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 ...
A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.
New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems, relativistic effects cause orbital resonances that destabilize planets, ...
