Definition of tachyon in English:

tachyon

noun ˈtakɪɒnˈtækiˌɑn

Physics

A hypothetical particle that travels faster than light.
〔物理〕超光速粒子
Example sentencesExamples
- Small subatomic particles such as photons, particles of light, and hypothetical particles called tachyons seem to have no problem reaching light speed.
- The biggest problem with bosonic string theory (aside from the lack of fermions) is that the lowest energy state was a tachyon, or a particle mode with negative mass squared.
- That brings me to the next interesting point - one way to view the momentum of tachyons is to consider that they have imaginary mass.
- The existence of tachyons is allowed by the equations of Einstein's special theory of relativity.

Origin

1960s: from tachy- 'swift' + -on.
