In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Einstein’s famous tenet of special relativity — that time slows down on a moving clock — has been verified 10 times more precisely than ever before. The result comes from physicists in Germany and ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at ...

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 ...

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars -- collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the ...
