Well, the speed of the propogation of gravity waves in GR was equal to the speed of light in a vacuum.  That may be off the table now.

Such is indeed the theory, but it is really merely a working hypothesis, since first-order measurements of gravitic waves are currently untestable.  All that we are accustomed to thinking of as gravity are only second, third, etc. order effects when it interacts with matter or EM-spectrum energy in ways that we can measure.

[quote]If you're referring to the Doppler effect, thats a phenomenon of light and its frequency observed relative to the angle and speed of the observer. I'm not sure how that would play into determining if gravity had a speed and if so what it might be.[/quote]


Yes. With the amount of shift observed near a mass (black hole, galaxy, etc) from a background star, the gravity well can be calculated. Now, wether or not you could also infer the relative speed of gravity from that, I donno.

Now if gravity is considered instant, that could open a whole can of worm holes.

Gravity is interesting, how and at what speed does the earth move that keeps us attached to it.??
 
Why do we on the a spinning object not notice the spin of the earth, true we are born into a grativitalion field, we know things do drop into the ground,  but to us we in the middle notice no movement , we do not fly into the air, how is the weather brought into all this planet gravity.??

We know all about gravity holding the moon in place our outer planets staying in their place, so, this system is stable all due to spinning objects and their Mass.  Mass generates some kind of gravity,

Then one takes a bucket of water and places say, balls of doe on the sides and spins it in the air, no water is lost, but slow down the spin and the doe falls off before the water slouches out.   Ask Mr. Wizard he can tell us why. Then the fact that one is worrking against earths gravity and causing a secont gravity  brings more questions into mind.

Give me a break, only few humans can figure this out--or so they think---But the simple humans cannot expect to understand all this, the Math and theroys are above understanding.  Fun for us to think about all this on a sub leavel   but it would not surprise me if a 8 year old on a computer  finds the ansewers and turns science upside down.
