(G * m1 * m2) / (d2) = 300000kps/186000mps
One thing that Einstein was wrong about was the speed of light, researchers have shown that light does not in fact travel at a constant speed, so the original idea of it travelling at it’s estimated speed is incorrect, so with that in mind they could not have mapped the speed of gravity, as no one can know what the true speed of light actually is.
The idea is, is that if you peer back far enough see the origins of the big bang, at this point light travelled much faster, and as the universe expanded it became slower, but from our point of view light travels to us at a constant speed, but that is only from our vantage point on Earth, and we caculated it fronm the Earth, so light is not a constant in other parts of the universe, so in essence they have only mapped the speed of gravity on how we perceive the speed of light…it is by no means a universal constant.
