Please explain how and why you think a vacumn stops gravity.
Also explain how satellites work if there is no gravity

A isolated vacuume tunnel that runs fron N to S. Have a even vacuume atmosphere from N to S. That means the vacuume dosent change even if it runs through earth senter. Only a change in the vacuume atmosphere from the N to the senter of earth would make the 10kg mass accelerate/travel. Wouldnt you agree?

What exactly are you saying here? It is a Vacuum Tunnel...thus no air friction. It would fall and achieve a certain speed which would allow it to fall past the center of the Gravity well for some time and distance...until it finally would reverse it's course and fall back.
This would go on for a while as it would keep falling to a shorter and shorter distance from Dead Center where it would eventually come to a rest. Split Infinity

This is not correct. Gravity is the effect making the object fall. The Center of Gravitic Effect is the Earths Center. The object would begin to be effected in the opposite direction the moment it passed through the center of the Gravity Well. It would slow till it stopped as it would now be in effect be like an object that has been thrown skyward. It would use up it's Kinetic Energy from the initial fall and fall the opposite direction. It would pass a few times through the Earths Center before coming to a rest dead center.

forcre = mass x acceleration of gravity
g = 0 in centre..
the object would slow down as g decreases until in centre object becomes stationary because g = 0

No, its been accelerating all the way down to the center. It would stop accelerating at the center but would already be moving fast by the time it got there. The acceleration would be applied against it as it came out the other side.
It would end up in the center but not in the first pass.

It would never end up in the centre, it's simple harmonic motion, there is no friction.

Yes it would.
The answer is wrong. If i tell you that there is vacuume inside the tunnel all the way from the North pole to the South pole. How could mass travel to the South Pole? Or even to the core?
If the 10kg mass travels. That would mean the tunnel is not a vacuume from N to S. Correct?edit on 27.06.08 by spy66 because: (no reason given)

The vacuume or the 10kg mass will never see the force/mass working on the out side walls of this tunnel.
If it does. What kind of physical force would act as the gravitational force that makes the 10kg mass fall?

Totally ignorant guy here, so forgive if this is stupid: Isn't the universe in a vacuum? If so, according to your premise, none of the planets or galaxies would be able to move. Right?

My opinion is that it would accelerate as it falls, passing through the center of the earth and reaching the south pole 42 minutes later. On its way up to the south pole it would be decelerating and reach zero speed at the surface.
Then, like a pendulum, it would return to you at the north pole another 42 minutes later.... then back to the south pole, and so on forever.
Of course this assumes perfect vacuum, no touching the sides of the tunnel, and so forth.

the closer you get to the center of the earth the weaker the gravity. also the 'tunnel' would have to curve to allow for the earths rotation, ensuring the weight doesnt touch the sides of said 'tunnel'.
