tachyon Physics.|ˈtækɪɒn|
[f. tachy- + -on1.]
A hypothetical particle that travels faster than light and has imaginary mass. Hence tachyˈonic a.
1967G. Feinberg in Physical Rev. CLIX. 1090/1 One description is presented..for noninteracting faster than light particles, which we call tachyons. 1970Sci. Amer. Feb. 70/2 Hence a tachyon that was losing energy by interacting with matter or by radiating light would speed up, whereas a tachyon that was gaining energy from some outside source would slow down, and its speed would approach c from above rather than below. 1970Physical Rev. D II. 265/2 (caption) A and B use tachyonic anti⁓telephones to communicate backwards in time. 1974Globe & Mail (Toronto) 13 Apr. 5/1 The pursuit of the elusive tachyon lures scientists into the realm of complex mathematical abstraction and high-flown theoretical physics. 1978Pasachoff & Kutner University Astron. xxvii. 695 So far, there is no experimental evidence that tachyons exist. |
