29 June 2023
After decades of searching, astronomers have found a distinctive pattern of light, from spinning stars called pulsars, that suggests huge gravitational waves are creating gentle ripples in space-time across the universe
What the huge young galaxies seen by JWST tell us about the universe
13 June 2023

Stephen Hawking's final theorem turns time and causality inside out
20 March 2023
In his final years, Stephen Hawking tackled the question of why the universe appears fine-tuned for life. His collaborator Thomas Hertog explains the radical solution they came up with
Neil Turok on the case for a parallel universe going backwards in time
25 January 2023
To explain the cosmos without invoking cosmic inflation, physicist Neil Turok has proposed the existence of a mirror-image universe going backwards in time from the big bang. He tells us why the idea is so compelling
