What if tachyons exist?

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.

Why can’t tachyons exist?

A tachyon (/ˈtækiɒn/) 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. No experimental evidence for the existence of such particles has been found.

What is the speed of darkness?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light.

Can tachyons 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.

Are tachyons real?

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.

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.

What is the simplest explanation for tachyon field?

What is a tachyonic field? A tachyon or tachyonic particle is a hypothetical massive particle that always moves faster than light. The complementary particle types are called luxon (always moving…

What are tachyon particles?
