Dual Graviton In theoretical physics , the DUAL GRAVITON is a hypothetical elementary particle that is a dual of the graviton under electricmagnetic duality predicted by some formulations of supergravity in eleven dimensions. The dual graviton was first hypothesized in 1980 (in a paper received by the journal on Einstein's 101st birthday). It was theoretically modeled in 2000s, which was then predicted in elevendimensional mathematics of SO(8) supergravity in the framework of electricmagnetic duality. It again emerged in the E11 generalized geometry in eleven dimensions, and the E7 generalized vielbeinegeometry in eleven dimensions. While there is no local coupling between graviton and dual graviton, the field introduced by dual graviton may be coupled to a BF model as nonlocal gravitational fields in extra dimensions [...More...]  "Dual Graviton" on: Wikipedia Yahoo

Quantum Gravity QUANTUM GRAVITY (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics , and where quantum effects cannot be ignored. The current understanding of gravity is based on Albert Einstein Albert Einstein 's general theory of relativity , which is formulated within the framework of classical physics . On the other hand, the other three fundamental forces of physics are described within the framework of quantum mechanics and quantum field theory , radically different formalisms for describing physical phenomena. It is sometimes argued that a quantum mechanical description of gravity is necessary on the grounds that one cannot consistently couple a classical system to a quantum one. However, Robert Wald appeared to refute that by providing an explicit construction of a consistent semiclassical theory [...More...]  "Quantum Gravity" on: Wikipedia Yahoo 

Twistor String Theory TWISTOR STRING THEORY is an equivalence between N = 4 supersymmetric Yang–Mills theory and the perturbative topological B model string theory in twistor space . It was initially proposed by Edward Witten Edward Witten in 2003. Twistor theory was introduced by Roger Penrose Roger Penrose from the 1960s as a new approach to the unification of quantum theory with gravity. Twistor space is a threedimensional complex projective space in which physical quantities appear as certain structural deformations. Spacetime and the familiar physical fields emerge as consequences of this description. But twistor space is chiral (handed) with left and righthanded objects treated differently. For example, the graviton for gravity and the gluon for the strong force are both righthanded. During this period, Edward Witten Edward Witten was a leading developer of string theory [...More...]  "Twistor String Theory" on: Wikipedia Yahoo 

Theory Of Everything A THEORY OF EVERYTHING (TOE), FINAL THEORY, ULTIMATE THEORY, or MASTER THEORY is a hypothetical single, allencompassing, coherent theoretical framework of physics that fully explains and links together all physical aspects of the universe . :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. These 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 gravity for understanding the universe in regions of both largescale and highmass: stars, galaxies, clusters of galaxies, etc. On the other hand, QFT is a theoretical framework that only focuses on three nongravitational forces for understanding the universe in regions of both small scale and low mass: subatomic particles, atoms, molecules, etc [...More...]  "Theory Of Everything" on: Wikipedia Yahoo
