On 14 September 2015, gravitational waves were first detected on Earth. The source – two merging black holes – briefly pumped out 50 times more power than all the stars in the Universe together. Gravitational waves are the ‘voice of space’. Join science writer and broadcaster Marcus Chown, author of The Ascent of Gravity, to discover how, after centuries of ‘seeing’ the Universe, we are now ‘hearing’ it.
