Submarines in space?
Unable to sleep I wondered what would happen if you put a submarine in space? Would you be able to survive in it?
To be honest I think yes maybe it could work. After all it is pressurised with its own air supply. Although I don’t think it would be able to move at all. Another consideration is the radiation in space. However these days most submarines are nuclear-power anyway.
Similarly could you take a space station and put it under the water? Would people be able to survive in it?
