Hi, I'm wondering how much longer life on earth as we know it should be possible.
If I understand correctly, the sun will eventually become a red giant so large that it would engulf the earth inside it. Obviously life on earth would be impossible by that point. But it will probably become impossible earlier than that, what with the oceans boiling away, and just being too damn hot. How many years from now would that be? Would it still be possible to live underground? Is there any other place in the solar system that might be habitable if it comes to that?
