The Speed of Gravity

The point is that the mass of the system is conserved. A star is always losing mass but the mass remains in the solar system - same goes for a supernova. The mass-energy of the solar system is a constant. IMHO.

So right, since the fastest that mass-energy can travel is the speed of light - gravitons that travel at the speed of light suffice. So, gravity does change as fast as mass-energy so in effect changes are instantanteous.

Doesn’t energy exert a gravitational force as well? It makes sense to me that it should. Mass and energy are equivalent - just different forms of the same thing. Energy is just mass in motion.

I just had a retarded idea. If gravity was a type of radiation or thing that had mass. Could you focus this radiation?

for example earth=E rock on earth=r moon=M gravitational device= gravational radiation=() Focused Gravity waves/radiation/gravitons/whever = -->–>---->

without device

E(®) ) ) ) ( ( ((((M)))) ) ) )

With device

E[(®)]---->------>-----(—(-(M)))) ) ) )

What would happen?

would
E rM

Also if it was something like radiation would it also be possible to repel or reflect it?

then you could add gravational reflective/repelent=~

then

((E~~r] M

I think you will find that, yes, energy does exert gravity;
and even gravity has gravity when it is as strong as that found in a black hole.

Let me restate somethings for my own benefit, if any of the following is wrong let me know.
Gravitational radiation is produced by mass in motion. The quanta of this radiation is the graviton. Gravitons are not to be confused with the mechanism that communicates gravitational force.
Now time for some random thoughts…Is it possible that gravitons radiated by a black hole are actually produced an infentesimal distance outside fo the event horizon. The reason I ask is because it makes sense that a black hole must be able to radiate gravitons. Consider an electron moving through space, since it is a mass in motion it must radiate. However an electron has mass, obviously, so it must have a schrarzchild radius, since the electrron is a point particle it’s radius is less than the finitely small schwarzchild radius, which happens to be 10^-51 meters. So an electron has an even horizon, although a very small one. The only explanation for why an electron could radiate gravitons, or indeed even radiate photons is if the particle is produced an infintesimal distance away from the event horizon.
These statements are ofcourse on dangerous ground, they mix concept of general relativity with quantum mechanics which is always dangerous. However that doesn’t automatically make it incorrect and, as far as I know there is nothing that shows this “model” must be incorrect.

With that said it should bother you than a black hole can radiate gravitons, aside from the fact photons can not escape a black hole. According to general relativity, gravity has a time dilation effect. Infact, inside of the even horizon time no longer exists as we experience it, time ceases to pass. So even if gravitons travelled faster than the speed of light they would need to travel with an infinite velocity to escape.

One other comment, assuming gravitons exist, then antigravitons also exist. Moreover, like the photon which is it’s own antiparticle, an antigraviton would be indistinguishable from a graviton.

Please note none of this is meant to be taken as scientific fact, but I think it would be quite challenging to show it false, on the other hand I know I can’t prove it’s true.
