What geos AGIANST the laws against gravity?

Answer 1

Idunno, a chicken with a zeppelin.

If your question is serious (and not a joke), the answer is nothing that we know of. The laws of gravity (invented by Newton, refined by Einstein) are absolutely universal as far as we can tell.

Answer 2

Your question seems to ask if gravity can be canceled or shielded. Therefore...

According to the currently accepted best theory of gravitation, Albert Einstein's General Theory of Relativity, there is no gravitational shielding. Gravitational shielding is also absent from Isaac Newton's classical theory of gravity. Astronomers performing solar system calculations would use one of these two theories and would therefore not include gravitational shielding.

The concept of gravitational shielding was introduced by Italian physicist Quirino Majorana in the publication, Journal de Physique et le Radium. The citation is Q. Majorana, J. Phys. Radium 1, 314 (1930).

In order to continue to be accepted, the General Theory of Relativity must repeatedly survive experimental challenges. Scientists look for anomalies, differences between theoretical predictions and actual experimental results, during eclipses.

A recent (2001) paper by C.S. Unnikrishnan et al. PhysRevD.63.062002 is titled "Anomalous Gravity Data During the 1997 Total Solar Eclipse Do Not Support the Hypothesis of Gravitational Shielding".

So far, it appears that no evidence for gravitational shielding exists. Thus, if you stand on the opposite side of the earth to the moon you will indeed experience the pull of gravity from both the earth and the moon.

Answer 3

Not if you fly a foot-launched aircraft such as a hang glider. Oh, wait, they only work with gravity, never mind. Not to worry, defying gravity is only a misdemeanor. You jump off a cliff, chances are pretty good you'll miss the meaner pointy rocks at the bottom before you make your big splash.

Answer 4

Richard Feynman, one of the greatest and certainly the most charasmatic physicist, said that the best anti-gravity machine was a chair!

After all it stops you from falling to the ground!

On a serious note though, negative energy (and hence negative matter) . Such matter would be repelled rather than attracted by gravity. It is used in ther theory that deals with wormholes. The closest known thing to negative matter/energy results from the Casimir effect.

There is no evidence for negative energy or mass... that doesn't mean that it doesn't exist though.

Answer 5

nothing, everything in the universe has mass and if an item has mass it experiences gravity. However there are other forces which counter gravity.

If the force acts in the opposite direction of gravitational pull and is stronger then gravity the object will move is a direction opposite gravity but the force due to gravity is still present.

Answer 6

the only thing that would defy the law of gravity is probably something like antimatter.. although I don't know if antimatter would even be immune to gravity because gravity is caused by a curve in space and not by the attraction of particles..

some things (like helium) can appear to defy gravity, but it's just because they are less dense than the air we breathe.. if you put a helium balloon in a vaccuum, it would fall like a rock..

Answer 7

The old professor says: Nothing that I know of. If something did, then the laws of gravity wouldn't be LAWS. Newton didn't invent the laws, he merely discovered them.

Answer 8

umm. nothing? im pretty sure gravity applies to everything. unless there is no gravity or some other force interfering with it, like in a vaccuum

Answer 9

Nothing defies gravity, but merely counters it or manipulates it. It never disappears, but physical matter prevents it from pulling you straight to the center of the Earth.

It can't be defied, but merely countered or manipulated.

Answer 10

There is nothing that can counter gravity.
