String Theory

The special relative speed of light speed is the limit speed of the universe. Regardless of the relative position, light travels at the same speed. When applied to Newtonian physics, it provides a new relativistic formula for motion. 4 Quantum Theory Heat bodies emit electromagnetic radiation. When the energy carried away by radiation is added together, the total energy generated is calculated as infinity. Max Planck speculates that when energy is emitted in discrete packets (quantum) it will be a finite amount of energy.

String theory in elementary particle physics is a theory trying to combine quantum mechanics with general relativity of Albert Einstein. Name string theory comes from the modeling of elementary particles as a small one - dimensional "code - like" entity, not a traditional way of modeling primitive particles as zero - dimensional point particles. The theory assumes that strings experiencing a particular vibration mode correspond to particles having specific properties such as mass and charge. In the 1980's, physicists noticed that string theory could combine all four natural forces - gravity, electromagnetic force, weakness - and all kinds of matter in the framework of quantum mechanics. - Unified Field Theory

In 1984's first superstring revolution, many physicists changed string theory to particle physics and unified theory of quantum gravity. Unlike the supergravity theory, string theory can adapt to the chirality of the standard model and can provide a gravity theory consistent with the quantum effect. Another characteristic of the string theory that many physicists were fascinated in the 1980s and 1990s is its high degree of uniqueness. In ordinary particle theory one can consider any set of elementary particles whose classical behavior is described by any Lagrangian matrix. In string theory, the possibilities are more limited. By the 1990's, physicists believed in theory that there were only 5 supersymmetric versions in theory.

One of the major developments of string theory over the past few decades was the discovery of mathematical transformations linking one physics theory to another, a "duality". Physicists who studied string theory have discovered many of these dualities between different versions of string theory. It led to the hypothesis that all consistent versions of the string theory are combined into a single frame called the M theory. It is inside. String theory studies also produced a lot of results on the nature of black holes and the interaction of gravity. Several paradoxes arise when people try to understand the quantum aspects of black holes, and string theory studies attempt to reveal these problems. At the end of 1997, this series of research finally found anti-de Sitter / conformal field theory correspondence or AdS / CFT
