Using Einstein's theory of general relativity, physicists found that clocks on the moon would run 56 microseconds faster than ...

"Studying the rate at which galaxies formed lets us directly test our theories and, so far, we’re lining up with what general ...

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

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

The largest survey of our universe ever conducted suggests that it closely matches the model most favored by cosmologists. It ...

An international research team's new calculations of the distortion of time and space presents new challenges to predictions ...

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 ...

DESI’s data isn’t limited to testing theories of gravity. It also emphasizes neutrinos, particles so tiny and elusive their ...

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