Black hole
A black hole is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that...

proved that the exact asymptotic behaviour of the quasinormal modes of the Schwarzschild black hole was as predicted numerically.

Dreyer has developed an approach to quantum gravity known as "internal relativity".
