a stupid question.

[bluescouse]

The classic scifi scenario, a spaceship has a hull breach, everything in the room gets sucked out, because of the vacuum of space. Most fictional space ships have artificial gravity, (probably because it is easier to film that way).
My question is, if there was such a thing as artifical gravity, wouldn't it hold the air and everything else in the ship despite the breach?

[freethinker]

In a jetliner, when there is a breach in flight, do things stay where they are? The gravity is real as opposed to artificial, but think about it.

My question is, if there was such a thing as artifical gravity, wouldn't it hold the air and everything else in the ship despite the breach?Usually it is because of a pressure differential that things go flying out, higher pressure inside the spacecraft or jetliner then outside of it. (A jetliner also has a venturi effect going on because of relative speeds)

But it is a very good question that would require a better or greater understanding of just how the gravitational field would be construed/made as that would decide if even a 'hull' was required in the first place.

Keep thinking as obviously in your case it is getting you somewhere, as demonstrated by the very good question.

My question is, if there was such a thing as artifical gravity, wouldn't it hold the air and everything else in the ship despite the breach?Artificial gravity is an unknown hypothetical with unspecified properties. Actual gravitational attraction, though little understood, appears to be a different force phenomenon than that which occurs with the juxtaposition of various pressures of gases.

Artificial gravity may be like Temperature. In other words, there may be a limit at zero, where

{delta} t -> 0

similarly

{delta} g -> 0

Consider the concept g exists when -g <= 0 ...

actually the most dangerous problem is the difference in pressure.

{delta} p = 5lb^3/sq in (sea level if i remember right)

{delta} p1 = 0.00003lb^3/sq in (pressure in space)

now the change with respect to time.

f(x) = P(x -> x1) ; f(x1) = P(x1 - > x)

you are looking at a magnitude force of about 500,000. this is why things can implode.

I have yet to figure out why sci-fi space movies for the most part depict sound in space....

Artificial gravity may be like Temperature. In other words, there may be a limit at zero...Yes; and, as with temperature at zero, there is no existence. Thus, "an unknown hypothetical with unspecified properties."

bluescouse your question is well supported by (the evidence) this planet, as we ride on the outside shell of this 'space-ship' planet earth, with NO ill effects as a result of our exposure to outer space...so your premise might be VERY viable, no one really knows "The" Conlusive answer ...just yet, but it is Good thinking on your part...not really the 'Stupid question' pose you used to cover the what? fear of asking it?

Usually/sometimes the questions that appear as the most 'stupid' are really the best place to start good explanations and find better answers, after all, in most cases, questions are (waaaay) more harmless then ignorant statments.

Glad you asked it! :cool:

bluescouse your quetion is well supported by (the evidence) this planet, as we ride on the outside shell of this 'space-ship' planet earth, with NO ill effects as a result of our exposure to outer space...Have you considered that our atmosphere, that we carry with us, and our "actual" gravitational field that is always present, protects us from the scenario's "hull breach"?

Glad you asked it! :cool:BTW that is Because of 'Gravity' that it works that way, so the evidence for it is ON your side, no question.
