Tachyon/Talk

A tachyon could be a magnetic monopole. Many theoretical searches for magnetic monopoles have concluded they may not exist thanks to them breaking multiple physical laws (conservation of energy for one). It seems fashionable to attribute to tachyons anything proven to be impossible.

Can anyone verify this? I removed it as it sounds highly dubious to me; in any case, it is too vague.

We might also need discussion about the wave front effect, virtual particles, and how exactly causality is violated if tachyons exist (which might as well go into the causality link.)
