Gravitational Pull

If the sun and the moon revolve around the earth

the the earth must have a substantial amount of mass to acuire this pull( even if the earth is excelerating up at 1G)

People have said that the other side of the earth was made of just simple rocks, but i belive that would not have the mass required to have the pull of the sun and the moon around the earth.

This has led me to believe that the other side should be made of a material with more mass, like lead or any other metal.

This has also led me to believe that the otherside might be radioactive!  If there was a nuclear reaction going on the underside of the earth this could produce heat that would match what others believe as the center of the earth and the molten rock that lies there.

This would also help the increase the weight on the other side so that the pull could occure for the sun and moon to revolve around the earth.

Please let me know what you think!!!

I once theorised that the underside of the earth was fusioning, which was producing the UA. This also conveniently explains the molten mantle that we find underneath the earth.

Gravity doesn't exist. Read before you post.

You're going to be so pissed off when gravitons are discovered. Actually you'll probably just say it's a trick

And how would these prove gravity?

Gravitons would do nothing for gravity. They would do something for gravitation though.

How would gravitons prove GR to be incorrect?

What curves space?

In terms of GR.  How does space know how and by how much to distort based on its distance from an object with mass/energy/momentum?

So you would agree that there must be some sort of information transfer between objects with the 'big three' and space?  We can't detect this information transfer that we know must be going on.  Why can't the 'graviton' be this information carrier?

Well, if gravitons were discovered, general relativity would be disproven and gravity would be unified with the other fundamental forces.

Actually, if graviton is discovered, General Relativity and Quantum Mechanics will be unified into a theory called "Quantum Gravity". It has nothing to disprove GR, since both theories reached the same result.

How did you come to that conclusion? Why do you feel the discovery of the graviton will somehow unify QM and GR?

If the graviton turns out not to exist, it will render all work based on quantized macroscopic physics flawed, and destroy virtually all the accepted notions of a unified theory of physics since the 1970s, including string theory, superstring theory, M-theory, loop quantum gravity, and quantum gravity, among others.

Quantum gravity is the field of theoretical physics attempting to unify quantum mechanics, which describes three of the fundamental forces of nature, with general relativity, the theory of the fourth fundamental force: gravity.

Again I ask you, why does the discovery of the graviton necessarily mean that Quantum Field theory will be compatible with GR

In particular, contrary to the popular but erroneous claim that quantum mechanics and general relativity are fundamentally incompatible, one can in fact demonstrate that the structure of general relativity essentially follows inevitably from the quantum mechanics of interacting theoretical spin-2 massless particles (called gravitons).

as I understand no one has accomplished this task.

and like you quoted, these theories all rely on the graviton existing as defined per QF theory.

But there is no aspect in current QF theory that can be unified with GR.

So while the graviton may be discovered or observed, Quantum Gravity will not necessarily be validated.

the existance of the graviton does not necessarily validate any of those theories.

Wow, you are so sure about the future.

It is in fact you that seems very sure of the future here.

I find it interesting that part of the wikipedia was unsourced.

General relativity can be derived as consistent local field theory of massless spin 2 particle in the low-energy limit.
