Report Observational evidences for the speed of the gravity based on the Earth tide

[tom_mai78101]

We have found that the current practical Newtonian formula for the gravity tide of the Earth implies a hypothesis that gravity travels at the speed of light; furthermore, we have derived and solved the propagation equation of gravity using the observation data of Earth tides from Shiquanhe and Wushi, after correction of phase lag due to the anelasticity of the Earth, and found that the speeds of gravity are from 0.93 to 1.05 times the speed of light with a relative error of about 5%.

This provides first set of strong evidences to show that the speed of gravity is the same as the speed of light.

The most interesting bit is the speed of gravity. I have never thought of gravity having a speed.

makes sense..

I like the 1.05x speed bit.

The link points to the graphene disk spinning under laser :/
