  2. Quantum mechanics of time travel - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics_of_time...

    Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), theoretical loops in spacetime that might make it possible to travel through time. [1][2][3][4] In the 1980s, Igor Novikov proposed the self-consistency principle. [5] According to this principle, any changes made by ...

    en.wikipedia.org/wiki/Novikov_self-consistency...

    The Novikov self-consistency principle, also known as the Novikov self-consistency conjecture and Larry Niven 's law of conservation of history, is a principle developed by Russian physicist Igor Dmitriyevich Novikov in the mid-1980s. Novikov intended it to solve the problem of paradoxes in time travel, which is theoretically permitted in ...

  5. Time travel - Wikipedia

    en.wikipedia.org/wiki/Time_travel

    The first page of The Time Machine published by Heinemann. Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine.

  6. Modern physics - Wikipedia

    en.wikipedia.org/wiki/Modern_physics

    v. t. e. Modern physics is a branch of physics that developed in the early 20th century and onward or branches greatly influenced by early 20th century physics. Notable branches of modern physics include quantum mechanics, special relativity, and general relativity. Classical physics is typically concerned with everyday conditions: speeds are ...

  7. History of quantum mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_quantum_mechanics

    The history of quantum mechanics is a fundamental part of the history of modern physics. The major chapters of this history begin with the emergence of quantum ideas to explain individual phenomena—blackbody radiation, the photoelectric effect, solar emission spectra—an era called the Old or Older quantum theories. [1]

  8. Temporal paradox - Wikipedia

    en.wikipedia.org/wiki/Temporal_paradox

    Temporal paradox. A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time travel or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic time ...

  9. 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 (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.
