White hole Welcome to my blog “ Mystery of Galaxy” . An artistic representation of a white hole. Source: NASA’s Goddard Space Flight Center/Discover From the mathematics of Einstein’s general relativity comes an object so peculiar, a white hole. The white holes twin of a black hole, was first thought of in the 18th century by the geologist John Mitchell . In those days, black holes were not considered to be real, Einstein even assumed they didn’t exist. Yet Einstein’s theory of general relativity predicts and allows a concept named a white hole. More specifically it’s the mathematics of general relativity that say that white holes are possible. If you take the mathematics of a black hole and literally reverse it, you get a white hole. Or even, a white hole is a time-reversed blackhole. So, a black hole will not allow any matter to escape, once the matter is cross the event horizon, an imaginary boundary around a blackhole where no matter can escape after passing it. And ...
