the atoms and molecules. The energy of the electron beam gives the absolute energy of the quantum state.
The advantages of using an electron beam instead of photons are multiples. Since photons do not carry electric charges, they cannot produce directly negative ions. The absence of an electric charge in photons is responsible for the fact that most of the negative ions are ignored in physics. The energy of excited negative ion states is a very undeveloped field in physics. These negative ions are so important in the experiments in plasma physics.
Using this electron beam, this instrument measured multiple electronic states of negative ions of Hydrogen, Helium, Nitrogen, Oxygen, all the halogens and also numerous diatomic molecules like carbon monoxide, methane, and many others. Even doubly or triply excited states of negative ions can be measured and identified. For example, using that electron beam, this instrument could discover and measure negative Helium ions with all three electrons in an excited state [i.e. He(2s 2 2p)]. Of course, these short-lived quantum states cannot be measured using photon spectroscopy. It was also interesting to measure different quantum states (and their half-life) of diatomic Argon(minus) molecules, (and all other inert gases), which remain stable long enough to be measured in the mass-spectrometer. Using that monoenergetic electron beam, several hundred states have been discovered in numerous atoms and molecules. Finally, using the filtering power of the mass spectrometer, several free radicals have been studied.
Marmet and his mentor, Larkin Kerwin, describe their pioneer work on this electron source in Citation Classics, Nov. 23 1987. More than 100 scientific papers (papers) of spectroscopic data and interpretations have been published on this subject. Furthermore, about 200 other papers have been presented in numerous international and national meetings.
Between 1978 and 1998, the author also published several other papers related to the fundamental principles in physics. Several of these papers are presented on this web site at (list). In 1997-99, physicists of the establishment showed their fierce disagreement with the fact that Marmet’s research implied that the fundamental principles were being questioned. Although the experimental work, which could determine the energy of numerous quantum stated was highly appreciated (and even honored), the physics establishment required that the author should stop questioning the fundamental principles of physics. For example, the author was first informed by the NSERC committee (Natural Science and Engineering Research Council of Canada) to stop doing that fundamental research, despite the fact that, being theoretical, it required no research funds. All research grants were used for the experimental work needed for the electron impact apparatus. Since the fundamental research was still going on the following year, the NSERC committee decided to cut to zero the grant given for the experimental work using the monoenergetic electron beams.
In May 1999, the head of the physics department (Dr. Bela Joos) of the university of Ottawa, came to Marmet’s office and said: “Ce n’est pas ton bureau que nous voulons, ton problème est que tu remets en question les principes fondamentaux de la physique.” (This statement was immediately noted by writing). This can be translated by: “We do not want your office, your problem is that you keep questioning the fundamental principles of physics.” Three months later, (August, 24 th 1999), I received a letter from Dr. Bela Joos, requiring my office to become unoccupied before the end of the month. Without research grant and being expelled from my office I had to continue my fundamental research alone at home.
This was the irrevocable death of a unique instrument in the world, which was able to measure the negative ions in the ionization efficiency curve, using a monoenergetic electron beam. A few months later, the instrument was destroyed.
This is the story of a unique instrument capable of measuring the electronic structure of negative ions. Also, this shows that physics is not a science: It is a doctrine. Therefore, there are heretics.
How different is it from Galileo’s time? No difference.

The wavelength of radiation observed is longer (redshifted) than the wavelength emitted when it comes from a source that is moving away from the observer, a discovery made by J. C. Doppler in 1842. Likewise, the wavelength observed becomes shorter (blueshifted) when the object is approaching the observer. The redshift of light from remote galaxies is usually interpreted as being caused by the relative motion of these galaxies away from our own, in an expanding universe.

"3 K" means a temperature of 3 degrees on the absolute scale (Kelvin), 3 K is equal to -270 degrees Celsius. All bodies emit electromagnetic radiation in accord with their temperature. For example, a hot filament emits visible light. At 3 K, the electromagnetic radiation emitted is in the microwave range with a wavelength of about 1 mm. The "3 K background radiation" is the radiation observed from all directions in the universe that has the same wavelength distribution as that emitted by a blackbody at a temperature of 3 K.

When a hot blackbody emits electromagnetic radiation, it emits the range of frequencies at varying rates described by a curve known as the Planck function. Using this function, one can predict the distribution of wavelengths and rates emitted by any blackbody if one knows its temperature. If the surface is not black (such as gray, semitransparent or a mirror) the rates emitted are different.

In the Big Bang theory, matter flows away from the observer at a velocity that depends on its distance from him.

I am now going to supply what looks to me like a good summary comparative analysis between the Big Bang model and Other Non-Conventional Models of the Universe:
Information of Big BangIn astrophysics, the term Big Bang is used both in a narrow sense to refer to the interval of time roughly 13.7 billion years ago when the photons observed in the microwave cosmic background radiation acquired their black-body form, and in a more general sense to refer to a hypothesized point in time when the observed expansion of the universe (Hubble's law) began. According to the Big Bang theory, the universe originated in an infinitely dense singularity. Space has expanded with the passage of time, objects being moved farther away from each other.
