In physics, a tachyonic field, or simply tachyon, is a quantum field with an imaginary mass. [1] Although tachyonic particles ( particles that move faster than light) are a purely hypothetical concept that violate a number of essential physical principles, at least one field with imaginary mass, the Higgs field, is believed to exist.
WebOct 7, 2024 · 4.1.4 Tachyons If , that is, the particle is moving faster than the speed of light, then the norm of the 4-velocity (165) will necessarily be and thus the path must be spacelike.

WebFrom quantum field theory we know that any particle with a mass that is not purely real must be unstable and in fact tachyons are maximally unstable - they are guaranteed to decay into no-tachyonic particles through a process called tachyon condensation. WebNov 24, 2024 · Tachyons are one of the most interesting elements arising from Einstein’s theory of special relativity. The 1905 theory is based on two postulates, nothing with mass …
A tachyon or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics. If such particles did exist they could be used to send signals faster than light. According to the … See more The term tachyon was coined by Gerald Feinberg in a 1967 paper titled "Possibility of faster-than-light particles". He had been inspired by the science-fiction story "Beep" by James Blish.
