Interesting how many stars with planetary systems are in the intergalactic void. How screwed the civilization there would be. They might not be able to travel to another star before their star dies. They'd have to do with handful of planets and cinders of a star for billions of years until they approach some galaxy and be the weirdest new kid in the neighborhood with everyone else surpassing them by eons in everything except self sustainability.

- d_silin 2y agoProbably not... Surface temperature would drop to -200 deg and all the atmosphere would freeze. Radioactive decay only provides only a 0.05W/m^2 on Earth's surface vs solar irradiance of 1000W/m^2.
- sitkack 2y agoI mean to say "in" to be specific. It wouldn't have evolved there, but those planets are just really huge spaceships.
- scotty79 2y agoThe question is how quick would Earth core cool down if the star died Nuclear is probably a better candidate for long term energy source
