In order to clarify terminology, [[George Ellis]], U. Kirchner and W.R. Stoeger recommend using the term ''the Universe'' for the theoretical model of all of the connected space-time in which we live, ''universe domain'' for the observable universe or a similar part of the same space-time, ''universe'' for a general space-time (either our own ''Universe'' or another one disconnected from our own), ''multiverse'' for a [[set]] of disconnected space-times, and ''multi-domain universe'' to refer to a model of the whole of a single connected space-time in the sense of [[chaotic inflation]] models. | In order to clarify terminology, [[George Ellis]], U.
