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

No, gravity would act upon the weight. The vacuum does not stop that.

There would be no energy loss since there is no friction. The speed increases until it reaches the centre, then decreases from there until it reaches 0, at that point it would be at the surface on the other side. It wouldn't come to a rest if it's in a vacuum.

No, nobody agrees.
You appear to think thatgravity doesnt work in a vacuum, but it actually does.

Space, where things "float", does indeed have gravity.
Vacuum doesnt have any affect whatsoever on gravity.
Gravity is not affected in any way by a vacuum.
Vaccum or not, it makes no difference to gravity.
Gravity works exactly the same, whether in a vacuum or not.
You can have a vacuum, but gravity doesnt care.
Gravity is not the least bit concerned about a vacuum.

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.

No you are incorrect, explain where the energy loss is.

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.

Yeah. You're correct.

If you assume there are no losses in the system it'll just keep moving.

How would the earths gravitational force effect a mass inside a vacuume that runs from N to S?
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?

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?

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?

Gravity is the fundamental force of attraction that all objects with mass have for each other.

There is no (known) way to shield an object from the effect of gravity.

Having the vacuum there eliminates air resistance from the discussion as a means through which there would be energy loss. You don't need air as a transmission medium for gravity.

Think about it. If your reasoning is correct then anything in a vacuum chamber would be zero g. That is plainly false.

Ok since you bring this up.

I have a question for you. In this image you have three masses made of the same materials within a vacuume space, but they are different in size. My question is. Which mass attracks which? Or do they stay in the same positions?

Correct answer is that it would accelerate towards the center of the earth then as it passes the center it would begin to decelerate before being pulled back to the center where it would remain at rest.

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.

So in theory we would have a true perpetually motion device that we could harness for free energy..

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'.

Yes the colser you get to the center the weaker the gravity.

But, in the tunnel there is a vacuume all the way through earth from N to S. In other words there is no gravity reduction towards center. >A vacuume have no gravity. So if there is no gravity from N to S how can it fall towards the center?

posted on Oct, 20 2012 @ 08:02 AM
The answer to your question is Yes it would fall to the south pole...First off the universe is a vacuum outside our immediate atmosphere...has no effect on gravity...our gravity is made by waves that of magnetism that go from the north to south pole...the center of the earth being the strongest and shortest path...these waves actually push everything on to the earths surface, not pull from the centerin...there is a place called the Corral Castle in Homestead, FL. where a man moved huge blocks and built a complete castle...he said he figured out how the Egyptians built the pyramids...I personnally dont think the Egyptians built them...anyway they say he change the positive and negatives of the matter in one direction causing a levitation...not sure..still studing this theory....but your instructor is 100 percent correct !!
