Albert Einstein was born on this day in 1879. As part of his Theory of General Relativity he predicted the existence of gravitational waves, ripples in the fabric of space time caused by massive events like the collision of two black holes. The search to find evidence of them took 100 years but last month the scientists at the Laser Interferometer Gravitational Wave Observatory (LIGO) announced they had done just that, recording the result of two black holes colliding 1.3 billion years ago.

Black Hole Blues by Janna Levin tells the inside story of this fascinating search; a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.
