McGucken’s light cone artwork started with some 3D printing of the cones. But then, a few months ago, he got the idea of representing them with a drone—or, as he says, “painting with light.” ...

THE fundamental postulate of the special theory of relativity, ... That is to say, it is asserted that causal links and links of information outside the light cone do not exist, ...

What is relativity? Succinctly put, it is the notion that the laws of physics are the same everywhere. We here on Earth obey the same laws of light and gravity as someone in a far off corner of ...

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.

A light-speed event requires an even faster camera. A new camera setup has captured the first film of a photonic Mach cone – basically, a sonic boom with light – in real time.

Special relativity is also based on a second assumption that gives the speed of light — 186,000 miles per second (300 million meters per second) — in a vacuum a special status.

The results, published March 22 in the journal Physical Review D, show this new description of light is a general feature of relativity violations: ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible.

No, this isn't an Allman Brother's show. It's a screen shot from a video game called A Slower Speed of Light that helps teach the concept of relativity.
