Gravity has a speed of light

Chinese scientists claim to have found important evidence for the hypothesis that gravity moves at the speed of light, based on data collected from the tide.

Over the years, the scientific community has been constantly trying to measure the speed of gravity, but it is rare for people to find the right measures to implement the research.

Observation eclipse observations to complement this finding

By observing six solar eclipses and total solar eclipses, as well as tidal phenomena on Earth, the team led by Tang Keyun of the Chinese Institute of Geology and Geophysics discovered one point Important, Newton's tidal formula includes an element related to gravitational transmission, according to Xinhua.

Since then, the team determined the gravitational pull from the sun and the force recorded at stations on Earth did not move at the same speed.

They say observatories are usually located near the sea, indicating the influence of tides strong enough to influence the results recorded on the ground.

Therefore, the team of experts conducted tidal observations at 2 stations in Tibet and Xinjiang, 2 areas far away from the oceans, as well as taking measures to filter out the external impacts. .

When applying new data to the gravitational equation, the team found the velocity of gravity to be between 0.93 and 1.05 times the speed of light, with an error of about 5%.

The result is the first strong evidence that gravity moves at the speed of light.
