"Tachyon" Natural Recordings by Native Speakers
A tachyon is a hypothetical particle or a disturbance that travels faster than the speed of light. The term was coined by physicist Gerald Feinberg in 1967.
According to theory, if tachyons exist, they would have imaginary mass and negative rest energy. However, there is currently no scientific evidence to support their existence. Tachyons are often used in science fiction to create plot devices and mechanisms, often violating the laws of physics and the speed of light limit, which remains an unbreachable barrier in our current understanding of the universe.
