Explainer: making waves in science

We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?

Good vibrations: the role of music in Einstein’s thinking

Einstein, an accomplished violinist, claimed that, had he not pursued science, he would have been a musician. That's worth reflecting on, in the wake of last week's discovery of gravitational waves.

Gravitational waves add a new note to our musical universe

Music has always played a role in our understanding of the universe. Listening to gravitational waves confirms thousands of years of metaphysical investigation.

Australia’s part in the global effort to discover gravitational waves

The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?

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 discovered: the universe has spoken

The detection of gravitational waves is the final confirmation of Einstein's theory of general relativity, and opens up a new window into the cosmos.
