Just figured I'd plug a link: the
<a href="http://www.superstringtheory.com" target="_blank">www.superstringtheory.com</a>
site mentioned in another thread has some information that deals with the Big Bang and cosmology in general.

It would seem to me that it is necessary for something to be CAUSALLY prior to the big bang even if it were not TEMPORALLY prior. Something must have caused the Big Bang, even if that something (be it God or a some process) did not exist in time.

Also, I am not entirely convinced that Hawking's defintion of time starting at the big bang holds water IF there is something other than the universe. Perhaps I am totally off base here, but I thought that the notion that time was created at the big bang is dependant on the fact that time is dependant on spatial dimensions, matter, movement, and the direction of entropy, all created at the big bang. That's fine if this universe were all that there is, but what if it isn't? Why couldn't there be matter, spatial dimensions, and all the rest of it in some other universe or other place, which could have therefore had it's own time and therefore be temporally prior to the big bang (and possibly causatively prior)?

Perhaps he arrived at a definition of time through some mathematical means I am not aware of and I am simply terribly confusing his argument right now.

I like the theory that whenever a star collapses into a black hole a universe is created, we are inside a black hole. Now I can't remeber whose theory this was, it had to due with how measurements become meaningless or else in fact reverse at super small levels. The infinitely small replaces the infinitely large. Or something to that effect.

crownboy asks: "What was there before the "Big Bang"?

That should be obvious, the big fire cracker of course.

When we talk of the Big Bang setting time into motion lets remember that time itself might NOT even exist....Several "Big Brains" in science have shown that this is plausable..<a href="http://homepage.ntlworld.com/anthony.campbell1/bookreviews/r/barbour.html" target="_blank">The End of time By Julian Barbour</a>

Hi guys, I feel that it is quite meaningless to consider the small picture of our universe only. As far as reality is concerned, unobserved multiverse and other undiscovered dimensional spacetime may give us a far larger picture than the current one that we are discussing. In other words, its like talking about the creation of Earth without reference to the universe on the whole.
Personally, I tend to believe that our universe isn't alone in the vast spacetime. Even if the physicists managed to discover the mechanism working behind the big bang, we will still have a long way to go.

my first claim is more logical reasoning based on what's his names idea that time and space started at the big bang. the second thing i said is someone elses theory (that i happen to aggree with currently), who's name i cant remember. it's to early to think.
