Can Tachyons go 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.

How is tachyon detected?

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.

What if tachyons were real?

In Einstein’s theory of special relativity, only massless particles like the photon travel at the speed of light; all other particles travel slower. The existence of tachyons can lead to “time travel” paradoxes. If tachyons were electrically charged, they could produce Cherenkov radiation in empty space.

Where does tachyon exist?

Just as an ordinary particle such as an electron can exist only at speeds less than that of light, so a tachyon could exist only at speeds above that of light, at which point its mass would be real and positive. Upon losing energy, a tachyon would accelerate; the faster it traveled, the less energy it would have.

Are Tachyons dark matter?

So we may conclude that tachyons will constitute a negligible fraction of the dark matter at this epoch, unless either (i) N is much larger than for tardyons or, (ii) n is determined not by a condition of early thermodynamic equilibrium, but by some other criterion.

Does tachyon 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.

What would happen if tachyons were real?

Are tachyons theoretical?

“Briefly, tachyons are theoretically postulated particles that travel faster than light and have ‘imaginary’ masses.

Where does Tachyon exist?

What is a tachyon in physics?

Tachyon is just a general term for some hypothetical particle that travels faster than the speed of light. According to the theory of special relativity that particle must have an imaginary mass.

Is it possible to detect a tachyon?

And because the existence of a tachyon is inconsistent with Einstein’s remarkably successful theory, a claim of tachyon detection would require extraordinary evidence. How particles are detected depends on properties other than their velocity.

Can a tachyon travel faster than light?

Tachyons are realized in quantum field theory as particles with negative squared mass. As such, the mass would be imaginary. Taken at face value, this would indicate that the particle would travel faster than light because of the relation ship this would seem to indicate a particle traveling faster than light.

Are tachyons real or imaginary?

Tachyons are as real as they are imaginary. They are one if those things in physics which are mathematical possibility, but we don’t have the technology to check out if they are a physical reality or not. Tachyons are particles, which travel faster than light.
