Humanity could survive on geothermal if Earth was known to face ejection from the solar system. There could be civilizations on those planets.

- 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.
