Going to do some quick research gimme a sec As I said, don't know much about the topic, just interested and curious. There may be other factors as to why we don't have said machines for water but do for space, didn't even cross my mind LOL

"Water pressure at the deepest point in the ocean is more than 8 tons per square inch, the equivalent of one person trying to hold 50 jumbo jets."

"Pressure can result from molecules of air (or water) hitting you - there is no pressure in outer space where there are no molecules."

"You would read a pressure of about 1atm = 760 mm Hg of air pressure within the space craft. The pressure outside the space craft would still be essentially zero because the escaping air would quickly expand into an ever increasing volume. "

Just some stuff I dug up, not sure if it's anything to base a comparison off of though.

light info page for deep ocean dives.

Got to be the brain...How can you fully comprehend the very thing that allows you to comprehend..?

it's interesting that it's thinking about itself

oceans for sure

I like turtles.

It really is quite facinating the more you think about it. There are probably thousands of spieces of animal that are undiscovered. Who knows, even dinosaurs
