And our local galactic cluster is heading towards something ominous called the Great Attractor. It’s direction is hidden by the horizon of the Milky Way, but it is most likely another larger cluster of galaxies
Then you should know that you can’t just get a degree from reading books at the library, right? You can teach yourself everything, but that doesn’t mean society will recognize it unless you build your own business from the ground up and earn an “honorary” degree.
And if you can afford to do that, you were born with a silver spoon in your mouth.
Seeing as the heat death of the universe occurs once black holes have stopped emitting Hawking radiation, and BH’s life spans are tied to their mass, could a (very, very advanced) civilisation bring two or more together? Assuming nobody’s succumbed to proton decay before then, of course....
I believe there have been multiple sci-fi stories written about such concepts. It would go to assume that any civilization still around in 10^43 years from now will have no choice but to live around black holes while harnessing their rotational energy. My current favorite series, Xeelee Sequence by Stephen Baxter, explores some possible endings of life in the long-term life cycle of the universe. There is also the final book of the Three Body Problem, which if I remember correctly, shows civilizations in pocket universes around black holes.
There is a YouTube video you may want to watch by Isaac Arthur. It mentions the possibility of combining black holes to elongate their life, and I won’t spoil the final answer for you. But like always, entropy prevails.
You’re spot on ;) Xeelee Sequence is a collection of a bunch of books, loosely held together by the fact that they all take place in the same universe propagated with all possible forms of life. This is a story where there were entire civilizations rising and falling during the first pico-seconds of the Big Bang.

Im a nurse and most nurses seem to agree 2 years is the mark when you become proficient....
Could, in theory, we merge black holes to prolong the life of the universe?
