For the relativistic formula for the kinetic energy, ordinary subatomic particles are confined in an infinite well of velocity of Light [c]. So it may be however considered that Faster than Light Particle (FTL) speed phenomenon may exist in this Universe. On the other hand to day even physicists and particle physicist do not consider that Faster than light particles (FTL) exists. The FTL particle is called “Tachyons” the name coined by G. Feinberg [8] in 1969. There had been many search by various experiments for FTL but most of them showed negative for their existences. It may be that light particles created inside the atomic nuclei which has the nonzero rest mass less than 10-32 kg has the probability of almost unity to transfer into FTL. The electron neutrinos and muon neutrinos also have been observed as FTL state but they have mass and if the rest mass of the neutrinos emitted in proton smashing at speed of light is less than 10-32 then it may be travelling as FTL and there is possibility of existences of Tachyons.
