In 1915, Einstein proposed that gravity actually distorts the fabric of space. His calculations perfectly explained certain astronomical observations that Newtonian physics could not account for – ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. When you purchase through links on our site ...

In 1905, Einstein's groundbreaking work showed that the speed of light in a vacuum is independent of the motion of all observers, and the laws of physics are the same for all so-called ...
