   Johm Brunner's The Crucible of Time. There are only aliens in that book, even if the aliens behave quite humanly.

   https://www.researchgate.net/publication/253117230_Science_F... - which may or may not have specific items in it that you're after, but they are on the harder side of science fiction within the topic.

   I'd also suggest Crucible of Time by John Brunner, while it doesn't have black holes it does have an astronomical time pressure to it.

   Flux is part of Stephen Baxter's Xeelee Sequence and again has an astronomical pressure. I'm gonna point out that this particular story has a lot of plot detained on Wikipedia with spoilers so... go there realizing that.

   Continuing with Baxter and astronomical pressure... Raft (the first book of the Xeelee Sequence).

   An honorable mention in this is another of the great Bs in science fiction his Gregory Before with the Galactic Center Saga... though it lacks the the same astronomical pressures that the other stories I've mentioned have.

   When I was a kid I remember imagining that the dinosaurs managed to create an advanced civilization, reaching the moon, creating cities, tried to harvest asteroids but accidentally wiped themselves out after a major mistake, eliminating the evidence for their civilization in the process.

   This was after reading The Crucible of Time by Brunner (one of my favourite books)
