Some habitable worlds orbiting dead stars could be kept alive for aeons thanks to a quirk of Einstein’s theory of gravity ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is ...

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, ...

Understanding singularities is key to resolving gaps in physics, with theories like string theory and causal set theory ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time.

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...
