HOLA MATE HERE IS UR ANSWER ♥♥♥♥
tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always moves faster than light. Most physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics.[1][2] If such particles did exist, they could be used to build a tachyonic antitelephone and send signals faster than light, which (according to special relativity) would lead to violations of causality.[2] No experimental evidence for the existence of such particles has been found.
The possibility of particles moving faster than light was first proposed by O. M. P. Bilaniuk, V. K. Deshpande, and E. C. G. Sudarshan in 1962, although the term they used for it was "meta-particle".[3] In the 1967 paper that coined the term,[4] Gerald Feinberg proposed that tachyonic particles could be quanta of a quantum field with imaginary mass. However, it was soon realized that excitations of such imaginary mass fields do not under any circumstances propagate faster than light,[5]and instead the imaginary mass gives rise to an instability known as tachyon condensation.[1] Nevertheless, in modern physics the term "tachyon" often[1][6] refers to imaginary mass fields rather than to faster-than-light particles. Such fields have come to play a significant role in modern physics.
The term comes from the Greek: ταχύ, tachy, meaning "rapid". The complementary particle types are called luxons (which always move at the speed of light) and bradyons (which always move slower than light); both of these particle types are known to exist.
In general, tachyons are a standby mechanism upon which many science fictionauthors rely to establish faster-than-light communication, with or without reference to causality issues. For example, in the Babylon 5television series, tachyons are used for real-time communication over long distances. Another instance is Gregory Benford's novel Timescape, winner of the Nebula Award, which involves the use of tachyons to transmit a message of salvation back in time. Likewise, John Carpenter's horror film Prince of Darkness uses tachyons to explain how future humans send messages backward through time to warn the characters of their impending doom. By contrast, Alan Moore's classic comic book limited series Watchmenfeatures a character who uses "a squall of tachyons" broadcasting from space to muddle the mind of the only person on Earth capable of seeing the future.
The word "tachyon" has become widely recognized to such an extent that it can impart a science-fictional "sound" even if the subject in question has no particular relation to superluminal travel (compare positronic brain). Classic Anime fans may associate tachyons with the energy source for the wave-motion gun and wave-motion engine in Space Battleship Yamato (Starblazers in the United States). Further examples include the "Tachion Tanks" of the PC game Dark Reignand the "tachyon beam" of the game Master of Orion. The space-combat sim Tachyon: The Fringe utilizes "tachyon gates" for superluminal travel but gives no exact explanation for the technology, and the MMORPG Eve Online features six types of "Large Tachyon Lasers", technically a contradiction since by definition, lasers emit light—photons, not any kind of hypothetical tachyon.
