Ergodic hypothesis The ergodic hypothesis is often assumed in the statistical analysis of computational physics. The analyst would assume that the average of a process parameter over time and the average over the statistical ensemble are the same. This assumption that it is as good to simulate a system over a long time as it is to make many independent realizations of the same system is not always correct. (See, for example, the Fermi–Pasta–Ulam experiment of 1953.) Phenomenology[edit] In macroscopic systems, the timescales over which a system can truly explore the entirety of its own phase space can be sufficiently large that the thermodynamic equilibrium state exhibits some form of ergodicity breaking. However, complex disordered systems such as a spin glass show an even more complicated form of ergodicity breaking where the properties of the thermodynamic equilibrium state seen in practice are much more difficult to predict purely by symmetry arguments.

Parallel Universes: Theories & Evidence Parallel universes are no longer just a feature of a good sci-fi story. There are now some scientific theories that support the idea of parallel universes beyond our own. However, the multiverse theory remains one of the most controversial theories in science. Our universe is unimaginably big. But is it all that's out there? Multiverses and parallel worlds are often argued in the context of other major scientific concepts like the Big Bang, string theory and quantum mechanics. Related: How big is the universe? Eternal inflation, the Big Bang theory and parallel universes Around 13.7 billion years ago, everything we know of was an infinitesimal singularity. Related: How an inflating universe could create a multiverse That mysterious process of inflation and the Big Bang have convinced some researchers that multiple universes are possible, or even very likely. Those bubble universes can't contact each other because they continue to expand indefinitely. Quantum mechanics and parallel universes
DC Multiverse (Concept) Origin Inside the DC Comics mythology, the sci-fi concept of alternate realities existing as parallel earths has been one of the main characteristics of their superhero universe since the silver age. With an infinite number of similar looking universes than resemble the main universe, the idea of Multiverse is a foundation concept not only in DC Comics but for the whole superhero genre. Creation DC Multiverse was created by Gardner Fox and Carmine Infantino. Universe Evolution Pre-Crisis / The Multiverse (1961-1986) Before the Crisis on Infinite Earths, there were many (hence "infinite") versions of the Earth scattered throughout the Multiverse. This world came to be known as Earth-Two and was populated by the heroes of the "Golden Age" of comics (the 40's and 50's). Post-Crisis / DC Universe (1986-2006) Infinite Crisis / The Multiverse (2006) Post-52 Weeks / The Multiverse (2007-2011 ) Born after 52 (the weekly) and modified by Mr Mind, this multiverse resemble previous incarnations.

aM laboratory 32728-parallel-universes Is our universe unique? From science fiction to science fact, there is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. The concept is known as a "parallel universe," and is a facet of the astronomical theory of the multiverse. The idea is pervasive in comic books, video games, television and movies. There actually is quite a bit of evidence out there for a multiverse. Around 13.7 billion years ago, simply speaking, everything we know of in the cosmos was an infinitesimal singularity. One big question with this theory is: are we the only universe out there? There are at least five theories why a multiverse is possible, as a 2012 Space.com article explained: 1. 2. 3. 4. 5. Famously, physicist's Stephen Hawking's last paper before his death also dealt with the multiverse. Not everyone agrees with the parallel universe theory, however.
Metaverse The Metaverse is a collective virtual shared space, created by the convergence of virtually enhanced physical reality and physically persistent virtual space,[1] including the sum of all virtual worlds, augmented reality, and the internet. The word metaverse is a portmanteau of the prefix "meta" (meaning "beyond") and "universe" and is typically used to describe the concept of a future iteration of the internet, made up of persistent, shared, 3D virtual spaces linked into a perceived virtual universe.[2] Developing technical standards for the Metaverse[edit] Conceptually, the Metaverse describes a future internet of persistent, shared, 3D virtual spaces linked into a perceived virtual universe,[2] but common standards, interfaces, and communication protocols between and among virtual environment systems are still in development. Many of these working groups are still in the process of publishing drafts and determining open standards for interoperability. [edit] [edit] See also[edit]
Aether theories Historical models[edit] Luminiferous aether[edit] Isaac Newton suggests the existence of an aether in the Third Book of Opticks (1718): "Doth not this aethereal medium in passing out of water, glass, crystal, and other compact and dense bodies in empty spaces, grow denser and denser by degrees, and by that means refract the rays of light not in a point, but by bending them gradually in curve lines? ...Is not this medium much rarer within the dense bodies of the Sun, stars, planets and comets, than in the empty celestial space between them? And in passing from them to great distances, doth it not grow denser and denser perpetually, and thereby cause the gravity of those great bodies towards one another, and of their parts towards the bodies; every body endeavouring to go from the denser parts of the medium towards the rarer?" In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light (electromagnetic radiation).

History "This is our earth. —Martin Stein explaining the multiverse[src] Attempting to increase his speed, Barry Allen used a tachyon device, which in turn caused him to run too fast and accidentally create a breach between Earth One and Earth Thirty-Eight, the parallel world that is the home of Supergirl.[7] During his travels, Zolomon discovered that Earth One happened to be in the center juncture of the entire multiverse, and that from there one could travel to any of the other infinite number of Earths.

Membrane (M-theory) In string theory and related theories, D-branes are an important class of branes that arise when one considers open strings. As an open string propagates through spacetime, its endpoints are required to lie on a D-brane. The letter "D" in D-brane refers to the fact that we impose a certain mathematical condition on the system known as the Dirichlet boundary condition. See also[edit] References[edit] Jump up ^ Moore, Gregory (2005). Laplace operator Differential operator In mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a scalar function on Euclidean space. It is usually denoted by the symbols (where is the nabla operator), or . The Laplace operator is named after the French mathematician Pierre-Simon de Laplace (1749–1827), who first applied the operator to the study of celestial mechanics: the Laplacian of the gravitational potential due to a given mass density distribution is a constant multiple of that density distribution. The Laplacian occurs in many differential equations describing physical phenomena.

Multiverse | DC Database | FANDOM powered by Wikia The Multiverse consists of multiple universes existing in the same physical space, kept separate by differing vibrational speeds. History The Multiverse consists of multiple universes existing in the same physical space, kept separate by differing vibrational speeds. The Original Multiverse History In the Beginning Krona was a member of the ancient race of powerful, blue-skinned immortals from the planet Maltus. Flash of Two Worlds From the perspective of the Earth-One Universe, the first transuniversal journey occurred when The Flash (Barry Allen) accidentally changed his vibrational frequency to match that of Earth-Two, where he met Jay Garrick, the Golden Age Flash and his childhood comic book hero. As Allen explained to Garrick in their first meeting: Crime Syndicate Over the years, various other Earths were visited by super-heroes (and villains). Passage of Time The End of All Things The Anti-Monitor revealed to the assembled heroes that he lured them to him to absorb their life forces. Notes
