Do tachyons really exist?
Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light ‘quasiparticles’ moving through laser-like media. “We are beginning an experiment at Berkeley to detect tachyon-like quasiparticles.
Who discovered Tachyons?
Gerald Feinberg
Tachyons were first introduced into physics by Gerald Feinberg, in his seminal paper “On the possibility of faster-than-light particles” [Phys. Rev. 159, 1089—1105 (1967)]. E = m[1−(v/c)²]−½.
What are tachyons and why do we think they exist?
A tachyon (/ ˈ t æ k i ɒ n /) 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. If such particles did exist, and could send signals faster than light, then according to the theory of relativity they would violate causality
Is there any proof that tachyons exist?
If conventional SR is true, then real mass tachyons do not exist. Beyond that, we have no evidence for tachyons of any type. Some researchers think there good reason to consider their existence, others do not. Aug 18, 2018
Is it possible to detect tachyons?
Tachyons would still have mass-energy, so in principle, they could be detected through their gravitational field. Beyond that, they might be detectable if they interacted nongravitationally with other forms of matter. The nature of that interaction depends on the specifics of the theory, so there is no universal answer.
What exactly are tachyons?
Tachyons are particles, whose concepts were first introduced into Physics by the late Gerald Feinberg of Columbia University in his seminar paper, “On the possibility of faster-than-light particles.” (Feinberg, 1967) This helps us get a simple concept about tachyons. They are particles “said” to travel faster than light.
