  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    To see why exotic matter is required, consider an incoming light front traveling along geodesics, which then crosses the wormhole and re-expands on the other side. The expansion goes from negative to positive. As the wormhole neck is of finite size, we would not expect caustics to develop, at least within the vicinity of the neck.

    In general relativity, a Roman ring (proposed by Matt Visser in 1997 [1] and named after the Roman arch, a concept proposed by Mike Morris and Kip Thorne in 1988 and named after physicist Tom Roman) [2] is a configuration of wormholes where no subset of wormholes is near to chronology violation, though the combined system can be arbitrarily close to chronology violation.

  8. Spaghettification - Wikipedia

    en.wikipedia.org/wiki/Spaghettification

    In the most extreme cases, near a black hole, the stretching and compression are so powerful that no object can resist it. Within a small region, the horizontal compression balances the vertical stretching so that a small object being spaghettified experiences no net change in volume.

  9. Ellis wormhole - Wikipedia

    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.
