Tachyon: A hypothetical particle Here we are with 5 fascinating facts about Tachyon Particle. So let's start:- Q.1:- W hat is a tachyon particle? A:- A tachyon or tachyonic particle is a hypothetical particle that always travels faster than light. Most physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics. Q.2:- Can Tachyons exist? A: - No experimental evidence for the existence of such particles has been found Q.3:- Who discovered Tachyons? A:- The possibility of particles moving faster-than-light was first proposed by O. M. P. Bilaniuk, V. K. Deshpande, and E. C. G. Sudarshan in 1962, although the term they used for it was "meta-particle Q.4:- Can we see tachyon? A:- Because a tachyon would always travel faster-than-light, it would not be possible to see it approaching. After a tachyon has passed nearby.