In
cosmology, the Big Bang theory is the prevailing scientific theory about the early development and shape of the universe. The central idea is that the observation that galaxies appear to be receding from each other can be combined with the theory of general relativity to extrapolate the conditions of the universe back in time. This leads to the conclusion that as one goes back in time, the universe becomes increasingly hot and dense.
There are a number of consequences to this view. One consequence is that the universe now is very different than the universe in the past or in the future. The Big Bang theory predicts that at some point, the matter in the universe was hot and dense enough to prevent light from flowing freely in space. That this period of the universe would be observable in the form of cosmic background radiation (CBR) was first predicted in the 1940s, and the discovery of such radiation in the
1960s swung most scientific opinion against the Big Bang theory's chief rival, the steady state theory.Using current physical theories to extrapolate the Hubble expansion of the universe backwards leads to a
gravitational singularity, at which all distances become zero and temperatures and pressures become infinite. What this means is unclear, and most physicists believe that this is because of our limited understanding of the laws of physics with regard to this type of situation, and in particular, the lack of a theory of quantum gravity.There are actually many theories about the Big Bang. Some theories purport to explain the cause of the Big Bang itself, and as such have been criticized as being modern
creation myths. Some people believe that the Big Bang theory lends support to traditional views of creation, for example as given in Genesis, while others believe that all Big Bang theories are inconsistent with such views. The relationship between religion and the Big Bang theory is discussed below.Based on measurements of the expansion of the universe using
type I supernovae, measurements of the lumpiness of the cosmic microwave background, and measurements of the correlation function of galaxies, it is currently believed that the universe has an age of 13.7 ? 0.2 billion years. The fact that these three separate measurements of completely different things are all consistent with each other is considered strong evidence for the model.The universe as we know it was initially almost uniformly filled with energy and extremely hot. As the distances in the universe rapidly grew, the temperature dropped, leading to the creation of the known
forces of physics, elementary particles, and eventually hydrogen and helium atoms in a process called Big bang nucleosynthesis.Over time, the slightly denser regions of the almost, but not quite, uniformly distributed matter were pulled together by
gravity into clumps, forming gas clouds, stars, galaxies, and the other astronomical structures seen today. The details of how the process of galaxy formation occurred depends on the type of matter in the universe, and the three competing pictures of how this occurred are based on the properties of three types of matter known as cold dark matter, hot dark matter, and baryonic matter. These three models have been tested through computer simulations and observations of galactic correlation functions. The best measurements available (from WMAP) show that the dominant form of matter in the universe is in the form of cold dark matter. The other two types of matter make up less than 20% of the matter in the universe.It is at present unknown whether the
singularity of spacetime described above is a physical reality or just a mathematical extrapolation of general relativity beyond its limits of applicability. The resolution of this depends on a theory of quantum gravity, which is not currently available. Nevertheless, there has been intense theoretical work on trying to figure out what happened before the Big Bang. Some of these efforts involve the ekpyrotic universe, and there has also been interest in the anthropic principle.In general relativity, one usually talks about spacetime and cannot cleanly separate space from time. In the Big Bang theory, this difficulty does not arise;
Weyl's postulate is assumed and time can be unambiguously measured at any point as the "time since the Big Bang". Measurements in this system rely on so-called conformal distances and times which removes the expansion of the universe from consideration of spacetime measurements.The Big Bang was not an explosion of matter moving outward to fill an empty universe; it is space itself that is expanding. So, bizarre as it may seem, the distance between any two fixed points in our universe is increasing. Intuitively this seems impossible: if the distance between two things increases then it seems that by definition one or both must be moving. But this is not so, as becomes clear if you consider the simplistic but logically equivalent model of a universe of constant size (whether finite or infinite), in which everything is shrinking. The people who live in this universe are shrinking too, as are all their scientific instruments. When these people measure the distance between two points that are sufficiently far apart, the distance will seem to be increasing, because the yardsticks they use to measure with are shrinking along with everything else. The fundamental assumption in this idea is that spacetime on the largest scales is unaffected by locality; objects that are bound together do not expand with spacetime's expansion because local forces keep them together. The expansion of the universe on local scales is so small that the difference of any local forces is unmeasurable by current techniques.
