Isn't this exciting stuff cantleave? I saw it on the NASA site.
They were saying that they can now return to some more simple theories and get rid of some of the more complex ones. THATs always a good thing...LOL
QC thanks for the videos...I'm gonna watch them later.
Bookmarked for later I love this stuff

They were saying... return to some more simple theories and get rid of some of the more complex ones.
The Standard Model is not robust enough to explain mathematically dark holes, dark energy and dark matter, etc. So in 1984 physicist (John Schwarz and Michael Green) showed that String Theory is a player. It theorizes that everything material is made of strings, the final smallest particles. Hence, everything and everybody is part of a cosmic oscillating symphony. What's promising is the mathematics has the simplicity elegance hallmark of Relativity (Einstein) and Electro-Magnetism (Maxwell). But it's very, very speculative with its multiverse (parallel universe) notion.....hmmm.
I was just noticing a pattern in "new light" or "new understanding" ....science always changing, JW always changing...it's like they both are a wait and see situation...I wasn't questioning the truth of either one...just the pattern. I'm a this is like that kind of gal and I have my own theories...they amuse me! :) I imagine JW fancy themselves as scientists of interpretation of the bible...they form a theory, back it up with "evidence" and then form a conclusion, then "new evidence" is "seen" and then a new conclusion is made...it's like kids playing dress up...in a way!

I've tried my hardest to understand string theory...I sort of do, but not really.
But we do know there was a BEGINNING, a situation before when nothing material exists, including time. Hmmm.....
How do you know this?
@lriddle80
science always changing, JW always changing...Computers, internet, and cell phones have instant information about everything all the time. So changes come fast because information comes fast. Dan 12:4 says in "time of the end many will rush around,
while knowledge increases"; so this fast pace info must mean we are in the time of the end. :o) Look at all the good info here at JWN. Have you read Gentile Time Reconsidered? Download it here, item #9

understand string theory...I sort of do, but not really.Wait a bit on String Theory. Follow the Higgs boson regular updates. They're trying to figure out what the spin is, 0 or 2. I'll keep you posted.
@EP
How do you know this?That's what the Big Bang is, the beginning of the universe which includes time. That's definitive. Where have you been?
This will get you up to speed:

CERN now knows we have a (not the) Higgs boson and the spin is 0. More details are needed to say whether it fits the Standard Model or a more exotic model theory. If it fits the Standard model only, this means there is only one Higgs boson in the universe.
Next focused report is to see if this Higgs discovery sheds light on antimatter.
Spin is the amount of rotation an object has, taking into account its mass and shape. This is also known as an object's angular momentum. Objects as large as a planet or as small as a photon can have the property of spin. Spin is also the reason we can watch movies in 3D.
All objects have some amount of angular momentum. A spinning coin has a little angular momentum; the moon orbiting the earth has a lot. Like energy, angular momentum is a conserved quantity: The total amount is constant, though it can flow from one object to another. When a spinning figure skater contracts her arms and rotates faster, her angular momentum is unchanged because a narrow object rotating quickly has the same angular momentum as a wide object rotating slowly.
Particles, as far as we know, are infinitesimal points of zero size. Yet they have measurable amounts of angular momentum. Does the concept of rotation even make sense for a featureless speck? Angular momentum seems to be a more foundational concept than rotation itself.
The angular momentum, or spin, of a single particle is restricted in strange ways. It can have only an certain values, and not all values are allowed for all particles. Electrons and quarks (particles of matter) can have a spin of -1/2 or +1/2; photons (particles of light) can have a spin of -1 or +1; and Higgs bosons must have a spin of 0.
Though particle spins are tiny, they have an impact on our everyday world. The spin property of photons allows us to create 3D movies. A movie theater simultaneously projects two images, one with positive-spin photons and the other with negative-spin photons. One side of a pair of 3D glasses filters out the positive-spin photons, and the other filters out the negative-spin photons. We therefore see one image with each eye. Our brains combine them to create the illusion of depth.
It is fortunate biology that humans have as many eyes as photons have spin states. -Jim Pivarski, Fermilab
