stars will be farther apart in the sky and eventually as the universe expands, you won't see anything except pitch black.

I once went to a Wikipedia page with a title like "the far timeline of the universe" or something. Putting it poetically - I think it was that the stars go out on earth in ~100b years.

Timeline of the far future

100–150 billion The Universe's expansion causes all galaxies beyond the former Local Group to disappear beyond the cosmic light horizon, removing them from the observable universe.

I guess Windows 10^87^ won't allow you to reconnect to Local Group unless you have Windows 10^87^ Pro.

The far future is truly Lovecraftian and hard to fathom. Eventually star formation will cease, most of the timespan of the universe will be the "dark era" where black holes slowly evaporate due to Hawking Radiation. Then there will only be light, and when there is only light then time itself ceases to exist as a meaningful construct. Space, too, perhaps. Then there is an alternative, even longer ending, if it's possible for light itself to decay.