Because it is space itself that is expanding, and not a case of objects flying apart through space, the distance (in the sense of
comoving distance) between far removed galaxies can increase faster than the speed of light without violating the laws of special relativity. Literatur:Bye Bye Big Bang: Hello Reality [Authors: William C. Mitchell]In
1927, the Belgian priest Georges Lema?e was the first to propose that the universe began with the explosion of a "primeval atom". Earlier, in 1918, the Strasbourg astronomer Wirtz had measured a systematic redshift of certain "nebulae", and called this the K-correction, but he wasn't aware of the cosmological implications, nor that the supposed nebulae were actually galaxies outside our own Milky Way.Einstein's theory of
general relativity developed during this time had the result that the universe could not remain static, a result that he himself considered wrong, and which he attempted to fix by adding a cosmological constant which did not fix the problem. Applying general relativity to cosmology was done by Alexander Friedmann whose equations describe the Friedmann-Robertson-Walker universe.In the 1930s,
Edwin Hubble found experimental evidence to help justify Lema?e's theory. Hubble had also determined that galaxies were receding back in 1913. Again using redshift measurements, Hubble determined that distant galaxies are receding in every direction at speeds (relative to the Earth) directly proportional to their distance, a fact now known as Hubble's law.Since galaxies were receding, this suggested two possibilities. One, advocated and developed by
George Gamow, was that the universe began a finite time in the past and has been expanding ever since. The other was Fred Hoyle's steady state model in which new matter would be created as the galaxies moved away from each other and that the universe at one point in time would look roughly like any other point in time. For a number of years the support for these two opposing theories was evenly divided.In the intervening period however, all observational evidence gathered has provided overwhelming support for the Big Bang theory, and since the mid-
1960s it has been regarded as the best available theory of the origin and evolution of the cosmos, and virtually all theoretical work in cosmology involves extensions and refinements to the basic Big Bang theory. Much of the current work in cosmology includes understanding how galaxies form within the context of the Big Bang, understanding what happened at the Big Bang, and reconciling observations with the basic theory.Huge advances in Big Bang cosmology were made in the late 1990s and the early 21st century as a result of major advances in
telescope technology in combination with large amounts of satellite data such as from COBE and WMAP. This data allowed astronomers to calculate many of the parameters of the Big Bang to new precision and opened up a major unexpected finding that the expansion of the universe appears to be accelerating.Over the decades a number of weaknesses have been identified in the Big Bang theory, but these have thus far all been addressed by extensions and refinements such as
cosmic inflation. As of 2003, there are no weaknesses in the Big Bang theory which are regarded as fatal by most or even a large minority of cosmologists. However, some cosmologists still support non-standard cosmologies in which the Big Bang does not occur.Recent research has been refining the Big Bang by including a model for the matter within the universe to understand the process of galaxy formation. Most current models are based on the notion of
cold dark matter which has supplanted other models of hot dark matter and baryonic matter. As of 2003, theories based on cold dark matter still have some conflicts with observations, namely the Dwarf galaxy problem and the cuspy halo problem.See also:
Timeline of the Big BangIn describing the evidence for the Big Bang, it is necessary to distinguish between observations which are also consistent with other theories, and observations which are not easily explained by other theories. The former category includes the observations that the universe appears to be isotropic, that galaxies appear to be receding from each other, and that the sky is dark (see Olbers's paradox). While these observations are all consistent with the Big Bang theory, each of them is also consistent with at least one other theory, such as Fred Hoyle's steady-state universe and Hannes Alfven's plasma universe.
The observations which are readily explained within the Big Bang framework but which are not so easily explained otherwise are as follows.
One feature of the Big Bang hypothesis was the prediction in the 1940s of the discovery of the cosmic microwave background radiation or CMBR. According to the Big Bang theory, as all the mass/energy of the universe emerged from a primordial explosion, the initial density of the universe must have been incredibly high. Since matter cools when it becomes less dense, the early universe must have been extremely hot. In fact, the temperature of the very early universe must have been so high that matter as we know it could not exist, because the subatomic particles would have been too energetic to aggregate into atoms.
However, as the temperature of the universe fell, the theory predicted that more familiar forms of matter would form from the
primordial plasma. At some stage (currently reckoned to be around 500,000 years after the beginning), the temperature would fall below 3000 K. Above this temperature, electrons and protons are separate, making the universe opaque to light. Below 3000 K, atoms form, allowing light to pass freely through the gas of the universe. This is known as photon decoupling.The Big Bang theory therefore predicts that if you look far enough into space, and hence far enough back in time, you will eventually see the location at which the universe becomes opaque to radiation. The radiation from this region will be redshifted because of the Hubble expansion. This results in the visible spectrum of the 3000 kelvin radiation from the opaque region to be redshifted to a much lower temperature. The radiation should be almost completely isotropic.
At the time they were made and for the next 20 years, the predictions of the Big Bang theory regarding CMBR were largely ignored, simply because they remained unverifiable due to inadequate technology. Initially, George Gamow calculated that the CMBR should appear as a black body radiating at 50K. He later revised the calculation and estimated the temperature of the CMBR as about 5K. This was an error being somewhat higher than the 2.73K black body later observed.
In
1964, Arno Penzias and Robert Wilson conducted a series of diagnostic observations using a new microwave receiver owned by Bell Laboratories (which was designed for normal telephone communications) and accidentally discovered the cosmic background radiation originally predicted by Gamow. This observation was later confirmed by the Peebles group at Princeton University, who were themselves trying to construct a microwave antenna with a ruby maser to detect the CMBR when Penzias and Wilson made their serendipitous discovery. It was not until Penzias and Wilson consulted with the Peebles group that they understood what it was they had detected. Penzias and Wilson published their findings jointly with the Peebles group in the Astrophysical Journal.Their discovery provided substantial confirmation of the general CMBR predictions (though it required correction of inaccurate values), and pitched the balance of opinion in favour of the Big Bang hypothesis. Penzias and Wilson were awarded the Nobel Prize for their discovery.
