Since the speed of Gravity is instantaneous can ........?

Question

gravity be used to transport information from point a to point b without time being a factor?

If you click on the link you will see that Gravity is instantaneous. It connects all matter everywhere instantaneouslly

I am not sure what type of information..

Jack....Light can be bent by gravity. The lense effect of light passing a large gravity field I believe shows that

Besides light and gravity are not the same.

Thanks for the link HM 10...
Interesting ideas. They seem to disagree with the link I provided

Rick B... Great answer. I believe you are right.

Thanks Dr R... Another great answer.

Answer 1

Theoretically you can oscillate a mass up and produce a gravity wave that will radiate out in all directions. by modulating the oscillation frequency or amplitude (like they do with radio), you can transmit information that way. This was the subject of a Larry Niven short story. However, the gravity wave (or any disturbance in gravity) only propogates at the speed of light.

Answer 2

Gravity is (in the Einsteinian view) treated as a geometrical effect (an effect of the curvature of spacetime) rather than as something that "goes" from one place to another. I gather from the abstract of the indicated article, that the author is proposing a view that is mathematically equivalent to the spacetime curvature interpretation, but which views gravity as "traveling" from A to B at an instantaneous (or nearly instantaneous) rate.

However, that does not mean that information can hitch a ride on it. In order to propagate information via gravity, you have to _distort_ the field in some way (e.g., jiggle a star really fast), and then wait for the distortion to propagate. That distortion, in both the Einsteinian view and the author's view, is still limited to the speed of light. To quote from the article's abstract:

"Such a change of perspective requires no change in the assumed character of gravitational radiation or its lightspeed propagation."

Answer 3

The speed of gravity was predicted by Einstein's general theory of relativity to be the speed of light. Indeed this has been measured by experiment and shows that it travels at the speed of light..
See ref to the experiment.
Your ref is an attempts to construct a self-consistent gravity theory in which gravitational interaction propagates at a speed other than the speed of light, but this is not a mainstream theory

Answer 4

The effect of gravity is not instantaneous, if the sun disappeared, the Earth would still retain it's orbital path for 8.5 minutes, this is the length of time it takes for the gravitational field of the sun to decay over 93.000.000 miles, the same as the speed of light.

Answer 5

Sorry, the speed of gravity isn't instintanious. If particle physics is to be believed, the gravitron (boson, or messenger particle for gravity) travels at the speed of light. For that reason, gravity is just as good as light (or electromagnetism) for communicating over long distances. And, as it happens, it's a heck of a lot easier to do so with the electromagnetism.

Answer 6

yes, but always the recieving party will have to be lower to the center of gravity, and the sender will have to be above it, also no means of transport is perfect, there will be a flaw.

Answer 7

No. Data transmission through hard wire is done by molecules bumping each other in a chain reaction. Fiber optic transmission is still measurable by the speed of light. Telekinesis still has to overcome the space/time continuum.

Answer 8

Good idea. You will need "something" that will actually put information on gravity wave. but that will increase the inertia of gravity wave. and slow it down. so it won't be instantaneous after that. :D

But good idea anyway.

Answer 9

It is not instantaneous therefore the rest of the speculation based on this is false also.

Answer 10

another Newton in the making. i have got a gravity-ache.
