A tachyon is a particle that is moving faster than the speed of light. Tachyons are currently only theoretical, and many scientists believe that they could not exist based on our understanding of the physics in this universe. Tachyons were first proposed by Gerald Feinberg in a paper he wrote in 1967 which coined the term tachyon and outlined a baseline for some of the theoretical physics surrounding them.
The Main Idea
Tachyons always move faster than the speed of light, while its complements, luxons, always move at the speed of light (ex. photon), and bradyons, which always are moving slower than light. Both of these complements exist, while tachyons are still only hypothetical. Most physicists believe that tachyons could not exist because their existence would break the barrier of the speed of light and therefor disrupt causality. For example, if tachyons did exist, Einstein postulated that it would be possible to build a device known as a tachyonic antitelephone, which would allow the transmission of messages faster than the speed of light, and therefor into the past. This would allow someone to answer a question before it was even asked, breaking the relationship of cause and effect we know as causality.
