New research suggests that a perplexing signal created by a pair of colliding black holes may have been warped by a ...

Einstein’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks begin to appear. Physicists have identified a gap Einstein never had the tools ...

In the end, the measured phase of the quantum wave sits 2.5 percent from the theoretical prediction. The result, the team argues, is a checkpoint on the border between Einstein’s relativity and ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

Most of us don’t hear a whale call and think, ‘Wow, look at the special theory of relativity in action.’” Tachyons are a hypothetical particle generally thought to be incongruous with Einstein's ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

The weak-equivalence principle is integral to general relativity, so these test results offer yet more support for a core theory of our universe. In 1916, Albert Einstein dared to declare that Isaac ...

A rare manuscript featuring early calculations that led to Albert Einstein's general theory of relativity sold for just over $13 million at an auction in Paris Tuesday, becoming the most expensive ...

Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity more than a century ago. This theory forms the basis of most of what we ...
