Researchers are building models of everything from black holes to the big bang in tanks of liquid. Now some claim these surprisingly simple models are showing us where our theories of space-time are wrong

A pair of merging black holes show extreme signs of gravity-induced orbital precession, or wobbling, as predicted by Albert Einstein's theory of general relativity

A few particles of light bouncing off a flying mirror made of charged particles may reveal whether or not black holes destroy information, a famous problem in physics

The Event Horizon Telescope collaboration has released the first picture of our galaxy’s supermassive black hole, Sagittarius A*, and it’s just as predicted
14 December 2021
Astronomers have observed Sagittarius A* – the supermassive black hole at the centre of our galaxy – closer than ever before, and Albert Einstein’s general theory of relativity still holds up
28 July 2021
Flashes of X-rays have been spotted echoing from behind a supermassive black hole, confirming one of the predictions of Albert Einstein’s general theory of relativity

Most of the wormholes that could theoretically exist cannot be traversed, but adding an extra dimension makes it possible to make one you could pass through without dying

Ever wondered what a black hole is made of, or what would happen if you fell into one? Let our new video series Science with Sam explain everything.

Astronomers have spotted the fastest star ever, whizzing at 8 per cent the speed of light around our galaxy’s supermassive black hole closer than any star we’ve seen before

Black holes exert a powerful pull on our imagination, but their weirdness starts way before you cross the event horizon, says astrophysicist Chris Impey
