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 artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

The method involves stitching together many thin “slices” of light reflecting off an object.

For the first time in history, scientists have succeeded in visually capturing the speed of light. Through an innovative use of high-speed photography and lasers, researchers have managed to ...

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. Tachyons are a ...

BLOOMINGTON, Ind. -- Light as we know it may be a direct result of small violations of relativity, according to new research scheduled for publication online Tuesday (March 22) in the journal Physical ...

When an object moves extremely fast – close to the speed of light – certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special ...

Relativistic physics imposes one of the most frustrating limitations predicted by science. It tells us that an inescapable speed limit exists in the universe: we can't go faster than the speed of ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of ...
