Roman ring

This article is about the physics concept. For the gymnastics apparatus, see Rings (gymnastics).

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.
