What would it be like to live 100 milion years? Life in the Deep Subsurface Biosphere - Highlights

“I want to draw the similarities with alien life, and we have these questions. They're the same questions that we would be asking if we could get a sample from Europa or if we could get a sample from Mars. I think the parallels are partly in how we study them. They're teaching us how to look for strange life, but then they're also teaching us about what’s possible with life, and they're so close to the edge of what is and isn't life that it really helps us to sort of — I don’t know. I don’t know where to draw that line personally, but they at least show us that that line is maybe closer to non-life than we would have thought, than I would have thought.” Karen G.
