Gravitational waves

It’s been dubbed the heavyweight champion of black holes. But the first image of the M87* black hole also provides us with a treasure trove of information about our Universe

To celebrate 50 years of the July Lectures in Physics, we look back at four physics discoveries that have changed the world

Professor Stephen Hawking changed the way we understand the universe and leaves a legacy of theory ranging from black holes to the quantum effect on time

Scientists have just confirmed that their third observation of gravitational waves was a success. But what are gravitational waves? And why are astronomers jumping up and down with excitement?

Einstein was right all along. The discovery of gravitational waves proves the universe is talking to us – and listening to it will take us to places we’ve never been before
