We’ve seen our galaxy’s huge black hole more clearly than ever before
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
X-rays can echo and bend around the back of supermassive black holes
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
A warp drive that doesn't break the laws of physics is possible
3 March 2021
Previous ideas for warp drives have required types of matter that do not seem to exist, but a new concept could allow them to be made without any imaginary substances
Travelling through a wormhole without dying may actually be possible
31 August 2020
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
The fastest star in our galaxy moves at 8 per cent the speed of light
14 August 2020
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
Einstein was right about how extremely massive objects fall in space
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
The orbit of a star near our galaxy’s black hole proves Einstein right
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
Two stars with an odd wobble are stretching space and time around them
30 January 2020
Einstein’s theory of relativity predicts that fast-spinning objects stretch space and time around them, and we’ve watched that effect make a pair of stars wobble
Black hole that 'rings' like a bell shows Einstein was right
16 September 2019
Astronomers have looked at the way a black hole 'rings' like a bell to test a prediction of Einstein’s general relativity. Turns out Einstein is still right
