By this time in the future I hope we have worked out wormholes.

Highly unlikely. Unless wormholes are setup with strange restrictive configurations they allow sending messages back in time, without needing any new physics. Once you have a wormhole, if you use gravity to accelerate one of the ends away then bring it back near the other end, they will have a time difference, due to general relativity. If you bring them close enough, that time difference will be greater than it take…

This goes together nicely with the Aestivation Hypothesis ( https://arxiv.org/abs/1705.03394 ). If a civilisation puts itself on hold for a trillion years, just waiting around doing nothing, then when it wakes up the universe is much colder and it can do computations 10^30 times more efficiently. If the civilization consists of minds running on computers then they've increased their own lifespans by the same factor.

Earlier quoted context omitted.

Even in a trillion years, a star won't burn up so much of its energy that less than 10^-30 of it remains. So the wait is worth it.

I'd argue the opposite: it only takes one non-hibernating species out to dominate and it will hunt down every sleeping civilizations data center and annihilate them - so that they remain the most dominant species. Such a "hibernation data center" must thus be the most well guarded / hidden place in the galaxy...

Isaac Arthur made a compendium called Civilizations at the End of Time [1] that goes into this territory. This guy, in my opinion, goes above and beyond even your typical hard scifi. Can't recommend highly enough. [1] https://www.youtube.com/watch?v=p58yFf7aZsM&list=PLIIOUpOge0...

I just gave this a go. It's amazing, thank you for putting it on my radar. At first his speech impediment makes it harder to follow, but 5 minutes in you're used to it and you're just riveted by the content and the clear communication style. This is quality stuff.
