I'm running a play by post RP set in an original world. The basic premise involves people around the world randomly developing super powers during puberty. You only get one power, plus the required secondary super powers needed for the power to work (usually), but only when applied to your primary power. You might have super strength, and this would endow you with the invulnerability needed to punch through steel, but you couldn't stop a bullet just because you have invulnerability as a required secondary super power.
No one has been able to figure out just how these super powers work. This is because any scientific experimentation to isolate an underlying operation inherent in all powers always produces massively contradictory results. It would be a slight hyperbole to say that every individual has a unique result on all experiments devised, but only slight. Super powers are a complete enigma.
Anyway, that's not really relevant to either the RP or this question. I wanted to create some super power ideas that were somewhat original (I want to avoid resorting to super strength constantly, and especially don't want the main cast my players will interact with almost constantly to have powers like that).
One of these powers is the ability to create a vacuum of quality equivalent to space anywhere you can see (but the only matter affected is gas). The idea is that the air is shunted into another plane of reality outside this one almost instantly, only to be pumped back into the area at a later date (determined by how long the user desires it to remain this way, but willpower is necessary to maintain).
Now I was wondering if this would have the effect I imagine it would. Assuming this is used outside, the idea is that the air outside the created vacuum will rush in, creating a powerful current of air pulling things towards the center of the vacuum (for simplicity of this model we will assume a spherical vacuum is created, though I haven't decided if that should be an actual limitation yet). The exact strength of this suction would, of course, depend on the volume of this sphere.
After this occurs the air originally in the area is shunted back into normal space rapidly, almost instantly. My theory is that this should create a pressure wave similar to an explosive, but without any fire, as the air that moved into the vacuum is pushed violently away.
This character is meant to be an extremely powerful fighter, so her normal strategy would probably be to create a vacuum at least a half a mile in size. So this should probably be used as the reference when calculating how powerful any effects are.
Now I am not a physicist, I never even took high school physics (physics was more of an elective, in my school at least, and I preferred computer based electives). So my question is do vacuums even come close to working this way? It isn't a very hard science fiction setting, so I think I could get away with just pretending it does, but if I didn't care I obviously wouldn't be asking.
And now that I think of it, are there any equations I could run to calculate the force generated by displaced air, so that I can figure out how powerful the suction and "explosion" are?
Oh, and other than its affect on visible objects (like if it pulled things into the vacuum, or the destruction of the explosive) this is pretty much invisible right? Probably a stupid question.
