Although gravity is clearly related to the mass or matter of a body, what is the mechanism which causes bodies to attract?

It's all about how much you have had to eat, and whether you need to sleep some off before its safe to jump off the table.

Not according to your arithmetic, which shows zero net force for any value of r.

I wonder if to calculate the forces is even possible. Seems too complicated to me. What kind of math tool able to solve it?Each charge in mass 1 acts with every charge in mass 2 at various distance, we have as many as 4 x E x M forces to deal with. But all in all, if the calculation can be done and proof that the net electrostatic force between two bodies always end up attraction and follows f=m1m2/r^2=kq1q2/r^2, the mystery of gravity will be cleared.I wish Newton is still alive!

The purpose of Einstein’s new theory has often been misunderstood, and it has been criticized as an attempt to explain gravitation. The theory does not offer any explanation of gravitation; that lies outside its scope, and it does not even hint at a possible mechanism. It is true that we have introduced a definite hypothesis as to the relation between gravitation and a distortion of space; but if that explains anything, it explains not gravitation, but space, i.e. the scaffolding constructed for our measures.

There seem to be two ways of looking at gravity. G R says it is not a force, it is a distortion of spacetime.

Mass splits up grains of an ether and throws away them. Shared grains slip through other mass and do not touch it. The return stream of large grains of an ether touches mass and pushes it to the big mass. Shared grain of an ether gradually incorporates in the whole. [:I]

My thought, gravity is simple thing,,matter-density.

The warp of space-time is a mathematical description of the effect of gravity, …

Space-time is curved because gravity bends the path of light in Euclidean space, and Minkowski redefined "straight line" as the path of light.

I believe gravity, ….

and all the other forces of nature, result from exchange of momentum between regular energy and dark energy.

Then there is Mark McCutcheon!!! He believes there is no gravity. He believes that all the matter in the Universe is expanding. If we drop something, what we perceive is not that object falling to the ground, it is the ground coming up to meet the object.

You forgot to give me a bullet. [xx(]

Massless bullet?

I meant you debunked many posts in this thread. Why not mine?

I suggested a mechanism to explain gravitation. What's your thought about it? Thanks

Your problem is one of, not gravity. There are certainly classical arrangements of charges where there are an equal number of positive and negative charges in each body making each body having a total charge of zero but for which the net force is not zero. A simple example is two electric dipoles. The net force between them is not zero. However when the force is proportional to charge and not mass and therefore the rate at which they accelerate towards each other will depend on the mass of the accelerating body. However gravitational acceleration is independent of a body’s mass so therefore this can’t be viewed as gravity.

Thanks for the reply.

I am confused. Isn't mass proportional to its total charges?

If 1 kg of gold carries 10^27 electrons, 2 kg of gold should carry 2 x 10^27 electrons.

Put those two gold balls R from Earth, the net electrostatic force between Earth and two balls is proportional to their charges, therefore 1:2.

The mass ratio is 1:2, F=Ma=Mg, therefore gravitational acceleration is independent of a body’s mass.

Pete, thank you very much taking the time teaching me.

I am still confusing.We knew atoms are each electrically neutral, but they attract to each other in short distance to form matter. The same force in long distance should be still there, acting as gravity.F=M1M1/R^2, M1=m1+ + m1-, M2=m2+ + m2-. F=cQ1Q2/R^2Can you see the connection? Mass is proportional to total charges in a body.

Light bend by gravity is because the medium of light is denser near sun/matter/body, the medium they called ether, I call it enertron, a tiny tiny negative charged particle that fills the space.

If light was particle, why light beam expending with distance?

Why is light change speed in different matters?

If most space within matter is vacuum then light particles should pass through with same speed.

If we shoot electrons at matter, what stops electrons hit straight on nucleus?

They attract each other with strong force, plus electron has momentum towards nucleus?

If nothing stops electrons hit nucleus, nucleus reaction should be everywhere and we won't be here.
