First off, this thread has been most enlightening for me. I have a few questions similar to Ringokid's. My questions are based on current ideas on the matter, not that anyone 'knows' the answers exactly. Opinions will do.
Did space start expanding from a point? And was everything, particles and such, 'created' instantly afterwards?
This also brings to mind that space, three dimensions, if expanding, should have a center point. Is space able to expand because it is infinite?
One more. How could all of the dense matter be 'created' simultaneously? I guess I have a hard time getting past it starting at a point; similar, maybe, to quantum fluctuations allowing particles to appear at some place near each other and then be annihilated.
