I remember reading some time ago that after the Sun runs out there's only enough energy in a state fit for fusion for like one or two more generations of stars in the universe, and after that the universe will go dark forever.
- dysfunction 5y agoThat may be true, but it's worth noting that the length of a "generation" of stars varies wildly depending on the type of star. Stars like our Sun might only live 10 billion years or so, but red dwarfs live 100 billion years or more so we could presumably live around them long after all the Sun-like stars have burned out.
- matthewdgreen 5y agoCan't we dump matter into black holes to draw things out for a while even after that?
- deadbeeves 5y agoFrom where are you getting the energy to do that?
- matthewdgreen 5y agoIf you have a bunch of matter (dead stars, planets, interstellar dust) is there some fundamental reason this can't be dumped into accretion disks, etc. in an energy-positive way?
