| Jul 24, 2020 at 12:36 | comment | added | user6760 | So what's preventing water from boiling? | |
| Jul 24, 2020 at 12:34 | comment | added | Speedphoenix | @DWKraus The moon is very large, at least more than the earth, but with little atmosphere, and the geysers are strong enough to reach L4/L5. I have not read The Integral Trees. I am actually not sure about the energy input, I am looking for how life in liquid water would evolve. The part on radioactive material was mostly to give an explanation on the liquid water, but is outside the scope of the question | |

| Jul 24, 2020 at 11:57 | comment | added | DWKraus | I'm not sure, but I suspect the water would ablate off the surface until it had dissipated into space if it was warm enough to stay liquid. It would be in constant flux at best, which isn't great for evolution. You'd at least need a containment for the surface. Anyone know this better? How does new material (especially heavy radioactive material) add here? Enceladus is cold and slow, as is Saturn's rings. Also, that's a lot of radiation - how big is this thing? I have a feeling exchance w the moon is critical here, but can't quite see the pieces. Is there life on the moon? | |
