      No, space is hard because of radiation and great distances, but a hole in the hull of the ship, for example due to a micro meteorite, can even be covered with a piece of duct tape. A hole in the hull of a submarine however is a catastrophe, if it does not directly cause the hull to implode, the water that enters has enough pressure to cut you in two.

        The current “space” we go into, tends to have a tinny amount of atmosphere. (1.322×10-11 Pa according to some random top result on Google)
        So if you want to keep inside conditions at around 1 atm for a human to stay, that’s all the difference you need to keep, and a duct tape might work.

        But the void I refer to, is very different.
        Think:

        • Vaporising metals
        • Theoretical quantum bubble formation

        Normal spacecrafts made for “space”, might even have their outer surface constantly being diffused in the void.

          Sure, but doesn’t the outer surface diffusing apply to the friction of water against a submarine’s hull too? No clue about theoretical quantum bubbles, but it doesn’t seem like anything that would affect spaceships in particular.

            friction of water against a submarine’s hull

            I can’t say for sure, but I feel like the affect due to said friction would be much lower, considering we are managing solid-solid friction in a lot of places.

            theoretical quantum bubbles

            Yeah, that’s not relevant. Just added that to clarify which “void” I’m talking about.


            The vaporising metals problem, I think might be alleviated by covalent bonding materials, so polymers? But not sure about that either.
