They say gravity is instentanious....?

Question

But when new matter is "created" *Yes it can be if I am correct, because when we create antimatter we would have to create matter.* Does it just instantly have gravity, or is it possible that the gravity takes TIME to reach out?

If so, what if it's possible that "gravity" is faster than light? So fast we could not measure it?

Answer 1

Trying to figure out how to work Kepler's Laws of Planetary motion into Einstein's Theory or Relativity huh? Modern physicists are rather recalcitrant when it comes to anything possibly acting faster than the speed of light. There are theories outside the mainstream that postulate that the strong nuclear force and gravity are one and the same. Look it up.

Answer 2

The correct answers are that gravity travels at the speed of light. One of the major failings of Newton's gravity law is that it fails to take the time delay from source (M) to attracted object (m) into account.

There are two prevailing theories on what gravity is: the relativity theory and the quantum theory. The relativity theory posits that gravity is the effect of bent space under the influence of some mass. That bent space lowers the potential energy close in to the mass; so an object at higher potential energy (i.e., farther away from the mass) will fall towards the mass. Such is the nature of energy, it always seeks the lowest potential energy.

Unfortunately the relativity theory of gravity fails to indicate why space bends near a mass. On the other hand, bent space around massive galaxies has been observed, validating the relativity theory. These bends are called gravity lenses because the bent space actually acts like a lens when light passes through them.

If a mass were created or destroyed, space would act accordingly. That is it would readjust itself to bend or unbend. And that readjustment would appear as a wave of space traveling at light speed.

It would be something like a bowling ball dropped on a trampoline. If we watched that with a high-speed camera, we would see the trampoline first bend at the point of impact. Then we'd see a ripple as more and more of the trampoline bent farther and farther out from the ball. For space, according to relativity, that ripple travels at light speed.

Quantum gravity posits a messenger particle called the graviton. And like photons that travel as waves, gravitons are predicted to travel in waves as well...gravity waves. These gravity waves, like light waves, are predicted to travel at light speed. The major attraction of this theory is that gravitons would be consistent with the messenger particles of the other three fundamental forces of the universe.

There are four fundamental forces that can describe all other forces. These four are gravity, electro-magnetic, and the strong and weak atomic forces. The non-gravity forces have observed messenger particles that carry the force message. Photons are the most well-known and understood messenger particles. They carry the electro-magnetic force messages. So we ask the question...if three of the four forces have messenger particles, why not the fourth....why not gravity?[See source.]

Answer 3

gravity is not instentanious. If the sun were to suddenly disapear, and not exisist anymore, the plannets wouldn't just instantly fly out of orbit, it would take 9 minutes before earth would no longer feel the effects of the sun's gravity on it's orbit. and several minutes after that before mars went flying out of orbit.

Answer 4

New matter can't be created, and the effect of gravity is limited to the speed of light.

Answer 5

No. They do not say garvity is instantaneous. In fact, it has been known not to be for almost 100 years, and this is one of the tenets of general relativity.

Gravity travels at the speed of light.
