The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated. This optical illusion results from the combination of relativistic length ...

The idea that objects contract in length when they travel near the speed of light is a widely accepted consequence of Einstein’s special relativity. But if you could observe such an object, it ...

Researchers at Osaka University demonstrate the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. The ...

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?

A snapshot of relativistic motion: Experimental data on the Terrell rotation of a deliberately Lorentz contracted sphere at 0.999 c, moving from right to left. (Courtesy: Dominik Hornof et al., "A ...

Observing the effects of special relativity doesn't necessarily require objects moving at a significant fraction of the speed of light. In fact, length contraction in special relativity explains how ...

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. Albert Einstein's 1905 theory of special ...

Relativity is one of the most famous scientific theories of the 20th century, but how well does it explain the things we see in our daily lives? Formulated by Albert Einstein in 1905, the theory of ...

At present, mainstream physicists seem to have fully accepted Einstein's Special Theory of Relativity (STR) and to take it as the foundation of modern physics because the theory appears perfectly ...
