  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    A type held open by negative mass cosmic strings was put forth by Visser in collaboration with Cramer et al., [42] in which it was proposed that such wormholes could have been naturally created in the early universe. Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as

  3. ER = EPR - Wikipedia

    en.wikipedia.org/wiki/ER_=_EPR

    ER = EPR is a conjecture in physics stating that two entangled particles (a so-called Einstein–Podolsky–Rosen or EPR pair) are connected by a wormhole (or Einstein–Rosen bridge) [1] [2] and is thought by some to be a basis for unifying general relativity and quantum mechanics into a theory of everything. [1]

  4. Quantum foam - Wikipedia

    en.wikipedia.org/wiki/Quantum_foam

    A graphic representation of Wheeler's calculations of what quantum reality may look like at the Planck length. Quantum foam (or spacetime foam, or spacetime bubble) is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics.

  5. Nathan Rosen - Wikipedia

    en.wikipedia.org/wiki/Nathan_Rosen

    Nathan Rosen (Hebrew: נתן רוזן; March 22, 1909 – December 18, 1995) was an American and Israeli physicist noted for his study on the structure of the hydrogen molecule and his collaboration with Albert Einstein and Boris Podolsky on entangled wave functions and the EPR paradox.

  6. Closed timelike curve - Wikipedia

    en.wikipedia.org/wiki/Closed_timelike_curve

    Additionally, every space location has a future time, implying that an object may stay at any location in space indefinitely. Any single point on such a diagram is known as an event . Separate events are considered to be timewise separated if they differ along the time axis, or spacewise separated if they differ along the space axis.

  7. 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.

  8. Non-orientable wormhole - Wikipedia

    en.wikipedia.org/wiki/Non-orientable_wormhole

    The space that this male fiddler crab (a chiral object) lives in, a Möbius strip, is non-orientable. Note that the fiddler crab flips to being its own mirror image with every complete circulation. In wormhole theory, a non-orientable wormhole is a wormhole connection that appears to reverse the chirality of anything passed

    It involves a highly theoretical object called a “ring wormhole,” which is a type of wormhole that connects two regions of space, like a portal. Ring wormholes had previously been theorized to ...
