Astronomers have explained a strange effect observed in the vicinity of black holes.

Finally we can be sure — black holes, those gravitational monsters that gobble up everything that gets too close to them, do exist.

Physicists have finally detected the gravitational waves they have been chasing for nearly 100 years.

It's impossible not to be fascinated by black holes. Find out all you'd like to know about them with these articles, videos and podcasts.

A hundred years ago, on 25 November 1915, Einstein first presented his general theory of relativity. We explore this famous theory and what it says about the world we live in.

Pau Figueras explains how Einstein's theories predicted the existence of black holes, and how to describe them mathematically.

Small, dark, and very hard to see. This and far more indepth answers to every question you ever wanted to ask about black holes.

We asked cosmologist Pau Figueras everything we’ve ever wanted to know about black holes. In this podcast he explains what black holes are, physically, and how we hope to observe them.

Why there is a limit to how much better computer chips can get and what it's got to do with black holes.

In 2004 Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter — seemingly resolving the black hole information paradox that had perplexed physicists for decades. But some argue that the paradox remains open and we must abandon our simple picture of spacetime to unravel it.
