entity, physical body, and abstract objectis part of everything. Everything is the opposite of nothing, though an alternative view considers "nothing" a part of everything.
The "World" is a noun for the planet
Earthenvisioned from an anthropocentricor human worldview, as a place inhabited by human beings. It is often used to signify the sum of human experienceand history, or the ' human condition' in general. ['This is the excellent foppery of the world...' -- Shakespeare, " King Lear", I.ii]
Especially in a metaphysical context, "World" may refer to everything that constitutes
realityand the Universe: see World (philosophy).
The "Universe" is most commonly defined as everything that physically exists: the entirety of
spaceand time, all forms of matter, energyand 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".
Experiments suggest that the universe has been governed by the same physical laws and constants throughout its extent and history. The dominant force at cosmological distances is
gravity, and general relativityis currently the most accurate theory of gravitation. The remaining three fundamental forces and the particles on which they act are described by the Standard Model. The universe has at least three dimensions of space and one of time, although extremely small additional dimensions cannot be ruled out experimentally. Spacetimeappears to be a simply connectedsmooth manifold, and space has very small mean curvature, so that Euclidean geometryis accurate "on the average" throughout the universe.
According to some speculations, this universe may be one of many disconnected universes, which are collectively denoted as the
multiverse. In one theory, there is an infinite variety of universes, each with different physical constants. In another theory, new universes are spawned with every quantum measurement. By definition, these speculations cannot currently be tested experimentally.
In theoretical physics
theoretical physics, a "theory of everything" (TOE) is a hypothetical theorythat fully explains and links together all known physical phenomena. Initially, the term was used with an ironic connotation to refer to various overgeneralized theories. For example, a great-grandfather of Ijon Tichy— a character from a cycle of Stanisław Lem's science fictionstories of 1960s — was known to work on the "General Theory of Everything". Over time, the term stuck in popularizations of quantum physicsto describe a theory that would unify or explain through a single model the theories of all fundamental interactions of nature.
There have been many theories of everything proposed by theoretical physicists over the last century, but none have been confirmed experimentally. The primary problem in producing a TOE is that the accepted theories of
quantum mechanicsand general relativityare hard to combine.
Based on theoretical
holographic principlearguments from the 1990s, many physicists believe that 11-dimensional M-theory, which is described in many sectors by matrix string theory, in many other sectors by perturbative string theory is the complete theory of everything. Other physicists disagree.
In philosophy, a theory of everything or TOE is an ultimate, all-encompassing explanation of
natureor reality.Rescher, Nicholas (2006a). "Holistic Explanation and the Idea of a Grand Unified Theory". Collected Papers IX: Studies in Metaphilosophy. ] Rescher, Nicholas (2006b). "The Price of an Ultimate Theory". Collected Papers IX: Studies in Metaphilosophy. ] Walker, Mark Alan (March 2002). [http://www.jetpress.org/volume10/prolegomena.html "Prolegomena to Any Future Philosophy"] . Journal of Evolution and Technology Vol. 10. ] Adopting the term from physics, where the search for a theory of everythingis ongoing, philosophers have discussed the viability of the concept and analyzed its properties and implications. Among the questions to be addressed by a philosophical theory of everything are: "Why is reality understandable?" "Why are the laws of nature as they are?" "Why is there anything at all?"
