Black Holes - The (w)hole story

About the clips

A Black Hole is a cosmic body that is so massive that it warps space-time around it. Even light, the fastest thing in the universe cannot escape from it. The ordinary laws of physics do not work beyond the event horizon of a black hole. Giant black holes are formed in the centers of galaxies and can have billions of sun masses. Our own Milky Way has a giant black hole in the centre!

On 14 September 2015 black holes were directly observed for the first time. The source of the first gravitational waves ever detected on that day came from a pair of black holes merging to form a single larger black hole. Watch the whole story of black holes in a series of 14 short interviews with famous scientists from all over the world, for whom black holes are their work and their passion.

Black holes: no phenomenon is stranger, no reality less tangible. Einstein rejected them, astronomers tried to ignore them. But today black holes are a fundamental part of the way scientists understand our universe. gives you the whole picture.

Find out what black holes are and how astronomers observe them. Learn how physicists "experiment" with them using the world's fastest supercomputers, how astronomers hope to listen to black holes directly using huge gravitational wave detectors and why scientists no longer have Einstein's doubts about black holes.
