How fast do they travel across the universe? Gravitational waves travel at the speed of gravity! It is through the work of LIGO, Virgo, and observations from other astronomers that we learned that the speed of gravity is equal to the speed of light. Einstein predicted this, but our exciting...
In summary, gravitational waves are ripples in spacetime caused by the acceleration of massive objects, such as merging black holes or neutron stars. Predicted by Albert Einstein's general theory of relativity, these waves travel at the speed of light and can be detected by sensitive instruments ...

The big discovery we're experiencing now has to do partly with this direct observation, for the first time, of gravitational waves, emitted directly from a black hole, and being detected directly by instruments on the earth. SHANE LARSON: The structure of the universe has a shape to it. An...
More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical ph...
