Without a protective suit, what would be the fate of a human body in vacuum? Would it freeze? Disintegrate over time? Would it stay “preserved” forever? Could microbes hosted within the body continue to live off it until there was nothing left? If there were no large bodies around to exert gravitational force, would it continue to remain in the state of its initial perpetual state of motion?
Scientists have a pretty good idea about what will happen to it.
It will eventually cool down and freeze, but not for quite a while (space is a good insulator, and it takes a while to divest yourself of heat in a vacuum). Molecules, however, will still vibrate and collide, giving the outermost ones sufficient energy to escape. Eventually, over a VERY long period of time, it would evaporate.
