Theory of everything

Theory of everything
A theory of everything (ToE) or final theory, ultimate theory, or master theory is a hypothetical single, all-encompassing, coherent theoretical framework of physics that fully explains and links together all physical aspects of the universe.[1]:6 Finding a ToE is one of the major unsolved problems in physics. Over the past few centuries, two theoretical frameworks have been developed that, as a whole, most closely resemble a ToE. The two theories upon which all modern physics rests are general relativity (GR) and quantum field theory (QFT). GR is a theoretical framework that only focuses on the force of gravity for understanding the universe in regions of both large-scale and high-mass: stars, galaxies, clusters of galaxies, etc. On the other hand, QFT is a theoretical framework that only focuses on three non-gravitational forces for understanding the universe in regions of both small scale and low mass: sub-atomic particles, atoms, molecules, etc. Historical antecedents[edit] [edit]

Timeline of the universe Using observatories on the earth and in space, astronomers have been able to study the nature of the cosmos in unprecedented detail. By analysing the motion of distant galaxies, they have discovered that the whole cosmos is expanding under the influence of forces unleashed at its birth in the big bang. Combined with studies of the radiation left over from that primordial explosion, they have found that the universe was born 13.7bn years ago, give or take 200m years. Pinning down the date of creation with such precision is impressive, but scientists have gone much further.

An Exceptionally Simple Theory of Everything "An Exceptionally Simple Theory of Everything"[1] is a physics preprint proposing a basis for a unified field theory, very often referred to as "E8 Theory,"[2] which attempts to describe all known fundamental interactions in physics and to stand as a possible theory of everything. The paper was posted to the physics arXiv by Antony Garrett Lisi on November 6, 2007, and was not submitted to a peer-reviewed scientific journal.[3] The title is a pun on the algebra used, the Lie algebra of the largest "simple", "exceptional" Lie group, E8. The theory received accolades from a few physicists[citation needed] amid a flurry of media coverage, but also met with widespread skepticism.[4] Scientific American reported in March 2008 that the theory was being "largely but not entirely ignored" by the mainstream physics community, with a few physicists picking up the work to develop it further.[5]

Technicolor (physics) Technicolor theories are models of physics beyond the standard model that address electroweak gauge symmetry breaking, the mechanism through which W and Z bosons acquire masses. Early technicolor theories were modelled on quantum chromodynamics (QCD), the "color" theory of the strong nuclear force, which inspired their name. In order to produce quark and lepton masses, technicolor has to be "extended" by additional gauge interactions. Particularly when modelled on QCD, extended technicolor is challenged by experimental constraints on flavor-changing neutral current and precision electroweak measurements. General relativity General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916[1] and the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light.

How Does Theta Work The scientific basis of ThetaHealing® consists of two main categories, quantum and epigenetic: Quantum StuffWe are quantum beings. This simple fact is the beginning of understanding how and why ThetaHealing® works. We are not merely physical beings, made of matter. 'Existentialism' Existentialism is a term applied to the work of certain late 19th- and 20th-century philosophers who, despite profound doctrinal differences,[1][2][3] shared the belief that philosophical thinking begins with the human subject—not merely the thinking subject, but the acting, feeling, living human individual.[4] In existentialism, the individual's starting point is characterized by what has been called "the existential attitude", or a sense of disorientation and confusion in the face of an apparently meaningless or absurd world.[5] Many existentialists have also regarded traditional systematic or academic philosophies, in both style and content, as too abstract and remote from concrete human experience.[6][7] Definitional issues and background[edit] There has never been general agreement on the definition of existentialism. The term is often seen as an historical convenience as it was first applied to many philosophers in hindsight, long after they had died. Concepts[edit]

Is reality digital or analog ? Essay - FQXi Community CATEGORY:FQXi Essay Contest - Is Reality Digital or Analog?[back]TOPIC:Is Reality Digital or Analog? by Jarmo Matti Mäkelä[refresh] Author Jarmo Matti Mäkelä wrote on Feb. 1, 2011 @ 17:21 GMT Essay Abstract A report of a discussion with Isaac Newton. String theory String theory was first studied in the late 1960s[3] as a theory of the strong nuclear force before being abandoned in favor of the theory of quantum chromodynamics. Subsequently, it was realized that the very properties that made string theory unsuitable as a theory of nuclear physics made it a promising candidate for a quantum theory of gravity. Five consistent versions of string theory were developed until it was realized in the mid-1990s that they were different limits of a conjectured single 11-dimensional theory now known as M-theory.[4] Many theoretical physicists, including Stephen Hawking, Edward Witten and Juan Maldacena, believe that string theory is a step towards the correct fundamental description of nature: it accommodates a consistent combination of quantum field theory and general relativity, agrees with insights in quantum gravity (such as the holographic principle and black hole thermodynamics) and has passed many non-trivial checks of its internal consistency.
