Here's the idea: As one approaches the event horizon of a black hole, gravity increases, and time slows. The outside universe appears to speed up. The rate of infalling matter increases, which is consumed by the black hole to increase it's mass. The Schwarzschild radius of the black hole varies with mass, so the black hole grows in size faster and faster. When one crosses the event horizon, the rate of infalling matter approaches infinite and the black hole sucks in the whole outside universe, and inflates to the corresponding size, which is larger than the visible universe. So the end-effect is that a black hole is a secondary explosion triggered by a supernova (like how a fission bomb triggers a fusion bomb), but which has the critical density for a chain reaction that consumes the entire universe. A space-time explosion. Opinions?
