The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally dreamed up to help untangle paradoxes in quantum theory and relativity.

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 limits of Einstein's relativity, but they also seemed to wreck the basic order ...
