this ring seems to allow a closed time loop with stable wormholes when analyzed using semiclassical gravity, although without a full theory of quantum gravity it is uncertain whether the semiclassical approach is reliable in this case.

== traversable wormholes ==lorentzian traversable wormholes would allow travel from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another.
== traversable wormholes ==lorentzian traversable wormholes would allow travel in both directions from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another.
===atmospheric diving suits===the atmospheric diving suit is a small one-man submersible of anthropomorphic form with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere.

an example of a (traversable) wormhole metric is the following::formula_1one type of non-traversable wormhole metric is the schwarzschild solution (see the first diagram)::formula_2== in fiction ==wormholes are a common element in science fiction as they allow interstellar (and sometimes interuniversal) travel within human timescales.
