If the universe is finite, then what does it end to? One assumes the big bang occurred at a single point, and the expansion reaches a certain limit and then contracts...what is beyond the limits of that expansion? Is it then the mobius strip theory of space?
What is beyond the limits is outside of the universe and perception. It may be truly nothing. Maybe it’s everything. But what ever it is, it impossible to know from here. Here we be finite.
Which must mean there is a single point in the Universe from which everything is moving away.
For a long time science declared that point was Earth.
Now they find that everything is moving in different directions at different speeds. So they claim that it's space itself that is expanding and everything is moving away from each other while moving in random other directions including towards each other with spectacular results when crashing together.
HEAT DEATH (entropy) : The theory that all the energy was created at the big bang, and it slowly burns out over time. Yet as old stars die out, new stars are born.
So, the facts don't fit the theory, at all.
