Have tachyons actually been shown to exist? I was under the impression that they are theoretical, a prediction of some theories but not verified.

- kowdermeister 12y agoNot yet, so far they are theoretical, but this is what the paper is about.
- gliese1337 12y agoThis paper is claiming that they have. If neutrinos move faster than light, then by definition they are tachyons. Nobody has come out and said "we have verified the existence of tachyons, and neutrinos might be some of them". Rather, the claim that neutrinos move faster than light is the claim of verifying tachyons. Incidentally, in this case the claim seems a bit more roundabout: that neutrinos may have imaginary mass, a different but equally-well-defining feature of tachyons, and thus they can move faster than light.
