Using the MUSE instrument on ESO’s VLT , a team led by Thomas Collett from the University of Portsmouth in the UK first calculated the mass of ESO 325-G004 by measuring the movement of stars within ...
Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...
In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to ...
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Record-breaking gravitational wave puts Einstein's relativity to its toughest test yet — and proves him right again
Scientists have used the loudest gravitational-wave signal ever recorded to put Albert Einstein's more than 100-year-old theory of gravity to its toughest test yet — and once again, it passed. The ...
Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...

Black hole ringing could put Einstein’s theory to its toughest test
A newly merged black hole does not become quiet at once. It vibrates, sheds energy through gravitational waves and produces a ...
Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo ...
General Relativity (GR), Einstein’s theory of gravitation, underpins our understanding of the large-scale dynamics of the Universe. Over recent decades, rapid advances in observational cosmology have ...
In 1919, the English astronomer Arthur Eddington travelled to the island of Príncipe off the coast of west Africa to see if he could detect the lensing of light predicted by general relativity. His ...