In
1989, NASA launched the Cosmic Background Explorer satellite (COBE), and the initial findings, released in 1990, were consistent with the Big Bang theory's predictions regarding CMBR, finding a local residual temperature of 2.726 K, determining that the CMBR was generally isotropic, and confirming the "haze" effect as distance increased. During the 1990s, CMBR data was studied further to see if small anisotropies predicted by the Big Bang theory would be observed. They were found in the late 1990s.In early 2003 the results of the
Wilkinson Microwave Anisotropy satellite (WMAP) were analysed, giving the most accurate cosmological values we have to date. This satellite also disproved several specific inflationary models, but the results were consistent with the inflation theory in general.Using the Big Bang model it is possible to calculate the concentration of
helium-4, helium-3, deuterium and lithium-7 in the universe. All the abundances depend on a single parameter, the ratio of photons to baryons. The abundances predicted are about 25 percent for 4 He, a 2 H/H ratio of about 10 -3 , a 3 He/H of about 10 -4 and a 7 Li/H abundance of about 10 -9 .Measurements of primordial abundances for all four
isotopes are consistent with a unique value of that parameter (see Big Bang nucleosynthesis), and the fact that the measured abundances are in the same range as the predicted ones is considered strong evidence for the Big Bang. There is no obvious reason outside of the Big Bang that, for example, the universe should have more helium than deuterium or more deuterium than 3 He. Thus far, no other theory has attempted to make the nucleosynthetic predictions that the Big Bang does.Theories which assert that the universe has an infinite life such as the
steady state theory fail to account for the abundance of deuterium in the cosmos, because deuterium easily undergoes nuclear fusion in stars and there are no known astrophysical processes other than the Big Bang itself that can produce it in large quantities. Hence the fact that deuterium is not an extremely rare component of the universe suggests that the universe has a finite age.Theories which assert that the universe has a finite life but that the Big Bang did not happen have problems with the abundance of
helium-4. The observed amount of 4 He is far larger than what could be created via stars or any other known process. By contrast, the abundance of 4 He are very insensitive to assumptions about baryon density changing only a few percent, as the baryon density changes by several orders of magnitude. The observed value of 4 He appears to be within the range calculated.This having been said, there are three theoretical issues with Big Bang nucleosynthesis which have some potential of undermining the theory. The first is that the baryon concentration necessary to get an exact match with the current abundances is inconsistent with a universe with mostly baryons. The second is that the Big Bang predicts that no elements heavier than lithium would have been created in the Big Bang, yet elements heavier than lithium are observed in quasars, which presumably are some of the oldest galaxies in the universe. The third problem is since big bang nucleosynthesis produces no elements heavier than lithium, then we ought to see some long lived remnant stars which have no heavy elements in them. We don't.
The standard explanation for the first are that most of the universe isn't composed of baryons. This explanation fits nicely with other evidence of
dark matter such as galaxy rotation curves. The standard explanation for the second and third is that the universe underwent a period of massive star formation creating large high mass stars and that without heavy elements, forming low mass red dwarf stars is impossible. This explanation has the feature that it predicts a class of stars that, as of 2004, have not been observed. Hence, in a few years we should have either seen them, which would support the big bang scenario, or we won't, in which case there is a possibility that we will have to fundamentally alter our views of the universe.One observation that has become increasingly apparent since the early 1970s is that while the universe appears to be isotropic in space (i.e. the universe in one direction looks very much like the universe in another direction) it is not uniform with respect to distance (due to the finite speed of light, greater distances represent earlier times in the past). As one looks to increasingly large distances, the universe looks very different. For example, there are no nearby
quasars, but there are many quasars once you pass a given redshift, and then the quasars disappear at a still further distance. Similarly, the types and distribution of galaxies appears to change markedly over time and once one passes a given distance, the number of galaxies fall off considerably.Throughout its history, a number of criticisms have been offered against the Big Bang theory. Some of them are today mainly of historical interest, and have been removed either through modifications to the theory or as the result of better observations. Others issues, such as the
cuspy halo problem and the dwarf galaxy problem of cold dark matter, are considered to be non-fatal as they can be addressed through relatively minor adjustments to the theory. Finally, there are proponents of non-standard cosmologies who believe that there was no Big Bang at all.One unanswered question is how the Big Bang might have occurred. The difficulty of answering this question lies with the absence of a theory of quantum gravity. As one goes back in time, the temperature and the pressures increase to the point where the physical laws governing the behavior of matter are unknown. It is hoped that as we understand these laws that we will better be able to answer the question of what happened "before" the Big Bang.
The magnetic monopole problem was an objection that was raised in the late-1970s.
Grand unification theories predicted point defects in space which would manifest themselves as magnetic monopoles, and the density of these monopoles was much higher than what could be accounted for. This problem is resolvable by the addition of cosmic inflation.The horizon problem results from the premise that information cannot travel faster than light, and hence two regions of space which are expanding at faster than the speed of light relative to each other cannot communicate. This means that there is no mechanism to ensure that they have the same temperature. In the
1970s, no anisotropies had been observed which contradicted non-inflationary theories of the Big Bang. This problem was partially resolved by cosmic inflation which reduced the horizon problem by arguing that the early universe suddenly underwent a period of massive expansion before which regions that would later not be in contact with each other could equalize their temperatures.However, cosmic inflation predicted that the anisotropies in the Big Bang would be reduced but not eliminated. Even with inflation, there would be regions of space that could not be in thermal contact. In the early
1990s, there was some excitement and nervousness, as satellite detectors such as COBE at first failed to detect any anisotropy, and various inflationary scenarios began to be invalidated. Had another few years passed without any detections of anisotropy, the Big Bang would have been very badly hurt, but this was not the case, and the expected anisotropies were detected.The horizon problem is still of major interest because it allows one to deduce large amounts of information from the CMB. Different expansion rates will result in different amounts of lumpiness in the CMB as a result of material falling past the horizons at different times, and this provides much data about the conditions within the universe at the time the CMB was formed.
