Speed of gravity - Wikipedia, the free encyclopedia
In the context of classical theories of gravitation, the speed of gravity refers to the speed at which a gravitational field propagates. This is the speed at which changes in the distribution of ene...

A presentation of evidence that gravity must propagate at a speed substantially faster than the speed of light. ... Indeed, it is widely accepted, even if less widely known, that the speed of gravity in Newton’s Universal Law is unconditionally infinite.

To begin with, the speed of gravity has not been measured directly in the laboratory--the gravitational interaction is too weak, and such an experiment is beyond present technological capabilities.

Efforts of National Radio Astronomy Observato ry (NRAO) scientist Ed Fomalont and University of Missouri theoretical physics p rofessor Sergei Kopeikin at measuring the speed of gravity are described. ... Sir Isaac Newton thought that the speed of gravity was instantaneous, and Einstein assumed it traveled at the speed...

Noted physicists are criticizing a report last week that suggested the speed with which gravity propagates had been determined and was equal to the speed of light. ... "The claim that they've measured the speed of gravity is simply incorrect," said Clifford Will, a physicist at Washington University in St Louis, Missouri,

The first accurate measurement ever taken of the speed with which gravity propagates shows that it is equal to the speed of light. ... You may or may not have ever considered whether gravity has speed. It is of great concern to scientists. Newton thought gravity's force worked instantaneously. Einstein thought it took effect...

The mere existence of Lorentzian relativity as an experimentally viable model for the relativity of motion nullifies the “proof” that nothing can propagate faster than light in forward time. ... We recently reviewed six experiments bearing on the question of the propagation speed of gravity. [1] Briefly, these are:

“Einstein may be correct about the speed of gravity but the experiment in question neither confirms nor refutes this,” says Samuel. “In effect, the experiment was measuring effects associated with the propagation of light, not the speed of gravity.”...
