Scientists claim hairy black holes explain Hawking paradox
[BBC] Scientists say they have solved one of the biggest paradoxes in science first identified by Prof Stephen Hawking.He highlighted that black holes behave in a way that puts two fundamental theories at odds with each other. Black holes are dead stars that have collapsed and have such strong gravity that not even light can escape. New research claims to have resolved the paradox by showing that black holes have a property which they call "quantum hair". "The problem has been cracked!" Prof Xavier Calmet of the University of Sussex, told BBC News exclusively, with much satisfaction. He was among those who developed the mathematical techniques they say has solved the paradox. At the heart of the paradox is a problem which has threatened to undermine two of physics most important theories. Einstein's general theory of relativity says information about what goes into a black hole cannot come out, but quantum mechanics says that is impossible. Posted by: Skidmark 2022-03-18 |
