Comment on What is the Speed of Gravity?parentComments−ars16yThat's not how you add speeds in a relativistic world.If something is moving at the speed of light, then light (or gravity) is emitted from it also at the speed of light.But if you add the two together, it doesn't equal twice the speed of light. Yes, I know it's weird, but that's where the whole time dilation comes in.
