Physicist and popular scientist Professor Jim Al-Khalili talks about his new BBC Four documentary, Gravity and Me: The Force that Shapes our Lives, and introduces some preview clips from the film.

Al-Khalili and a team of fellow scientists and volunteers carried out a series of experiments that reveal where we can go if we want to weigh less, and how the rate at which we age and the speed at which we move is affected by gravity. He visited the LIGO interferometer telescope in Louisiana where gravitational waves predicted by Einstein a century ago were detected for the very first time earlier this year, and he recreated the first experiments on gravity carried out by Galileo.

Al-Khalili is a professor of physics and chair in the public engagement in science at the University of Surrey. He is a broadcaster and author of popular books about science including Paradox: The Nine Greatest Enigmas in Science and Life on the Edge: The Coming of Age of Quantum Biology. He is a regular presenter on television including of documentaries in the BBC Horizon series.
