Albert Einstein's theory of general relativity, which suggests that gravity is due to the curvature of space and time, is more than 100 years old. Our observations are consistent with Einstein's theory of general relativity. It cannot fully explain gravity inside a black hole, and at some point we will need to move beyond Einstein's theory to a more comprehensive theory of gravity that explains what a black hole is." We asked how gravity behaves near a supermassive black hole and whether Einstein's theory is telling us the full story. The researchers were able to see how space and time commingled near the black hole, she said.
