2 Interesting facts.
In 5 Billion years the rate of Galaxies moving apart from each other will reach a point at which most Galaxies will be out of view of each other. So if any future civilization is ever created they will never know of other Galaxies.
Also, in roughly 1,000,000,000,000 Years (1 Trillion), the Galaxy will have run out the Hydrogen, as a result star creation will halt. And the remaining stars will begin trickling out of existence.
the math adds up very nicely in this description. all debts are paid.
gravity has an infinite range, therefore as the galaxies expand exponentially they will collapse upon themselves exponentially. Meaning, when the universe begins to retract, the diameter of the universe will shrink slowly, than collapse faster as it grows more... dense
Except most physicists think that won't ever happen and the universe will continue to expand forever and eventually undergo heat death.
if the universe expands forever how does a big bang happen in the first place?
it would suggest there is time before a big bang, and the math becomes complicated.
