  2. Quantum mechanics of time travel - Wikipedia

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

    The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.

  3. Tipler cylinder - Wikipedia

    en.wikipedia.org/wiki/Tipler_cylinder

    A Tipler cylinder, also called a Tipler time machine, is a hypothetical object theorized to be a potential mode of time travel—although results have shown that a Tipler cylinder could only allow time travel if its length were infinite or with the existence of negative energy.

    As of 2024, he is a Professor Emeritus of Physics at the University of Connecticut. [7] In 2007, Mallett's life story of pursuing a time machine was told on This American Life, Episode #324, Act 2. [8]

  5. J. Richard Gott - Wikipedia

    Paul Davies, How to build a time machine, 2002, Penguin popular science, ISBN 0-14-100534-3 gives a very brief non-mathematical description of Gott's alternative; the specific setup is not intended by Gott as the best-engineered approach to moving backwards in time, rather, it is a theoretical argument for a non-wormhole means of time travel.

  6. Applied Physics A - Wikipedia

    en.wikipedia.org/wiki/Applied_Physics_A

    Applied Physics A: Materials Science and Processing is a peer-reviewed scientific journal that is published monthly by Springer Science+Business Media. The editor-in-chief is Thomas Lippert (Paul Scherrer Institute). This publication is complemented by Applied Physics B (Lasers & Optics).

  7. Applied Physics Reviews - Wikipedia

    en.wikipedia.org/wiki/Applied_Physics_Reviews

    Applied Physics Reviews is a quarterly peer-reviewed scientific journal publishing original research and reviews of topics of experimental or theoretical research in applied physics and applications of physics to other branches of science and engineering.

  8. Chronology protection conjecture - Wikipedia

    en.wikipedia.org/wiki/Chronology_protection...

    The chronology protection conjecture is a hypothesis first proposed by Stephen Hawking that laws of physics beyond those of standard general relativity prevent time travel—even when the latter theory states that it should be possible (such as in scenarios where faster than light travel is allowed).

  9. Freeman Dyson - Wikipedia
