The Kerr-Metric: describing Rotating Black Holes
... In 1795 Laplace proposed, using Newton’s theory of gravity, it was possible for very dense and massive objects to have an escape velocity larger than the speed of light. Not even light could escape from such an object: it would appear black. In 1915 Einstein published his famous theory of general re ...
