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 ...

(Inside Science) — Just six years ago, scientists with the Laser Interferometer Gravitational-Wave Observatory, or LIGO, in Louisiana and Washington measured a unique undulating signal when 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 ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

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 ...

Einstein's theory of general relativity may be over 100 years old, but a 16-year-long investigation of extreme stars has shown that it is still the best description of gravity we have. An ...

Einstein's general theory of relativity has passed its toughest test yet. By looking at a pair of neutron stars — the densest objects in the Universe after black holes — scientists have made the most ...

Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century. The team behind the ...
