what is gravity ?

Answer 1

Gravity is mutual attraction between two elementary particles, each of which has the property of splitting larger p-waves (in the ether foam medium) into two smaller p-waves. To conserve both energy and momentum in a wave splitting event, it is necessary to impart momentum to the particle in the direction of relative motion between the particle and the p-waves. The smaller p-waves have no effect on the next such particle encountered, so each particle appears darker than the background in the kind of p-waves that get split. Therefore, the larger p-waves push the two particles toward one another.

That is one small part of my Fractal Foam Model of Universes.

P.S.: Thanx, goring. I was inspired by the flawed Fatio/LeSage model, which I believe I have improved upon greatly. Never heard of Carezani or Autodynamics. I'll be boning up on it tonight.

P.P.S.: After a few minutes of browsing, I don't see any indication that Carazani has cured the most obvious defect of Fatio/LeSage. How can a particle absorb enough "pico-gravitons" to account for gravity without doubling the particle's mass every picosecond.

VanFlandern and Slabinski think that the energy of the one absorbed "classical graviton" is somehow transferred to the 100 quintillion scattered "classical gravitons".

My own model does it by splitting a p-wave; the smaller p-waves take away virtually all of the energy; momentum is left behind because of the angle of divergence between the two smaller p-waves.

Answer 2

According to Dr.Carezani relativity theory Gravitational power is caused by not the Graviton of quantum theory which only applies to micromasses;but the picograviton which applies both to micro and macromasses.The Carezani pico- graviton has a small mass as opposed to the Graviton which is defined as masseless.Hence Gravity is caused by Picograviton absorpsion and emission as per The theory of Autodynamics.Acceleration is directly proportional to to the number of Pico- graviton received per second per Unit area on Earth.The calculation of acceleration agrees with value found by experiment. The relativity theory of Ricardo Carezani's Autodynamics is one of the few theories which outlines a Gravity mechanism .
There are many other theories but are only understood in the light of General relativity.
Newton and Fatio had similar idea concerning the mechanism of Gravity.

In Reality the mechanism of magnetism and electricity are basically one and the same Gravitational phenomena. Einstein tried to find a correlation where he could Unify Gravity as the curvature of space time with One basic formula where he could Unite Atomic forces existing in the atoms ,Electrical forces and magnetic forces into one common cause.This is called Unification of forces theory.

Another theory of gravitation which has just surfaced is the quantum aether dynamics of Thomson & Bourassa. Which are proving that a force that Unifies all the other forces in nature exist.One of the analysis was based on the Casimir Effect Experiment.

There are many Gravity theories which one would be the prevalent one depends on workable experiments.

Answer 3

gravity is a force just like electromagnetic force, Strong Nuclear Force, and Weak Nuclear Force.

Electromagnetic force is strong enough to hold you from falling to the center of the earth due to the EM forces in all the molecules just under you.

Gravity is much weaker than that. In fact; when i sit in this chair and raise one foot, I am overcoming all the gravity of this entire earth!

Gravity of the earth warps space time.

If you are in space, you can feel the earth warping space time as soon as the G's come back heavy during descent.

if you are in space , you truly are out of this world.

Some postulate that gravity floats between our universe and another adjacent universe
as freely as passing through a membrane.

There is a THEORY OF EVERYTHING that tries to establish that the tiniest building blocks of matter are also the building blocks of Force, like gravity , electricity, etc.

They postulate that string theory explains this by linking matter , energy, and force together as being made up of the same stuff.

Answer 4

It's a localized curvature of the space-time continuum brought about by the presence of mass and mediating a force between masses through a massless intermediary vector boson called a 'graviton' which generates the guage field called 'gravity'.

Answer 5

The mutual attraction between two or more objects which possess a mass within a field of effect.

The size of this field is related by the formula g = GM/r^2

The force generated by this field on the objects is related by the formula F = GMm/r^2.

Answer 6

gravity is one of the four fundemental forces of nature that is always attractive, never repulsive, it is thought that the graviton is what provides the concept of gravity which has no mass, but it is no where near proven yet

Answer 7

Gravity is what keeps everything from floating away!

Answer 8

gravity is the bending of space around mass.

Answer 9

This is pretty basic science stuff, its a little late in the school year to be asking a simple question like this.
And wikipedia or any other encyclopedia site would answer it best (and you should do your own reading, its the only way to learn).
