The Sky at Night - Stephen Hawking on Black Holes
Stephen Hawking on Black Holes: The programme looks at the latest understanding of black holes, featuring an interview with Stephen Hawking. Black holes are one of the greatest mysteries in the universe. They behave in a way that is contrary to laws of physics and one has never actually been seen. However, the recent detection of gravitational waves, as predicted by Einstein, proves that black holes exist and provides a way to investigate their remarkable behaviour and properties. Stephen Hawking made headlines back in January 2016 when he told the world he'd found a possible solution to his black hole information paradox. Or in other words, he'd come up with a potential explanation for how black holes can simultaneously erase information and retain it. Our original understanding of black holes, according to Einstein's generally theory of relativity, is that everything that crosses the event horizon - the boundary of a black hole - is lost forever. Even light can't esca
