I assume you read the wiki page I posted?
"... space itself is expanding, so we can actually detect light from objects that were once close, but are now up to around 45.7 billion light years away (rather than up to 13.799 billion light years away as might be expected)"

In that scenerio a billion years from now we won't even see what we see today.
But the rim of the observable universe of today will be lost outside our reach, whatever ingenious instruments 'we' will use.

Naturally this will be many eons after our solar system has disappeared and Andromeda and the Milky Way have collided and formed a new galaxy and that galaxy has formed yet another galaxy with a new neighbouring galaxy etc. etc. etc.

That'll be the day... 😉

That is, if it even happens.

It would surely be a magnificent view! 🙂

Does measurements of length have any sense inside a black hole, because the spatial dimensions are so curled up?

Some analysis of humans going interstellar shows humans won't last too long no matter how far away from Earth we establish colonies, 10,000 light years, 10 light years, their studies say we go extinct anyway.
They say teenagers consider themselves immortal but it seems to me the human race considers itself to be immortal.
Tell that to the dinosaurs. Sure they are around today, they are called chickens🙂
My guess is if the big one was on a collision course with Earth humans would not be able to deflect it very far away anyway no matter how many H bombs we through at it.
For one thing, the ejecta from such bombing would just continue on its merry way hitting Earth in smaller doses but probably overall just as destructive.

The fate of the universe - whether it's the big rip or something else - is entirely unrelated to the (lack of) existence of humanity.