One major issue that had the potential of challenging the Big Bang occurred in the mid-1990s. Computer simulations of globular clusters suggested that they were about 15 billion years old, which conflicted with some values of the Hubble constant suggesting that the universe was 10 billion years old. This issue was resolved in the late 1990s with other new computer simulations which included the effects of mass loss due to stellar winds indicated a much younger age for globular clusters.
During the mid-1990s, measurements of the amount of primordial helium abundance suggested the possibility that the helium abundance of the first stars would have been less than 20%. If this were the case, it would have posed major problems for the Big Bang theory, as it is very difficult to get low amounts of helium from the Big Bang. This potential problem was resolved in the late-1990s by better measurements of helium abundances.
As mentioned earlier, there are also issues with the baryon density and the observation of heavy elements with quasars. These are widely considered to be less serious challenges to the Big Bang, however, they have the potential to undermine the theory if explanations advanced for them prove inadequate.
For example, the consensus is that in order to explain heavy elements in quasars, a large burst of massive star formation is needed, and as of 2004, much current research is aimed at trying to find these stars. If these
population III stars are found, this will strengthen the Big Bang theory.There also remain small numbers of astrophysicists, including
Y.P. Varshni and Halton Arp, who argue that redshifts in galaxies are not strictly due to the Doppler effect, and that this invalidates the need for the Big Bang. However, these astrophysicists propose no alternative mechanism, rather they rely on their own incredulity to criticize the standard cosmological model. Dark matterDuring the 1970s, observations were made that - assuming that all of the matter within the universe could be seen - created problems for the Big Bang theory, as it seemed to underestimate the amount of deuterium in the universe and lead to a universe that was much more "lumpy" than observed. These problems are resolved if one assumes that most of the matter in the universe is not visible, and this assumption seems to be consistent with observations that suggest that much of the universe consists of dark matter.
The effects that dark matter has on Big Bang calculations generally do not depend on the detailed properties of the dark matter. The main property of dark matter which influences cosmology is whether the dark matter consists of particles that are heavy and hence are moving slowly, thereby creating cold dark matter, or whether it consists of particles that are light and hence are moving quickly, thereby creating hot dark matter, or whether the dark matter consists of ordinary matter which is baryonic matter.If the gravitational attraction of all the matter in the observable horizon is high enough, then it could stop the expansion of the universe, and then reverse it. The universe would then contract, in about the same time as the expansion took. Eventually, all matter and energy would be compressed back into a gravitational singularity. There are theories about what happens after this, but these remain uncertain as the physics of singularities remains in question. Also, the omega point theory suggests that an infinite amount of computational capacity might be available in the finite time before the Crunch.
If the gravitational attraction of all the matter in the observable horizon is just right, then the expansion of the universe will asymptotically approach zero. The temperature of the universe would asymptotically approach a stable value slightly above absolute zero. Entropy would increase, and the end result (with protons decaying) would be similar to the Big Freeze.
These are generally full of technical language, but sometimes with introductions in plain English.
Information of Non-standard cosmology
A non-standard cosmology is a cosmological theory that contradicts the standard model of cosmology. The term has been used since the late 1960s after the discovery of the cosmic microwave background radiation (CMB) in 1965 by Penzias and Wilson. These observations, combined with the theory of big bang nucleosynthesis and other evidence which suggested that the universe evolved, caused most cosmologists to favor the Big Bang theory over the steady state theory. Since around this time, in practice a non-standard cosmology has primarily meant any cosmological theory which questions the fundamental propositions of the Big Bang theory.
The motivation behind much of non-standard cosmology is the fact that to explain current observations within the framework of the big bang, one must include some seemingly ad-hoc assumptions and inelegant additions. For example, in order to make the big bang consistent with current observations, one would need to postulate the existence of some form of dark matter and dark energy and a phase of rapid expansion known as cosmic inflation. Proponents of non-standard cosmologies argue that these additions to the theory lead to an inelegant system which some have compared to the Ptolematic model of the solar system. By investigating and questioning the basic assumptions of the Big Bang theory, non-standard cosmologies attempt to address these issues from a supposedly empirical framework, even though the foundations of non-standard models might clearly contradict those of the Big Bang theory.One point that should be noted is that there is not a single non-standard cosmology. Within the category are many different models which often contradict each other. This is in contrast to standard model of cosmology that is designed to be in concordance with the sum total of all cosmological observations (see Lambda-CDM model). While what is considered the standard model of cosmology as opposed to a standard model of cosmology has changed over the years, the general consensus in the scientific community is that with the advent of precision cosmology, model-making in the field is today more of a parameter fitting exercize rather than complete reinvention. Non-standard cosmologies are promoted by a few generally independent researchers and amateurs who disagree with foundational assumptions and so reject the idea of applying concordance criteria to their models.
