Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

relativity established by theoretical physicist Albert Einstein is an important theory that is the basis of modern physics, but there is also an image that it is related to complicated phenomena such ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

A new study validates Einstein's theory of general relativity in a distant galaxy for the first time. This study supports our current understanding of gravity and provides more evidence for the ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

For the first time ever, researchers have watched a star race past the supermassive black hole at the heart of the Milky Way, verifying that its motion showed the effects of general relativity, as ...
