Tachyons are hy­po­thet­i­cal sub-atomic par­ti­cles that al­ways move faster than light. These were hy­poth­e­sised by Arnold Sommerfeld and ad­vanced by other sci­en­tists. Tachyons have al­ways held the fancy of sci­en­tists and sci­ence fic­tion au­thors. How­ever, till date the con­cept has been con­sid­ered only as the­ory and sci­en­tists have held that tachyon par­ti­cles are too un­sta­ble to be treated as ex­is­tent. Sci­en­tists have also held that faster-than-light in­for­ma­tion trans­mis­sion and causal­ity vi­bra­tion with tachyons are im­pos­si­ble.

Ac­cord­ing to Ger­ald Fein­berg, one of the pro­po­nents of tachyon the­o­ries, even if these are con­ven­tional lo­calised par­ti­cles they would still pre­serve the ba­sic tenets of causal­ity in spe­cial rel­a­tiv­ity and not al­low trans­mis­sion of in­for­ma­tion faster than light. So we are yet to see whether the neu­tri­nos ob­served by OPERA are to be con­sid­ered as tachyons, and whether they will con­tinue to stick to the the­o­ries of spe­cial rel­a­tiv­ity or un­veil new truths hith­erto un­known!