In addition, the term standard can be slightly misleading. For example, it is the case that all of standard cosmologies under serious consideration in 2004 contain physics which is outside the realm of the standard model of particle physics and presume the existence of some form of particle, field, or object that has not been observed. Conversely, proponents of some non-standard cosmologies assert that their models contain no physics which has not been observed, and in fact often cite this fact as evidence in favor of their models. Although most astronomers since the 1960s have concluded that observations are best explained by a variation of the big bang model, there have been two periods in which interest in non-standard cosmology increased due to observational data which posed difficulties for the big bang. The first occurred in the late 1970s when there were a number of unsolved problems such as the horizon problem, the flatness problem, and the lack of magnetic monopoles which challenged the models of the big bang then under consideration. These issues were eventually resolved by cosmic inflation in the 1980s which subsequently became part of all future standard cosmologies. The second occurred in the mid-1990s when observations of the ages of globular clusters and the primordial helium abundance showed the potential of seriously challenging the big bang. However by the late 1990s, most astronomers had concluded that these observations did not challenge the big bang and in addition data from COBE and WMAP provided detailed quantitative data which was consistent with standard cosmologies.Non-standard cosmologies minimally challenge one or both of these, usually asserting that one or the other is incorrect.
Alternative models of cosmology that do not challenge the two assertions above are generally lumped together as standard cosmological models, even if they are not universally accepted. For example, the ekpyrotic universe holds that the expansion of the universe began in the collision of two branes in the higher dimensional "bulk" of brane cosmology. Although radical, this cosmology is an extension of, rather than a detractor of, the big bang theory.
Any cosmological theory should be able to explain the near-isotropy of the CMB (Cosmic Microwave Background) and should also be able to explain the micro-Kelvin CMB anisotropies measured in detail by the WMAP mission. Standard models invoke a period of inflation in the early universe, the underlying mechanism, although efforts to associate that period of inflation with a specific physical mechanism have been unfruitful.
Alfven, Lerner and others working within plasma cosmology have claimed that the temperature, isotropy, and non-polarisation of the CMB can be readily explained as the diffusion of galactic radio emission by the magnetic fields of intervening plasma filaments. Electrons travelling along the large, weak magnetic field lines of a galaxy can absorb radio, and re-emit it in a different direction. This scatters the radiation, much as light from the sun is scattered in a dense fog. This can also explain the observed decrease in radio brightness of galaxies relative to their IR luminosity with increasing redshift. Lerner explains that radiation from distant galaxies successively interacts with the magnetic fields of many intervening galaxies, nebulae, supernova remnants and so on, resulting in an isotropic scatter. What Lerner fails to explain is why the electrons should reemit in the best measured blackbody spectrum observed in all of science and how the entire plasma can become thermalized with anisotropic radiation fields.Standard cosmologists also calculate the anisotropies in the CMB and identify a number of features such as peaks and valleys in its power spectrum which correspond to cosmological quantities. WMAP has been especially fruitful in providing a goldmine of data that is interpreted easily by the standard cosmological models. The inability thus far of plasma cosmologies to come up with a theory that replicates these features in detail has led most astrophysicists to dismiss them. There was recently some excitement on the part of certain plasma cosmology adherents over an analysis of WMAP results by researchers at the University of Durham. This analysis proported to show certain micro-Kelvin anisotropies in the WMAP data correspond to the locations of local galactic clusters and superclusters. This association was just as predicted by the Sunyaev-Zeldovich effect and was the purpose of the investigation. However, some fans of Eric Lerner claim that his model predicted similar types of associations.
A second alternative explanation, favoured by Steady State theorists, is that the intergalactic medium contains microscopic iron dust particles or whiskers, which can also scatter radio in the same manner to produce an isotropic CMB. However, observational evidence for the existence of these iron particles is yet to appear. Either of these explanations could potentially free other alternative cosmological models such as general time dilation, steady state models, and so on from the need to explain the isotropy of the CMB, because they transform it into a local effect rather than a cosmological feature.General

Is it possible that the Society is now beginning to get more than a little concerned over how many are leaving the Organization.
Perhaps economics is a factor, as each JW probably represents an important financial contribution or consideration over time. For example, banks spend a great deal of time and effort and money "recruiting" new customers, because they know statistically that each new account represents something like about $500 a year in new business (even if it's only service charges on a chequing or savings account).
Could it also be that the Society is thinking twice about their harsh "shunning policy", and what we are now witnessing is an introductory strategy to ease the R & F into an eventual policy of greater tolerance?

or do our observations of nature show things that a theory says are impossible?
gamow had argued that the stars' temperatures are too low to create elements heavier than helium.
I thought it would be good to add an article that is in favour of the Big Bang Theory. This is just a way to not lose sight of the fact that a great many scientists DO support Big Bang, and have many reasons for doing so. It would not be very fair to present only the opposing views, and leave the evidences for Big Bang out of the conversation.
Can you name 10 things that contradict Big Bang Theory?
This is a completely fair question, but actually a difficult one to answer.
