By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe.

At the heart of our galaxy lies a monster so deadly it can bend space, throwing vast jets of radiation millions of light years out into the cosmos. Its kind were the very first inhabitants of the universe, the black holes.

Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole - heating it to millions of degrees as it is shredded at the event horizon.

They have the power to wipe out any of the universe's other inhabitants, but no one has ever seen a black hole itself die. But 1.8 billion light years away, the LIGO instruments have recently detected something that could be the closest a black hole gets to death. Gravitational waves given off as two enormous black holes merge together. And now scientists think that these gravitational waves could be evidence of two black holes connecting to form a wormhole - a link through space and time. It seems outlandish, but today's physicists are daring to think the unthinkable - that black holes could connect us to another universe.

At their very heart, black holes are also where Einstein's Theory of General Relativity is stretched in almost unimaginable ways, revealing black holes as the key to our understanding of the fundamentals of our universe and perhaps all other universes.

Join Professors Brian Cox and Jeff Forshaw in exploring our universe's most mysterious inhabitants, how they are formed, why they are essential components of every galaxy, including our own, and what secrets they still hold, waiting to be discovered.

Forshaw, Jeff

Jeff Forshaw, Ph.D., is Professor of Theoretical Physics at the University of Manchester, specializing in the physics of elementary particles. In 1999 he was awarded the Institute of Physics Maxwell Medal for outstanding contributions to theoretical physics. He is the coauthor of five books on science with Brian Cox.

Cox, Brian

Brian Cox, Ph.D., is Professor of Particle Physics at the University of Manchester. Dr. Cox is also a Royal Society research fellow and a researcher on the ATLAS experiment on the Large Hadron Collider in Switzerland. He is perhaps best known as a science broadcaster and host of the BBC's hugely popular Wonders series. He is the coauthor of three companion books to these series, which have become #1 Sunday Times bestsellers, as well as two narrative works of popular science, The Quantum Universe and Why Does E = mc2? In the 1990s he played keyboards for the UK pop band D: Ream.
