They concluded that superluminal particles such as tachyons are therefore not allowed to convey signals. The hypothetical elementary particles with this property are called tachyons or tachyonic particles. Tachyons are unusual because the instability prevents any such localized excitations from existing. In string theory, tachyons have the same interpretation as in quantum field theory. The hypothetical particles tachyons have inspired many occurrences of in fiction. Standard vectors on the one-sheeted hyperbolas would correspond to tachyons. The problem of detecting tachyons via causal contradictions was treated but without scientific verification. His description of rolling tachyons has been influential in string cosmology. In some modern formulations of the theory, the mass of tachyons is regarded as real. There is no confirmed existence of tachyons. "Happy Tachyons" and the double concerto for piano and percussion "View From Olympus". It was filled with energized tachyons, time in its most basic form. In this context, they are sometimes called "luxons" to distinguish them from bradyons and tachyons. Tachyons have appeared in many works of fiction. Tachyons therefore became an active area of interest in the early 2000s.
