Not talking a few decades into the future.
Not a few centuries.
Not even a few millennia.
I'm talking a minimum of a few hundred thousand years ahead.
What are some of the "extremely far ahead" sci-fi that you have read or at least know of?
Point of reference: anything on par with, but preferably farther ahead of, the future timeline of H.G.Wells' classic tale THE TIME MACHINE.
Bonus points if no actual time travel occurs in the story.
Really curious to see if there are any recommendations with a setting so far removed from our own.
