Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Scientists studying radiation from a distant gamma-ray burst have found that the speed of light does not vary with wavelength down to distance scales below that of the Planck length. They say that ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

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 ...

Well connected: an optical clock at PTB was used in the comparison. (Courtesy: PTB) Atomic clocks in France, Germany and the UK have been used to perform the best-ever confirmation of time dilation as ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...
