sorry but school project is why I ask so much, so are you saying that the vacuum in space is diffrent than if we removed the air from a container to negative pressure and measured it in psi? or is it only a vacuum of molecules and we just don't know how to explain the absence of them?
I commented my hypothesis with a thank you to tumbling dice but I don't see it in thread so Ill repeat it; I don't believe that outer space is a vacuum but rather that Earth has a bubble of pressure. is there any proof either way?
lets say at 1000 miles away from Earth how many psi of a vacuum are we talking? and is the vacuum differ in different parts of outerspace to let's say 1000 miles away from Mars to keep it apples to apples
I just read that outer space was mostly hydrogen at 75% but I did not know how much of a vacuum it was to make it unusable. how many ppm is it? or am I just misinformed
