  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    For a simplified notion of a wormhole, space can be visualized as a two-dimensional surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance. An actual wormhole would be analogous to ...

  3. 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

  4. Intergalactic travel - Wikipedia

    en.wikipedia.org/wiki/Intergalactic_travel

    There is no known way to create the space-distorting wave this concept needs to work, but the metrics of the equations comply with relativity and the limit of light speed. [ 9 ] A wormhole is a hypothetical tunnel through space-time that would allow instantaneous intergalactic travel to the most distant galaxies even billions of light years away.

  5. Penrose diagram - Wikipedia

    en.wikipedia.org/wiki/Penrose_diagram

    While the basic space-like passage of a static black hole cannot be traversed, the Penrose diagrams for solutions representing rotating and/or electrically charged black holes illustrate these solutions' inner event horizons (lying in the future) and vertically oriented singularities, which open up what is known as a time-like "wormhole ...

  6. Negative energy - Wikipedia

    en.wikipedia.org/wiki/Negative_energy

    Negative energy appears in the speculative theory of wormholes, where it is needed to keep the wormhole open. A wormhole directly connects two locations which may be separated arbitrarily far apart in both space and time, and in principle allows near-instantaneous travel between them.

  7. Faster-than-light - Wikipedia

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

    Speculative faster-than-light concepts include the Alcubierre drive, Krasnikov tubes, traversable wormholes, and quantum tunneling. [1] [2] Some of these proposals find loopholes around general relativity, such as by expanding or contracting space to make the object appear to be travelling greater than c.

    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 ...

  9. Ellis wormhole - Wikipedia

    en.wikipedia.org/wiki/Ellis_wormhole

    The wormhole metric has the proper-time form =, where = + = + (+) = + (+) [+ (⁡)] and is the drainhole parameter that survives after the parameter of the Ellis drainhole solution is set to 0 to stop the ether flow and thereby eliminate gravity.
