anti gravity?

Question

is there a way to counter gravity to enable a object to float free in the earths atmosphere

Answer 1

To have anti gravity, we must first have gravity defined as something akin to a quantum. All known matter quanta, like an electron, produce anti matter quanta when the matter is created in the lab (e.g., in colliders). Anti electrons, called positrons, are frequently created as by products in colliders.

So we presume the quanta--anti quanta symmetry holds for all particles. The reason anti matter does not proliferate the universe is because it is very short lived. It soon disintegrates into energy...usually photons.

Unfortunately, no one has ever observed a gravity quantum...called a graviton by most physicists. In fact, only a handful of theories (more properly hypotheses) can account for a particle with the characteristics of a graviton. String/m "theory" is one such WAG.

So there is no such thing as anti gravity, an anti graviton, simply because there is no such thing as a graviton...at least not yet. Perhaps it will be found in the future; then we can readdress your question.

However, we can and frequently do counter the force of gravity, which we can and have observed and measured for centuries. Newton's F = GmM/R^2 describes the force of gravity quite well. Understand, countering the force of gavity is not the same as anti gravity. Countering F simply means to reduce it somehow so that the net force, after the reduction, is less than F.

For example, gravity wants to pull you into that chair you are sitting in. But the chair is pushing back with a counter force equal to your weight, which is the force of gravity. In the net, the chair push exactly counters the gravity force. That is, f = W - C = 0; where W is your weight (the gravity force) and C is the chair pushing back. So, something as commonplace as a chair counters gravity. But that's clearly not anti gravity.

Balloons "float free in the earths atmosphere." For this, their bouyancy force exactly counters the force of gravity, which wants to pull that balloon to the ground. But that's clearly not anti gravity. Ditto airplanes and rockets...they float or fly through the air as well, but without anti gravity.

Bottom line, there is no anti gravity in the sense I think you mean it. But there are plenty of ways to counter it, like dropping an elevator down a shaft for example.

Hello, my name is Pavel Tashev part of the Gravlet team. The team is focused on anti-gravity research..may be it will be interesting for you.

Answer 3

It is possible to form an artificial field of gravity but it would still act in that omni-directional manner as it does within our planet. The equation for a field of gravity is c2 = E/m, which means it is possible for a mass to have an increase and decrease of this force. At http://youtube.com there is an experiment "successful gravity experiment" that demonstrates a field is able to be formed and collapsed. Another video is to be posted soon "gravity engine" that describes how this force is able to propel a spaceship.

So, were you to form an artificial field above yourself, there would be a reduction in the force between you and our planet, but above the artificial gravity the force would increase to an extent greater than on earth.

Answer 4

Let your object be a spherical ball. Now enclose the ball in a hollow sphere, and let it fall.
The enclosing hollow sphere will experience gravity, and will fall. Whereas the object within the hollow sphere experiences weightlessness, and will remain suspended in the hollow sphere, without touching any of the sids.
The same thing happens when the cables of a lift break off, and the lift starts falling (9.8 m/s). The passengers inside experience weightlessness, and are suspended in mid-air in the lift.

Answer 5

Artificial satellites do it all the time.
