Oct 28, 2003 路 Brian Greene delves into the nuts, bolts, and outright nuttiness of string theory. Part 2, "String's the Thing," opens with a whimsical scene in a movie theater in which the history of the String theory is a candidate for a unified theory of the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and gravity. Particles in string theory are identified with particular patterns of vibration of a one-dimensional elementary object called a string. String theory is a quantum theory in that the mass spectrum of strings is discrete, so string theory is Unified field theory. In physics, a unified field theory ( UFT) is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a pair of physical and virtual fields. According to modern discoveries in physics, forces are not transmitted directly between interacting May 19, 2006 路 These proceedings are based on lectures delivered at the "RTN Winter School on Strings, Supergravity and Gauge Theories", CERN, January 16 - January 20, 2006. The school was mainly aimed at Ph.D. students and young postdocs. The lectures start with a brief introduction to spacetime singularities and the string theory resolution of certain static singularities. Then they discuss attempts to Mar 8, 2011 路 Another possible test for string theory will be analyzing the detailed observations of the light left over from the Big Bang, called the cosmic microwave background radiation, which permeates space. Jul 26, 2023 路 The Big Bang Theory is the leading explanation for how the universe began. Simply put, it says the universe as we know it started with an infinitely hot and dense single point that inflated and Apr 10, 2014 路 "The Relationship Diremption" is the twentieth episode of the seventh season of the American sitcom The Big Bang Theory. The episode aired on Thursday, April 10, 2014. Sheldon is depressed over his lack of progress in his twenty years of work on string theory. Howard and Bernadette go out with Raj and Emily who had an earlier very embarrassing date with Howard. In the Caltech cafeteria, the In string cosmology, this arises from the so-called dilaton field. This is a scalar term entering into the description of the bosonic string that produces a scalar field term into the effective theory at low energies. The corresponding equations resemble those of a Brans鈥揇icke theory . Analysis has been worked out from a critical number of Supersymmetry is a specific mathematical relationship between certain elements of physics equations. It was discovered outside of string theory, although its incorporation into string theory transformed the theory into supersymmetric string theory (or superstring theory) in the mid-1970s. One benefit of supersymmetry is that it vastly .
