What is a Black Hole? How many are there in the Universe? How are they formed? What size are they and what would the consequences be if we were able to travel to a Black Hole?

To answer these questions and many more join me in conversation with Marcus Chown, an award-winning writer and broadcaster. Formerly a radio astronomer at the California Institute of Technology in Pasadena, he is a Royal Literary Fund Fellow at Brunel University. His books include The Ascent of Gravity, which was The Sunday Times Science Book of the Year; and he has just brought out his latest book A Crack in Everything: How Black Holes Came in From the Cold and Took Centre Cosmic Stage. As well as writing, Marcus was a regular guest on the BBC4 comedy-science show, It’s Only A Theory, and often appears on Channel 4’s Sunday Brunch.
