according to the theory of General Relativity proposed by Albert Einstein, the speed of gravity is believed to be equal to the speed of light in a vacuum. This means that gravitational effects, like the force of attraction between massive objects, propagate through space at the speed of light.
However, it's important to note that our understanding of gravity and the universe is continually evolving, and there might be refinements or new theories that emerge in the future. Experimental evidence and observations have provided substantial support for Einstein's theory of General Relativity, but there are still ongoing efforts to study and test gravity at different scales and under extreme conditions to verify and explore the nature of gravitational interactions further.
Until new experimental evidence or a more comprehensive theory is established, the equality between the speed of gravity and the speed of light remains a fundamental tenet of General Relativity.
