How can i define Time? I tried to define Time but could not do it without using words like "moments" which in itself means time. Can someone give a definition of Time ???

I called their NASA AMES research center to get information for my master's thesis and they had such a BAD attitude with me! And for no reason at all. =(

Why is that? Am I taking precious moments away from their busy schedules?

I'm not talking about nearby stars or galaxies. Light speed and stuff, I understand. It takes time for light to travel the distance. I'm talking about billions of light years here all the way to when the Universe was first created.

According to the Big Bang, everything originated from a single point in the Universe and spread out from there. So unless we've been spreading at the speed of light (not possible) the light that originated from the Big Bang already passed us a long time ago. Why is the observable universe 14.5 billion light years? (approximate age of the Universe, could be wrong on that number) The diameter of the universe can't be that big unless we've been spreading at least half the speed of light since the Big Bang.

Shouldn't there be a limit on how far back in time we can see? I mean since we have a calculation as to how fast the universe is expanding and the age of the universe, it should be fairly simple to calculate how far back in time we can see.

Is space something just like a distance between 2 objects or is it something more substantial?

(follow this link to a site that talks about A.E's last press conference in 1955)

and that in fact it was a greek scientist called Karathodoris several years before it came into light. Not only that, Einstain in fact asked the help of Karathodoris (his teacher) to explain the theory to him so he can answer the difficult questions that the scientific community were asking him.
