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 ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared ...

Ever since Einstein: nothing is faster than light. In 2011, an experiment at CERN seemed to prove the opposite - until the ...

Noether discovered that for every continuous symmetry of a system, there is a conserved quantity—that is, a quantity that ...

How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. "We should expect to see not only phenomena ...

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...
