We are gradually building and expanding the space station, and beginning the long process of manned inter-planetary travel to Mars. Is the concept of human existance underwater null and void?
we already survive very well underwater (just look at submarines and scuba diving) - at present
Living underwater is in some ways harder than living in space, they say we know more about the surface of the moon than we do about the bottom of the oceans which basically tells us how difficult an enviroment it is to survive in.

What is true is that visibility in space is better, which is why we know more about the surface of the Moon (but not the surface of Venus) than the bottom of the ocean.
The reason we have spent more hours under water as its a lot easier to get to the sea than space if we could find an easy way to transport us into space and to travel through it then that situation would change.
Also visibility in water isn't really a problem deep down as the water tends to be crystal clear all you need to do is bring some lights with you and its amazing how far they can see.
The problem with water is the pressure which is can be far harder to survive in, a vacuum is childs play compared to the presure of water deep down.
I wonder what the chances are of folding a semipermeable membrane having a large area, into a little canister by folding, and using it to filter oxygen out of the water for breathing purposes.
