I heard somewhere that gravity behaves much like waves. That must mean that gravity has a speed, right?
Does that mean that is the sun suddenly dissapeared, the planets in our solar system would continue to move in their previous orbits until the end of the waves reaches them?
Then, if two planets by chance were properly alligned to each other, then one might start going in a straight live before the other, and the other, who is still moving in an orbit, moves in such a way that the two planets collide with one another or start to go in orbits around each other?
