Woah, that’s crazy to think about. So it’d like get smaller?

Theorists have it that it’ll crunch down to a single point in the same way the Big Bang occurred, or something like it. This used to be a very popular theory but I guess over the years many astrophysicists have gone on to ponder other possibilities, but I’m not intelligent enough to understand them lol

It depends, and currently we can't measure it with enough accuracy.

Most of the scientists thinks a big chill will happen (the universe will be more could from time to time).

I read more, it could be, when the temperature is more next to 0K also atoms will disintegrate into photons and electrons.

Just for clarity, when you wrote 0K you meant 0 kelvin?

Yes.

And you know the 2. Law of thermodynamics. So atoms will lose their energy and disintegrate after some times.

That makes the whole “Big Chill” a lot more clear now. It makes sense that it’d be more plausible too

The big bang/crunch seems to make the most sense. It kinda provides an answer to why we exist. This could be our trillionth life and we would never know it.

No, the distance between objects in stellar will be smaller. The expansion or the opposite doesn't matters a lot for us.

Currently the room between all objects increase, also between sun and earth. But the gravity can easily hold it together.
