How does anyone know matter didn't always exist? (page 2)

Does it really matter?

Oh sorry about that attempt at humour.

I believe the universe has always existed in it's present form from it's creation by God, and that all this "background radiation" nonsense are planted by God to fool scientists. The Dinosaur bones are the same, there were no "dinosaurs" God created these bones and put them in thier present place when he created the world 6000 years ago. Holy COW people, don't you see it?

yes, and there is no gravity, Earth sucks.

Nathan,

Thanks, I knew someone would understand!

Perhaps you might enjoy reading a bit of information about Cosmology and see for yourself the thinking of scientists about the origin of the universe.

Here are a few links to get you started:

Now as for your use of the word singularity, I'm not quite sure where you are coming from. Here is the accepted definition of this word as per several dictionaries:

(snip)
Main Entry: sin·gu·lar·i·ty
Pronunciation: "si[ng]-gy&-'lar-&-tE
Function: noun
Inflected Form(s): plural -ties

1 : something that is singular : as a : a separate unit b : unusual or distinctive manner or behavior : PECULIARITY
2 : the quality or state of being singular
3 : a point at which the derivative of a given function of a complex variable does not exist but every neighborhood of which contains points for which the derivative exists
4 : a point or region of infinite mass density at which space and time are infinitely distorted by gravitational forces and which is held to be the final state of matter falling into a black hole

(end snip)

Thus, if you are addressing the last definition and suggesting that what existed before the big bang was a giant black hole you might be making reference to an older theory of cosmology which was called the oscillating universe where the universe explodes, contracts, explodes again indefinitely. There is enough evidence now to know this isn't what is happening to our universe. There is not enough matter in our universe to slow down the inflation of the universe and at some point in the distant future, the whole universe will be spread out and eventually die from heat death and not contract again.

Yes, there is physical and observational evidence for black holes in case you are wondering. This is a great shot of one by the Hubble Space telescope of a giant black hole in another galaxy. There is a huge one in our own glaxay gobbling up stars every now and then as well.

Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052

Mind,
Are you absolutly sure of this?:

There is not enough matter in our universe to slow down the inflation of the universe and at some point in the distant future, the whole universe will be spread out and eventually die from heat death and not contract again.

How do you even know there is not enough matter in the universe?
Do you even have any idea of how much matter is in the universe?

If someone lived a trillion X longer than you, and had a billion X more reasoning ability would he come to the same conclusions as you?

OK, DW, I get it - you're doing a Monty Python sketch, aren't you?

"This isn't arguments, this is simply negation."

No it isn't!

There! You've done it again!

I have NOT!

D. Wiltshire asked me...
Are you absolutly sure of this?:

Are you playing Devil's advocate and want to question everything or are you looking for information about an issue important to you?

In science, very few things are 100% sure. We use varying degrees of probability for looking at the validity of theories. For instance, there is a very tiny probability that Fred Hall is actually an alien from a distant galaxy. We cannot say with 100% assurance that this is not the case. It is however very unlikely, considering the difficulties of this actually happening. So, very few things are indisputable. You look for and work with a trail of evidence. When the evidence suggests something else is more reasonable, you look in that direction to see if it matches the collective knowledge you have already assembled.

Mr Wiltshire,

Are you fair Dinkum? These things are very basic science. If you go to any good bookshop you'll find these questions thoroughly answered in popular science books (even star atlas will tell you all you need too know about red snifts, the dopler deffect, the humble space telescope, the minky way, quandong physics, einsteins relatives theory's etc...) Rest assured Venus and Mars are alright tonight.

Ever watched an episode of Red Dwarf? Go seek .. the answer is out there at your local video library.
