Why Do Tachyons Exist

Tachyon particles are theoretical particles that supposedly have a minimum speed of the speed of light. Tachyons, (from the greek word ‘tachys’, meaning swift), have never been found in experiments, but scientists think that they exist as faster-than-light “quasiparticles”. In the 1960s, some physicists wondered what would happen if matter could travel faster than the speed of light, something that is supposed to be impossible according to Einstein's Theory of Special Relativity. Tachyons were first mentioned by by physicist Arnold Sommerfeld, and they were named by Gerald Feinberg.

Tachyons can have properties of normal matter like spin, as well as an antiparticle (the antitachyon).Tachyons appear to violate causality, because they can be sent to the past assuming the Theory of Special Relativity is true, this creates a time paradox. Therefore, it seems that if Tachyons do exist, the Theory of Special Relativity must be false, “and there exists a unique time order for all observers in the universe independent of their state of motion.” quoting scienceworld.wolfram.com.
In 1973, Philip Crough and Roger Clay found a putative particle in an air shower, although this result has never been found again. Tachyon particles have some strange properties such as when Tachyons are losing energy, they are gaining speed. When they are gaining energy, they are losing speed. Tachyons supposedly go faster than the speed of light, which could be possible due to the fact that Tachyons have an imaginary mass. The slowest speed a Tachyon can go is the speed of
