It really was Earth all along...
- caseyy 3y agoI can just imagine Elorp Munk building a space company on Mars a billion years ago to colonize the frozen and inhospitable Earth. Bringing over some germs and then failing to establish a colony… that could make for some great sci-fi.
- dan_mctree 3y agoI wonder if there'd be any good way to confirm or rule out an ancient Martian civilization. Would Martian surface structures be able to last a few billion years? Or would Martian processes be able to make all of them disappear? And how about underground structures?
- ethbr1 3y agoI read somewhere that for geologic-scale signatures you need something that is: - Chemically inert - Recognizably artificial w/o context - Physically hardy - Planet-scale mass-produced On Earth, apparently "panes of glass" are one of the few things that qualifies.
