Space-time isn't expanding into anything because general relativity is what we call a background independent theory. Chanda Prescod-Weinstein sets out to explain what this means

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

After monitoring a pair of pulsars in tight orbit around one another for 16 years, astronomers conclude that their behaviour is consistent with Einstein’s predictions

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

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

10 June 2020
A crucial pillar of Einstein’s theory of general relativity has been tested with the motion of stars at the highest precision yet, and the theory has held up once again

16 April 2020
A star that swoops close to the Milky Way’s supermassive black hole has a strange, looping orbit that proves Einstein was right about the gravity of black holes
