Everything


Everything (or every thing), is all that exists; the opposite of nothing, or its complement. It is the totality of things relevant to some subject matter . Without expressed or implied limits, it may refer to anything. The Universe is everything that exists theoretically, though a multiverse may exist according to theoretical cosmology predictions. It may refer to an anthropocentric worldview, or the sum of human experience, history, and the human condition in general. Every object and entity is a part of everything, including all physical bodies and in some cases all abstract objects.

In ordinary conversation, everything usually refers only to the totality of things relevant to the subject matter. When there is no expressed limitation, everything may refer to the universe, the world.

The Universe is most commonly defined as everything that physically exists: the entirety of time, all forms of matter, energy and momentum, and the physical laws and constants that govern them. However, the term "universe" may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world or Nature. According to some speculations, this universe may be one of many disconnected universes, which are collectively denoted as the multiverse. In the bubble universe theory, there is an infinite variety of universes, each with different physical constants. In the many-worlds hypothesis, new universes are spawned with every quantum measurement. By definition, these speculations cannot currently be tested experimentally, yet, if they exist, they would still be part of everything.