The 'problem' is that there are a great many contingencies that have to come together to generate a severe contradiction. That's how good Big Bang theory seems to be. It is like asking for 10 things that contradict quantum mechanics, or our current scientific explanation for why we have seasons. Here is my list of the 'weak' points of Big Bang cosmology:
1...
Big Bang theory is based on general relativity. General relativity predicts how gravity and space-time operate. If it is found that GR is incomplete as a classical theory, then Big Bang could be doomed because all current cosmological solutions or 'models' are based on solving Einstein's original, general relativistic formula for gravity. So far, 6 tests have been performed and compared with GR predictions and it has been found that Einstein's original version remains the simplest version of GR. So far, there is NO contradiction on this basic point.
2...
A basic feature of Big Bang theory is that the universe has a specific age given its expansion rate. As you know, the ages estimated for the oldest known stars are between 12 and 17 billion years, however if the Hubble Space Telescope estimates for the local expansion rate are correct, an age for the universe closer to 12 billion years is predicted. There are only two known ways to save this disagreement, either the galaxies used to measure 'Hubble's constant' are too local to measure the true, slower expansion rate, or there is a new cosmological 'anti-gravity' force present produced by the so-called cosmological constant. If it should come to pass that the expansion speed for the most distant galaxies holds fast to 60 - 65 kilometers/sec/megaparsecs AND the ages of stars holds to 12-17 billion years AND observations can eliminate the cosmological constant as being negligible THEN Big Bang theory is in severe trouble since you cannot have stars older than the Big Bang. In 2002, the NASA WMAP satellite confirmed what astronomers have been discovering since about 1998. The universe is accelerating its expansion and its current age is 13.7 billion years, with an uncertainty of about 200 million years. Also, 73% of the energy in the cosmos is Dark Energy. This neatly resolved a major problem for Big Bang theory. Currently, there is no contradiction.3...
If some new processes is discovered that can REDUCE the cosmological abundance of deuterium, then one could have the situation that Big Bang theory predicts MORE deuterium than can be accommodated by the expansion rate and baryonic density of the universe. This would be a severe contradiction with Big Bang nucleosynthesis calculations which already give excellent agreement between deuterium and plausible expansion rates today. Currently, the D/H ratios for pre-stellar objects show no contradiction with Big Bang calculations.4...
If a new explanation for the cosmological redshift is discovered, the existing redshift which leads to plausible solutions from GR, would be over estimating the cosmological effects which are already consistent with other types of observations. No known explanations not in line with Big Bang theory are available.5...
If a new mechanism is found for producing a smooth cosmic background radiation, then the uniformity of the measured cosmic background would not be explained by Big Bang theory, or plausible extensions of it. No examples are known.6...
If a new, long-range force is discovered, then Big Bang theory will have been incompletely describing the dynamics of the expansion process. This could work either in favor of Big Bang, or contradict it depending on the strength of this 'fifth force'. The WMAP observations show that such a force exists and is of the magnitude and sign to explain cosmological accelerated expansion.7...
If dark matter is found to be baryonic, and exceeds the amount of baryonic matter upon which the Big Bang nucleosynthesis calculations are based, then there is something severely wrong with Big Bang theory predictions during the first 10 minutes after the Big Bang...a time period that is recognized as a 'piece of cake' for physics because of its simplicity. No such disagreements have been verified.8...
If galaxies are found to have formed earlier than the first million years after the Big Bang, this would conflict with Big Bang theory and the Inflationary extension of it because the predicted strength of the seed fluctuations at galactic scale would be stronger than the theory allows. Currently not an observation we can make until the Next Generation Space Telescope begins operating in 2011.9...
If something like Inflationary Big Bang theory is not vindicated, then there will be no simple solution to the problem of how the cosmic background radiation can be so smooth and at the same temperature at scales larger than a degree, since at earlier times in the expansion, regions of the sky farther apart than this would not have been in communication to coordinate their temperatures so exactly. No 'crises' with inflation have been identified to date.10...
If 'dark matter' is discovered and found to have undergone a complex history during the nucleosynthesis epoch, there might be the opportunity for this dynamically important component to have affected the Big Bang abundance calculations, which currently give acceptable ratios for helium and deuterium abundances. Any dark matter perturbation could make these predictions in error. Currently we cannot detect Dark Matter in order to study it.So, this is my list. It is not comprehensive. I want to warn you that these are weaknesses, but currently NONE have been established from the data at hand to be actual problems for Big Bang theory. This makes Big Bang theory a falsifiable theory of the highest caliber, and still makes it the leading candidate for THE theory of how our universe works. Thus far, Big Bang theory or versions of it, have survived
a number of important tests . Whether it continues with this track record for the next few decades, we will have to await the outcomes of some important, on-going and planned experiments.

Ask the AstronomerRod P.Can you list 10 or more observational facts supporting Big Bang Theory?
Sure!
1.... The universe is expanding.
2.... There exists a cosmic background radiation field detectable at microwave frequencies.
3.... The cosmic microwave background field is measurably isotropic to better than a few parts in 100,000 after compensation is made for the relativistic Doppler effect caused by Earth/Sun/Milky Way motion.
