That's because it's a much harder question than most people would think, or maybe even agree on. Good you axed.

A physicist would probably say that force is force, and it's contents are blown out. Then again, if I used a suction tube with the same vacuum attached and stuck it in you, you'd probably not say so, even if the whole situation is not really different. The 'suction' tube does nothing without you delivering the pressure, right?

In the same sense, 'force' is only something you can identify meaningfully in a very strict and local sense. One Newton pushing a block of wood over my table is totally meaningless inside the Sun, for instance. From the viewpoint of the 'vacuum' there is just a infinitesimally small statistical readjustment in pressure difference, hardly worth mentioning (your attempts at screams in protest notwithstanding).

That's why when you are on Newtonian level 'force' is everything, while in quantum mechanics it all essentially boils down to taking the 'vacuum' viewpoint, that of statistical redistributions. Philosophically you find that terms like 'force' and 'blown out' or 'sucked out' are only meaningful in a very defined context.

Like that of your life ending withing a few seconds and you not caring one whit about all this crap. Not only is everything relative, according to Albert, It all depends on context.

this is a clip of a water balloon being popped in a 0g environment on one of those parabolic flights. while not in space as sich it gives a good idea of what yould happen in a space sraft such as the ISS and hopefully answers the surface tension part of the question. and it looks cool too...

Homer simpson went into space,he was eating crisps( chips they call em that side of the water) when his head went through the ant experiment,if NASA sent me into space,they would probably get the same result,ive just got more hair than him.

every village has one !
