Gian Posted April 1 Share Posted April 1 I read that by about the year AD10¹⁴ the last stars will be dead, so no more light in the universe, and the universe will leave the stelliferous era and enter the dark degenerate era. The universe will have evaporated away altogether by AD10¹⁰⁰ If species are still around in the year 10¹⁴, I assume life will no longer be possible with no more light. If so, will it in theory be possible for spectacularly advanced species to repair, prolong or create new stars and thus prolong the stelliferous era? Not indefinitely of course, but for alot longer?

J.C.MacSwell Posted April 1 Share Posted April 1 According to the second law of thermodynamics, assuming it holds for the universe as a whole...No. As per Ginsberg...https://en.wikipedia.org/wiki/Ginsberg's_theorem You can't win...you can't break even...you can't get out of the game... You can however, lose efficiently...but not that efficiently. 1 Link to comment Share on other sites More sharing options...
Gian Posted April 1 Author Share Posted April 1 JC MACSWELL So after 10¹⁴ years, that's it. No more life? GIAN🙂 Link to comment Share on other sites More sharing options...

GIAN🙂 I doubt that assertion can be made with 100% certainty... Possibly you can say that for life as we know it but... life finds a way!

GIAN🙂 That's a pretty long time, and I'm assuming it's correct for the sake of argument and that your suggestion to extend is based on technologically creating new replacement stars also...but stars are a pretty inefficient way to go, even if corralling bits of previous stars to create new ones was possible. How long could some idealized society potentially last tucked but protected inside some mostly dead gas giant? Probably nothing remotely approaching a small fraction of a percentage of any round off errors in that number? Link to comment Share on other sites More sharing options...
