Watch some clips from astronauts on the ISS, they too move slow inside the ISS. The reason might be, that every move you make has an effekt, you raise your right arm and your whole body start turn in the opposite direction. The faster you move the more prominent this gets and you start to float and turn out of control and you dont want that inside a space Station...

Well, this one dude called Stephen Hawking did some maths and had some things to say about this:

Doesn't actually prove or disprove it, but he did try to answer the question

We don't know. No one here knows. These are concepts we can't comprehend. A lot of what is happening here is VERY well educated science fiction.

Anyone who gives any other explanation beyond we don't know is really just taking a wildly educated guess.

We can't answer this question.

Yeah at first I was bummed to hear it had a deorbit date, but it looks like the new thing is all the spacefaring nations are going to start building their own space stations. The US is looking at several solutions and may do more than one of them at once. It sucks that it's time has come, but the biggest achievement of the ISS was building it in the first place. We all worked together and learned a lot, now the next phase is going to be ground-up rebuilds using everything we learned. It's still progress!

Also unless someone else builds a Starship they're going to have a really hard time keeping up with the US in the future.

Honestly I don't have a sure answer to that question. But I can guess.

Based soley on my own very limited knowledge, theoretically if the big bang happened over and over again infinite times, in a completely random fashion every time, you could eventually result in one where every particle ended up in the exact same place and in the exact same state, which could lead to the same nitrogen bonds forming, etc. and the events of this universe would perfectly repeat themselves.

The universe does not go for forever in terms of time, it goes for forever in terms of space.

The universe is expanding infinitely in the sense that everything is getting further and further apart from each other. Eventually, things will get so incredibly far apart that the space between each object will make it impossible for them to interact. Every star will go out and the universe will go dark, and realistically, nothing will ever happen again.

Many theorize that this will precede another big bang, but there is not enough solid evidence to support or disprove this.

You have to make a few assumptions to get to "yes". Not only is the universe infinite, but so too is the proliferation of matter, the density and variety, etc. Everywhere has to have had the same amount of "when" too, and who knows how that works or whether the universe exists as a static infinity or a growing one. Our sphere of observation would indicate the former, but we can't really say what fraction of the universe, if it's anything other than infinite, we might see.

But if all of that holds true, then no matter how unlikely this exact configuration of not only matter but also events is to reoccur, it does so an infinite number of times. No matter what the number is, the one in however many trillions of trillions chance of it happening, the opportunity to do so remains "infinity", and that's what the whole expression about monkeys and type-writers means.

It's not really something do we do well with, conceptually. Our brains don't really do "infinity", it was at no point a factor in our evolution and trying to imagine it is probably only something widely attempted over the last two hundred years, we're not equipped to do it. The math makes sense, but the imagination can't follow that road. I mean, unless you're Einstein or Newton or some shit, seems like they did exactly that sort of thing.
