Second detection heralds the era of gravitational wave astronomy

The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.

Timeline: the history of gravity

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.

Gravitational waves found: the inside story

It is the physics discovery of the century – even bigger than the Higgs Boson. Here's how it happened and what it means, by a key member of one of the lead teams
