  2. Faster-than-light - Wikipedia

    en.wikipedia.org/wiki/Faster-than-light

    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.

  3. Alcubierre drive - Wikipedia

    en.wikipedia.org/wiki/Alcubierre_drive

    The Star Trek television series and films use the term "warp drive" to describe their method of faster-than-light travel. Neither the Alcubierre theory, nor anything similar, existed when the series was conceived—the term "warp drive" and general concept originated with John W. Campbell's 1931 science fiction novel Islands of Space. [47]

  4. Tachyon - Wikipedia

    en.wikipedia.org/wiki/Tachyon

    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. [19] [20] [21] In this framework, neutrinos experience Lorentz-violating oscillations and can travel faster than light at high energies. This proposal was strongly ...

  5. Miguel Alcubierre - Wikipedia

    en.wikipedia.org/wiki/Miguel_Alcubierre

    In this, he describes the Alcubierre drive, a theoretical means of traveling faster than light that does not violate the physical principle that nothing can locally travel faster than light. In this paper, he constructed a model that might transport a volume of flat space inside a "bubble" of curved space.

  6. Warp drive - Wikipedia

    en.wikipedia.org/wiki/Warp_drive

    Einstein's theory of special relativity states that speed of light travel is impossible for material objects that, unlike photons, have a non-zero rest mass. The problem of a material object exceeding light speed is that an infinite amount of kinetic energy would be required to travel at exactly the speed of light.

  7. Superluminal communication - Wikipedia

    en.wikipedia.org/wiki/Superluminal_communication

    The current scientific consensus is that faster-than-light communication is not possible, and to date it has not been achieved in any experiment. Superluminal communication other than possibly through wormholes is likely impossible [1] because, in a Lorentz-invariant theory, it could be used to transmit information into the past.

  8. Intergalactic travel - Wikipedia

    en.wikipedia.org/wiki/Intergalactic_travel

    The Alcubierre drive is a hypothetical concept that is able to propel a spacecraft to speeds faster than light (the spaceship itself would not move faster than light, but the space around it would). This could in theory allow practical intergalactic travel.

  9. Lighthouse paradox - Wikipedia

    en.wikipedia.org/wiki/Lighthouse_paradox

    The theory of relativity says information cannot be transmitted faster than light. This experiment does not actually transmit a signal from object 1 to object 2. The time when the light beam strikes object 2 is controlled by the person at the lighthouse, not anyone on object 1, so no one on object 1 can transmit a message to object 2 by this ...
