What is the “speed” of gravity?


Hypothetically, if one remove the Sun from its place, when the Earth would be affected? Momentary, by the speed of light or by some speed specific to the gravity...?

    Yes sorry I did mean 8 Minutes and not seconds. A senior moment I'm afraid.

    I am not sure that the Earth will also move at the same time, as you say. It is reasonable to expect that it would be almost at the same time, but I am not sure if we can say so precisely. I think that this is an open problem in physics...

    Gravity is not a force. Gravity is a tension, and tension is NOT a force. Stretch a rubber band and hold. Feel the tension. There is no motion. If someone cuts the rubber band, the tension HAD BETTER disappear INSTANTANEOUSLY! It won't take 8 mins!

    Actually the speed of gravity is unknown. We are working hard to assign a value to "gravity" but it has proven elusive to all attempts. We just don't know enough, with our current physics, to solve the "mystery" of gravity.....yet!
