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

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 ...

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 ...

What if the technology you use every day depends on a subtle distortion of time itself? The answer lies in a century-old idea ...

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 ...

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 ...

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

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 ...

One of the fundamental tenets of Einstein’s special theory of relativity is that the laws of physics are the same regardless of your vantage point. New research suggests a way to probe for cracks in ...
