Is It a Paradox That Nothing Can Move Faster Than the Speed of Light?
Gravity travels at the speed of light as well. That's something Einstein's theory, general relativity explained as well. And it's the speed that say those gravity waves that we were talking about before in terms of these LIGO experiments that detect gravitational waves. That's the speed they also travel at. So it's very interesting that we didn't know that for sure. It was a prediction of Einstein's general relativity.
