A spaceship traveling at speed less than c from Earth to the galaxy could conceivably find that the tachyon arrived at the galaxy before it left Earth! It has been proposed that tachyons might be created in high-energy particle collisions or in cosmic rays. Consider a tachyon leaving Earth at time t=0 that arrives at a distant galaxy at time T. If the tachyon’s energy is reduced, it speeds up! Because tachyons travel faster than c, we have a problem with causality. Note that the energy must become infinite if we want to slow down a tachyon to speed c. Faster-than-light neutrino result reportedly a mistake caused by loose cable UPDATED Sources at CERN have told ScienceInsider that a hardware problem with an John Timmer - 7. Just getting close to it causes problems: the weird distortions of. In order to slow down a tachyon, we must give it more energy, according to the previous Equation. The speed of light in a vacuum is the ultimate cosmic speed limit.
Remember that ordinary matter must always travel at speed less than c, light must travel at the speed of light, and tachyons must always have speed greater than c. Let’s first examine the following Equation for energy: E= gamma * mc 2 = mc 2 /(sqrt(1-u 2 / c 2 ))īecause u > c, the energy must be imaginary if the mass is real, or conversely, if we insist that energy be real, we must have an imaginary mass! For purposes of discussion, we will henceforth assume that energy is real and tachyon mass is imaginary. (The word tachyon is derived from the Greek word tachus, which means “speedy.”) Tachyons are postulated particles that travel faster than the speed of light.
