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.

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.

Dec 26, 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 …

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

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 …

Sep 14, 2025 · In theory, a tachyon could be used to send messages faster than light speed and this has the effect that some observers in space-time would receive the message before it was …

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 …

Explore Tachyon Physics Physics & Mathematics Understand the mathematical framework behind tachyons and their relationship to Einstein's relativity.

The word tachyon derives from the Greek (tachus), meaning "speedy." Tachyons have the strange properties that, when they lose energy, they gain speed. Consequently, when …

Oct 6, 2023 · In 1967, Gerald Feinberg coined the name tachyon. Putting a name to it led some non-physicists to assume tachyons had been found, or at least evidence for their existence …
