As part of our celebration of the International Year of Astronomy 2009 we brought you the article How does gravity work?, in which Bangalore Sathyaprakash takes us from Newton's theory of gravitation to Einstein's general theory of relativity. Now hear Sathyaprakash explain gravity in his own words in this podcast.
If this has whetted your appetite for astronomy, then why not take part in our current online poll to nominate the next question we'll put to the experts.
