Albert Einstein's theory of general relativity—which explains gravity ... What "3 sigma" means, Grimm explained, is that the difference is interesting and merits further investigation.

The study says that the gravitational distortions observed in distant galaxies exhibit subtle discrepancies with the ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger ...

In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating ...

The accelerating expansion of the Universe has puzzled scientists since its discovery in 1998. This phenomenon, one of the ...

Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory ...

The instrument is creating the largest map of the universe. In mapping, it revealed how large cosmic structures stick ...

The Dark Energy Spectroscopic Instrument (DESI) has made significant contributions to understanding the universe's structure over the past 11 billion years, confirming Einstein's theory of general ...

After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a ...

Once again, scientists have proven Einstein's theory of general relativity is indeed correct using a Dark Energy Spectroscopic Instrument (DESI). By using the DESI to observe how dark energy and ...

it’s actually by far the weakest of the four known forces of nature – and the only one not explained by quantum theory. Quantum theory and general relativity in fact don’t get along at all.

Four familiar physicists – Brian Cox, Helen Czerski, Tara Shears and Jim Al-Khalili – explain why Einstein's theory of general relativity still matters to them. Click or tap on the labels ...
