Latest about theory of relativity
Einstein's Theory of Special Relativity
By Vicky Stein last updated
Einstein's paper on special relativity revolutionized light, light speed, matter and energy with a deceptively simple equation.
Curvature of space-time measured using 'atomic fountain'
By Rahul Rao published
A group of physicists has measured gravity using the effects of time dilation — the slowing of time imparted by increased velocity or gravitational force — on atoms.
Einstein's theory of general relativity passes one of its toughest tests yet
By Mike Wall published
Scientists tested seven different predictions, in one of the most ambitious and involved challenges to general relativity ever undertaken — and the theory passed with flying colors.
Einstein's core idea about gravity just passed an extreme, whirling test in deep space
By Rafi Letzter published
Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity and relativity — this time with the help of a neutron star flashing across space.
Why physicists are determined to prove Galileo and Einstein wrong
By Yasemin Saplakoglu published
Physicists dropped objects on a satellite for two years to test Galileo's theory of falling objects.
Move Over, Einstein! 'Chameleon' Theory Provides Alternate Explanation for Cosmos Formation
By Passant Rabie last updated
Scientists created a computer simulation to test an alternative theory to the evolution of the cosmos.
Einstein's Gravitational Lenses Could Clear Up Roiling Debate on Expanding Cosmos
By Charles Q. Choi published
Warps in the fabric of space-time can act like magnifying glasses, and that may help solve a cosmic mystery about the rate of the universe's expansion, a new study found.
'Supergravity' Theorists Win $3 Million Physics Breakthrough Prize
By Mike Wall published
The three architects of supergravity are getting some high-profile recognition, more than four decades after they developed the influential theory.
