Einstein's special relativity emerged independently, challenging misconceptions about the Michelson-Morley experiment's ...

A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not ...

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 theory ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...

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 ...

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 ...

In a recent paper [1], the author shows that in spacetime physics, the Selleri transformations (STs) are viable alternatives ...

University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light. Einstein’s theory holds that nothing could move faster than the ...

Albert Einstein's general theories of relativity have been used to create tiny microscopic robots that can essentially "swim" ...
