A vacuum does not cancel out gravity, it only takes other matter and the atmosphere out of the equation, producing zero drag. Gravity would be the only force acting on it, but it would still act on it.
lets say we construct a perfect, absolute contained vacuum in interstellar space,, and the only thing that is in the vacuum is a 10kg mass........ the mass is magnetic,,.,, and outside of the vacuum we have magnets,.,.,. would the magnets have an effect on the mass? if so,, would their effects cause our perfect, absolute vacuum to no longer be a perfect vacuum ( barring the 10kg mass in the vacuum in the first place)?
p.s. i know this is different then gravity...
Again, you are not understanding what a vacuum is...
in a vacuum,, with no energy,, no matter,, no particles,, in a pure vacuum with nothing but nothing,,,, what gravity is effecting ,, one single object,, in the vacuum?

The gravity of the entire mass of the Earth surrounding the tube.
ETA: I see the Chiten already got that one too but still that apparently can't be mentioned enough.
Why is there this thought that a vacuum insulates from gravity?
edit on 4-11-2012 by DenyObfuscation because: (no reason given)
i think my problem with understanding is that,,, a vacuum means nothing,,, no contents
Vacuum is space that is empty of matter.
en.wikipedia.org...
how can the force of gravity effect something within a volume with no forces present?

No matter.

The mass of the Earth and the mass in the tube are attracted to each other by what we call gravity. The vacuum is a non-issue with respect to gravity as gravity is not matter. Light travels through a vacuum and magnets of sufficient strength will attract each other when separated by a vacuum. Magnetism is a force as is gravity.

Equilibrium is the state of most things in the uninverse. All of the forces balance out except for the forces causing motion or change.

There is a big difference between a vacuum in a chamber and the vacuum of space.
The vacuum of space is always neutral. A vacuum in a chamber is always negative no matter how pure it is.
A particle surrounded by neutral vacuum of space will always act differently than a particle in a negative vacuum chamber.

That is because you don't know what a vacuum is. You don't even know the difference between a absolute neutral space compare to a absolute vacuum.
And i probably have to go on for a very long time. Because you people take so long to understand.

Yes, I agree.
Should have maybe added that to my post in the first place.

What??
Is one a Hoover and the other a Dyson or something?
