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 ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in ...

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 ...

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 ...

This is an example of time dilation, a consequence of the idea that time and space are not absolute - meaning all observers do not always measure these quantities as the same. In everyday life we use ...

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

Tachyons are a hypothetical particle generally thought to be incongruous with Einstein's theory. New measurements from an experiment near the top of an extinct Mexican volcano have placed a stringent ...
