I have a question I long pondered and couldn't find any explanation to exactly what I want.
We all know that atmospheric pressure is due tu gravity acting upon everything on earth. this pressure act from all directions on all our body molecules.
However in space there is no gravity, no air, no such pressure, right? well, how can any shuttle, let alone astronauts get in ONE piece in space in the first place! shouldn't they explode from the inside out? shouldn't their molecules go apart because of the lack of the pressure?
There was one experiment where a steel cube-put inside a partial vacuum box- melted or detached from itsself apart internally. which makes perfect sense since without pressure matter can't hold itself.
Im really puzzled
regards
