The world’s most precise atomic clock has confirmed that the time dilation predicted by Albert Einstein’s theory of general relativity works on the scale of millimetres. Physicists have been unable to ...

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...

In the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, researchers report that Einstein's theory of general relativity holds up, at least for ...

Score one more for Einstein. A new study has confirmed histheory of general relativity works on extremely large scales. The study was one of the first rigorous tests of this theoryof gravity beyond ...

Chalk up another win for Einstein’s seemingly invincible theory of gravity. A new study shows that the theory of general relativity holds true even over vast distances. Using the observations of ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...
