What is the theory of tachyons?
A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light. 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 they could be used to send signals faster than light.
What is the formula of tachyon?
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.
Can you capture a tachyon?
Adding energy to a tachyon can be shown to slow it down, but an infinite amount of energy would be required to slow it to the speed of light. To observe them does not require light to ‘catch’ them, but only to interact – the light could be coming from any direction.
Can a tachyon go back in time?
One of the fundamental postulates of special relativity is that the laws of physics should be the same in all non-accelerating reference frames. That means if tachyons can violate causality and move backward in time in one reference frame, it can do it in them all.
Can tachyon escape black hole?
Since the disturbance of a localized tachyon cannot spread faster than c, it therefore cannot escape the inside of a black hole’s event horizon.
Why do tachyons travel back in time?
The tachyon is created on the “now” hypersurface of simultaneity and propagates towards the “earlier” hypersurface of simultaneity. It arrives at the earlier hypersurface that collects events from an earlier time before it was created. That means that the tachyon is traveling backwards in time.

Are tachyons dark matter?
Though considering tachyons as some component of dark matter doesn’t change the cosmological consequences but they would indeed have some effect on the nucleosynthesis.
