Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons ) may travel at the speed of light, and that nothing may travel faster.
The possibility of standard model particles moving at faster-than-light speeds can be modeled using Lorentz invariance violating terms, for example in the Standard-Model Extension. [18] [19] [20] In this framework, neutrinos experience Lorentz-violating oscillations and can travel faster than light at high energies. This proposal was strongly ...
This thought experiment proposes that light moving in this situation is actually traveling faster than the speed of light. This presents a paradox because, according to the theory of relativity, the speed of light in vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source, and nothing can ...
The Alcubierre drive ([alkuˈβjere]) is a speculative warp drive idea according to which a spacecraft could achieve apparent faster-than-light travel by contracting space in front of it and expanding space behind it, under the assumption that a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.
However, in 1905 Poincaré calculated that changes in the gravitational field can propagate with the speed of light if it is presupposed that such a theory is based on the Lorentz transformation. He wrote: [16] Laplace showed in effect that the propagation is either instantaneous or much faster than that of light.
Radiation with the same properties of typical Cherenkov radiation can be created by structures of electric current that travel faster than light. [ 20 ] By manipulating density profiles in plasma acceleration setups, structures up to nanocoulombs of charge are created and may travel faster than the speed of light and emit optical shocks at the ...
Commercial flights typically travel between 480 to 575 mph speeds, according to Flex Air Flight School. Eddie Sheerr, a meteorologist with NTV News in Canada, said in a post on X that the planes ...
Wormhole travel as envisioned by Les Bossinas for NASA, c. 1998. The impossibility of faster-than-light relative speed applies only locally. Wormholes might allow effective superluminal (faster-than-light) travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, subluminal (slower-than ...
