tachyon particle?

Question

Can tachyons travel greater than the speed of light? or just at the speed light.

Answer 1

Tachyons are theoretical and come about as a necessary hypothesis for quantum weirdness. Another way to look at the quantum world is to look at time zero. At time zero, the arrow of time moved every which way in the quantum foam that was about to unfurl into four dimensions (11 dimensions if you count superstring theory). Those initial underpinnings of our universe still manifest today. In theory, for example, a pair of virtual particles can be separated by light years, but if you change the "spin" of one way over there light years away, the other will know it instantly. The theory of non-locality is fascinating, and it dovetails with such things as beam-splitter experiments, where an electron, the same electron, will be in two places at the same time.

Tachyon
From Wikipedia, the free encyclopedia
Jump to: navigation, search
A tachyon (from the Greek ταχύς,ταχυόνια (takhús), meaning "swift, fast") is any hypothetical particle that travels at superluminal velocity. The first description of tachyons is attributed to German physicist Arnold Sommerfeld, but it was George Sudarshan, Olexa-Myron Bilaniuk[1][2] and Gerald Feinberg[3] (who originally coined the term) in the 1960s who advanced a theoretical framework for their study. Tachyonic fields have appeared theoretically in a variety of contexts, such as the Bosonic string theory. In the language of special relativity, a tachyon is a particle with space-like four-momentum and imaginary proper time. A tachyon is constrained to the space-like portion of the energy-momentum graph. Therefore, it can never slow to light speed or below. Today, in the framework of quantum field theory, tachyons are often understood to signify an instability of the system, although even if they were conventional, localisable particles they would still preserve the basic tenets of causality in special relativity and not allow information to move faster than light.[3]

Hi. Tachyons can ONLY travel faster than light. http://www.answers.com/main/ntquery?s=tachyon&gwp=13
