Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Physicists picture light and other electromagnetic radiation as arising from underlying symmetries in subatomic particles and force fields. But Robert Bluhm of Colby College in Maine and Alan ...

All observations in astronomy are based on light (electromagnetic radiation) emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity.

The Sagnac effect, first observed over a century ago, remains central to our understanding of relativistic kinematics and the operational definitions of simultaneity. Fundamentally, this effect arises ...

To make the admittedly weird concept of relativity easier to understand, a team of developers has created a video game that slows down the speed of light. Relativity is the theory that space and time ...

Particles that move faster than c might sound like pure sci-fi, but it wouldn't be as hard to square with current physics as you might think. By now you’ve probably heard the widely reported news ...

A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. So it turns out that Einstein may not have been wrong about the ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...
