Understanding the speed of gravity is the holy grail of astronomy and physics. Finally, with advanced gravitational waves detection technology and equipment, scientists have been able to further narrow down the speed of gravity relative to “c,” the speed of light in vacuum.

The new observations from a space-warping merger of neutron stars, which prove that the speed of gravity and speed of light are practically same, not only boost our understanding of the cosmos but debunk theories challenging Einstein’s general relativity, writes Futurism.  

In the absence of a direct means of measurement, the speed of gravity has been treated between 55 and 142 percent of “c,” since Albert Einstein refuted Newton’s theory that gravity was an instantaneous force, notes Science Alert
