Black Holes: Not as Black as They Are Painted

Professor Stephen Hawking delivers the second of his 成人快手 Reith Lectures on black holes.

Professor Stephen Hawking examines scientific thinking about black holes and challenges the idea that all matter and information is destroyed irretrievably within them. He explains his own hypothesis that black holes may emit a form of radiation, now known as Hawking Radiation. He discusses about the search for mini black holes, noting that so far "no-one has found any, which is a pity because if they had, I would have got a Nobel Prize." And he advances a theory that information may remain stored within black holes in a scrambled form.

The programmes are recorded in front of an audience of 成人快手 Radio listeners and some of the country's leading scientists at the Royal Institution of Great Britain in London. Sue Lawley introduces the evening and chairs a Q&A session with professor Hawking. 成人快手 Radio listeners submitted questions in their hundreds, of which a selection were invited to attend the event to put their questions in person to professor Hawking.
