Why do Gravitational Waves Move at the Speed of Light? 0 (0)

Einstein’s theory of general relativity was the first to predict gravitational waves. The theory describes these waves as disturbances in the curvature of spacetime that move through space at the speed of light.

How Does A Black Hole Bend Time Around It? 0 (0)

Black holes are so mysterious that all the known physics break down inside them. Because they are so massive, they can drag and completely twist spacetime around themselves.

Time Travel Is Possible 0 (0)

Since relativity is our most profound theory of time, we would like to argue that time travel is forbidden by relativity. Einstein had thought that his description of space-time would forbid time travel. But this is simply wrong. Not only is time travel not ruled out but we can actually design time machines.
