Professor Stephen Hawking

Professor Stephen Hawking delivers this year’s BBC Reith Lectures on black holes.

Professor Hawking takes us through the history of scientific thinking about black holes, and explains how they have posed tough challenges to conventional understanding of the laws which govern the universe. He also poses (and more importantly, explains) the question: Do black holes have no hair?

The programmes are recorded in front of an audience of Radio 4 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 question-and-answer session with Professor Hawking. Radio 4 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.

The lecture can be heard in two parts:

Tue 26 Jan at 9am: Stephen Hawking: Do black holes have no hair?

Tue 2 Feb at 9am: Stephen Hawking: Black holes ain't as black as they are painted
