  • n. Plural form of tachyon.


Sorry, no etymologies found.


  • Scalar waves • Propagate faster than Light speed (hence the name tachyons), except when transmitting scalar information on electromagnetic carrier waves. • effect is independent of distance and time. • effect is 3-5 times stronger than that of electromagnetic fields. • more fundamental than magnetic fields. • transmit information, not energy.

  • In the 1960s and 1970s, physicists began to discuss the possibilities of particles travelling with a speed greater than light, the so-called tachyons, and as a consequence a similar debate about paradoxes involving backward causation arose among them.

    Backward Causation

  • The theory also predicted the existence of certain particles called tachyons whose mass was not a real number, and which traveled faster than light.

    Euclid’s Window

  • Technically, relativity does allow some particles, known as tachyons, to go faster than light - in fact it forbids them to slow down to light speed.

  • For particular stories, I've done targeted research: nanotechnology, cosmic strings, and supernovas for From a Changeling Star; chaos theory and the Voyager spacecraft findings about Neptune and Triton for Neptune Crossing; tachyons for The Infinity Link; stellar nurseries and stellar evolution for Sunborn.

  • The only no-kidding science fiction time travel story that ranks highly with me is a novel, Gregory Benford's Timescape, an intense lab-procedural about escaping the inescapable, involving more tachyons than an entire season of Dr Who, but I never for a moment read it as fantasy, in fact, it's remained one of my all-time greats.

  • But there are plenty of other good possibilities; what if we discovered tachyons, or that there really was an Intelligent Designer?

  • If something prevents the existence of tachyons I bet it would be causality, not thermodynamics.