4.... The cosmic microwave background radiation field is precisely that of a black body.
5.... The cosmic microwave background radiation field has a temperature of 2.7 K.
6.... There does exist a universal abundance ratio of helium to hydrogen consistent with the current expansion rate and cosmic background temperature.
7.... The cosmological abundance of deuterium relative to hydrogen and helium is consistent with the levels expected given the current expansion rate and density.
8.... There are only three families of neutrinos.
9.... The night sky is not as bright as the surface of the Sun.
10... The cosmic background radiation field is slightly lumpy at a level of one part in 100,000 to 1,000,000.
11... There are no objects that have ages indisputably greater than the expansion age of the universe.
12... There are about 10,000,000,000 photons in the cosmic background radiation field for every proton and neutron of matter.
13... The degree of galaxy clustering observed is consistent with an expanding universe with a finite age less than 20 billion years.
14... There are no elements heavier than lithium which have a universal abundance ratio.
15... The universe was once opaque to its own radiation.
16... The universe is now dominated exclusively by matter and not a mixture of matter and anti-matter.
I should point out that, although some rival theories have proposed alternate explanations to a few of these observations, there are no rivals that provide a simple explanation for all of these remarkable observations. What could be simpler than a universe expanding from a hot, dense state to the present cool, rarified one with all of the above features emerging! No new physics is required, no mysterious forces, just gravity and hot matter doing their thing over billions of years!

jehovahs mother chose death before baby
a dying mother refused a life-saving blood transfusion despite nurses holding up her new-born son in a desperate attempt attempt to get her to change her mind.
kilroy2,
Well, I agree with your sentiments about not feeling sorry for the choices a person makes as an adult, and therefore must be held accountable for the consequences of those choices.
However, one of the things that bothers me here, is the question of how much brain-washing has gone on with these JW's to the point that they have been conditioned to live in accordance with this fanaticism.
The second, and most important issue in my mind here, is the fact that the little baby boy had no choice in that matter. He has now lost a "mother" because of her choice. Does he deserve such a fate, expecially since he had no say in the matter? That is what's is so unfair and unjust here.

Hi Danny,
Nice to see you back, and I hope you are feeling better now.
Just a quick note:
I do not kow if you mean this, but relativity does not depend on the big bang. There can be a other explanation of the universe, and still have relativity.
Yes, I agree with you that Relativity does not depend on the Big Bang. And yes, Relativity does fit into other models of the Universe.

johnny_was_good,
Interesting.
Was the speaker suggesting that the members of the JW audience therefore start contacting all those who were disfellowshipped, or who had disassociated themselves?
Who was he addressing his message to? Was he hoping there were Disassociated or Disfellowshipped people in the audience, and so he was encouraging them to come back?
Just asking.
Rod P.
running out of ideas.
anyone have some good points against 'new light'?
as you all know, on one hand the wt says to look back at old issues (however i think that issue itself is 'old') but if you do look back at old issues and point out contradictions, then of course it is 'old', out of date, etc... "that is the beauty of the org, things are revealed blah, blah,.....you know the drill.
Well, what I want to know is:
What was once taught as "Truth" (Old Light) was also in contradiction of what the theologians of wicked old Christendom were teaching.
Then along the way, the GB announces a "New Light" about the "Old Truth". Only problem is, now this "New Truth" is suddenly in harmony with what the theologians from wicked old Christendom have been teaching all along.
Of course, Christendom is regarded as part of the world-wide empire of false religion "Babylon the Great", with Satan the Devil as its head. The clergy are, therefore the spokespersons for this evil empire that is going to be destroyed in the Big "A".
So how is it that Satan's representatives are in possession of this "New Truth" years in advance of Jehovah's Faithful and Discreet Slave, the Governing Body?
A case in point: Back in the early 1960's there was a new teaching about the "Superior Authorities" or "Higher Powers" (KJV). The JW's were always taught that the "Higher Powers" were "Jehovah God and Christ Jesus" who they owed their subjection to, and not the "earthly governments and rulers" as taught by Christendom. Back in the 1940's (World War II) a lot of male JW's went to jail for precisely this interpretation of the scriptures. The courts brought in some Biblical scholars (theologians) to convince these JW's that they were basing their argument on erroneous interpretation of the scriptures. But they would have nothing to do with it, as they, of course, could not trust these wicked Pharasaical Theologians. And so they went to jail.
Then years later, further research by the FDS caused them to come to the conclusion that those passages of scripture where it speaks of these "Higher Powers" or "Superior Authorities", had to be understood as being the "earthly governments and rulers". (Exactly what the theologians have been saying all along.) Then they went on to say that notwithstanding this new interpretation, nevertheless, this was a "relative subjection", and "where a law of man contradicts a law of God, then we must obey God as ruler rather than men." However, this is a principle that most theologians and biblical scholars have taught and believed in all along. Nobody is arguing that essential principle.
What we are arguing about here is the fact that they have been defending a certain principle based on an erroneous interpretation of scripture. And Satan has inspired his wicked and evil servants of the "correct truth" years in advance of God's Sole Channel of Communication on the Earth between God and Man, the Faithful and Discreet Slave/Governing Body.
So tell me, what's wrong with this picture?
