To survive beyond 1 Gy from now, life will need to move underground where the water is and hopefully much cooler than the eventual surface. Also, such life may/will become necessary to relocate to Mars, hopefully taking resources with them. (I don't say "us" because of likely dramatic evolution.)
- zmgsabst 2y ago1 Gy ago, life wasn’t multicellular. I don’t think we have the ability to meaningfully predict such scales.
- thombat 2y agoThe only reason that the subsurface rock is cooler than magma is being able to conduct heat through to a cooler surface. When that surface becomes exterminatingly hot and remains so for a while the subsurface will be heating up too. Since the sun is estimated to remain a red giant for about one Gy it will become hotter than the surface.
- Timwi 2y agoAt that scale of time, it's not implausible that we have the technology to relocate Earth itself by then (e.g. increase its orbit).
