Document Summary

Sometimes the gravity in a stellar corpse becomes so strong that nothing can prevent the. The stellar corpse collapses without end, crushing itself out of existence and forming a. Already known from newton"s laws that the escape velocity from any object depends. Einstein"s theory of relativity: eventually shows that black holes are considerable. Idea of bh first suggested in late 18th century by john michell (british philosopher) and. Pierre laplace (french physicist) ! speculated about objects so compact that their escape velocity exceeds the speed of light stranger than michell and laplace though, but basic idea was correct. It is indeed possible for an object"s gravity to be so strong that not even light can escape. The event horizon: boundary around a black hole at which the escape velocity equals the speed of light. The even horizon: the boundary between the inside of a black hole and the universe.
