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 ...

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 ...

The MICROSCOPE mission tested the weak equivalence principle with free-falling objects in a satellite. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Albert Einstein's theory of general relativity, which suggests that gravity is due to the curvature of space and time, is more than 100 years old. And it's holding up as researchers analyze the ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

The mathematics Albert Einstein devised to describe the gravitational workings of the physical Universe in the early 20th century is still holding strong. In one of the biggest tests of general ...

In new studies published in Physical Review Letters and a special issue of Classical and Quantum Gravity on September 14, a team of researchers present the most precise test yet of the Weak ...

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 ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...
