But we now know that a tachyon indicates an instability in a theory that contains it. Regrettably, for science fiction fans, tachyons are not real physical particles that appear in nature.

Oct 31, 2025 · 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 …

Nov 24, 2021 · The term "tachyon" first entered scientific literature in 1967, in a paper entitled "Possibility of faster-than-light particles" by Columbia University physicist Gerald Feinberg.

Jul 11, 2024 · Once this fact was incorporated into the theory, all the difficulties mentioned earlier completely disappeared and tachyon theory became mathematically consistent.

Tachyon is the name given to the supposed "fast particle" which would move with v > c. Tachyons were first introduced into physics by Gerald Feinberg, in his seminal paper "On the possibility of faster …

Oct 21, 1999 · 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...

Sep 12, 2016 · How particles are detected depends on properties other than their velocity. To answer your question, we have to ask: What kind of particle might be a tachyon?

A tachyon or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists posit that faster-than-light particles cannot exist...

Feb 21, 2023 · An extraordinary particle called the tachyon could travel back in time, scientists say. Here's what we know about it.

The phenomenon of spontaneous symmetry breaking, which is closely related to tachyon condensation, plays a central part in many aspects of theoretical physics, including the Ginzburg–Landau and BCS …
