The Universe is defined as the summation of all particles and energy that exist and the space-time in which all events occur.
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.

- everything that exists anywhere; "they study the evolution of the universe"; "the biggest tree in existence"
-population: (statistics) the entire aggregation of items from which samples can be drawn; "it is an estimate of the mean of the population"
-everything stated or assumed in a given discussion

The universe includes everything we know and everything we don't.

All matter and energy, including the earth, the galaxies, and the contents of intergalactic space, regarded as a whole.
