The entropy of systems

GD, So you see the BB repeating every trillion years or so? All the stuff returns to the point where the BB began?

Sorry John, but there are "stop signs" out there:

For the Earth, it is the Sun.
For the solar system, it is the center of the galaxy.
For our galaxy, it is the Virgo cluster and so on...

For all motion there is a starting point and a destination.

You really think that space actually had a beginning? Oh, and before space what was there? I will leave you to imagine what ever you like, but before I go I will say this---It is impossible that there was a starting point to this or any Universe because there is a continuum and it is eternal. John

Hi Jim

Yes I think the Big bang repeats itself, but who knows where this will be: matter seems to move towards the most massive bodies in the universe.

GD, OK so I think quite different about this stuff. Anyway, how do you date the BB? Do you have the same figure of ~14bya that the powers to be concur about? If the universe get to where it now in 14by and ~10by more is needed to get to the point where all the matter in the universe is conpacted into 50,000 points billions of light years apart when it the tipping point reached that ends the expansion of the universe?

Hello Jim,

As John says: emptiness of space goes in all directions. The only thing though: matter doesn't. (a galaxy will not stop and change direction).

If you agree that galaxies form clusters, and that clusters form super clusters, then what mechanism replenishes the universe with new galaxies? (that are not in clusters)
(maybe this question should be addressed to John)
