| has gloss | eng: The Superbradyon is a hypothetical elementary particle that can travel much faster than the speed of light. But unlike tachyons, superbradyons would have positive real values for both mass and energy. Superbradyons would be a new kind of existent particles, really faster than light, able to transmit faster than light information and to violate standard causality. They are not related to any form of instability, as it is the case for tachyons from which they are fundamentally different. |
