Question

Summary of Stephen Hawking's Black Hole Theory in 80 words

Answer 1

Answer:

In 1976, Hawking suggested that, as black holes evaporate, they destroy information about what had formed them. That idea goes against a fundamental law of quantum mechanics which states any process in physics can be mathematically reversed. The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core.
