1 a If such particles did exist they could be used to send signals faster than light. Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics. Imaginary mass fields fields have come to play an important role in modern physics. A tachyon ( / tkin /) or tachyonic particle is a hypothetical particle that always travels faster than light. The idea of those mass fields, comes in part from Quantum field theory, and Classical field theory. In modern physics the term 'tachyon' often refers to imaginary mass fields rather than to faster-than-light particles. In September 2011, it was reported that a tau neutrino had traveled faster than the speed of light in a major release by CERN however, later updates from CERN on the OPERA project indicate that the faster-than-light readings were resultant from 'a faulty element of the experiment's fibre optic timing system'. Lately, Similar concept was coined with the term 'tachyon' by Gerald Feinberg in 1967. After that the possibility of particles moving faster than light was also proposed by Robert Ehrlich and Arnold Sommerfeld, independently of each other. Sudarshan, V.K Deshpande and Baidyanath Misra were the first to propose the existence of particles faster than light and named them 'meta-particles'. If a tachyon did exist, it would have an imaginary number as its mass.Į. In Einstein’s theory of special relativity, only massless particles like the photon travel at the speed. Advertisements Can Tachyons escape a black hole Yes. Tachyons are hypothetical particles that travel faster than the speed of light in a vacuum. Because if any particle can do so then it will not be consistent with the laws of physics. For most physicists, it is practically impossible to travel faster than light. Most physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics. A Tachyon particle is a hypothetical particle that always travels faster than light. Einstein's theory of special relativity states that nothing can accelerate faster than the speed of light, while tachyons are theorized to be constantly traveling faster than the speed of light. A tachyon (/tkin/) or tachyonic particle is a hypothetical particle that always travels faster than light. Most scientists do not believe that tachyons exist. A tachyon is any hypothetical particle that can travel faster than the speed of light. Tachyons: The Hypothetical Faster-Than-Light Particles in Physics The story behind and the connection to the Higgs field, time travel, and dark energy T he Higgs field was a tachyonic field before.
