Comment on What is the Speed of Gravity?Comments−wccrawford16yMy first thought was 'Find a way to create some matter and we'll measure it', but apparently they have a way. ;)−Locke168916yYour trouble is on focusing on the analogy too much. Instead of, "how can we measure what the effects of gravity would be if matter or energy were created or destroyed?" ask "how can we measure the movement of the curvature of spacetime?"
