WebMar 26, 2016 · It was ultimately shown that only two mathematical symmetry groups could be applied to heterotic string theory, which resulted in stable theories in ten dimensions — O(32) symmetry and E 8 x E 8 symmetry. These two groups gave rise to the names Type HO and Type HE string theory. Type HO string theory: Type HO is a form of heterotic string ... WebFor one, some of its equations showed signs of being inconsistent; for another, the mathematics of the theory demanded the universe have not just the three spatial dimensions of common experience but six others (for a total of nine spatial dimensions, or a total of ten space-time dimensions).

WebDec 1, 2007 · String theory is no different and many mathematicians work on ideas inspired by it. These include the possible geometries of the hidden dimensions, the basic ideas of geometry when there is a minimum distance, the ways in which strings can split and come together, and the question of how we can relate strings to the particles in the world that ... WebAccording to the theory, the strings are so small that they appear to be points—as particles had long been thought to be—but in reality they have length (about 10 −33 cm); the mass and charge of a particle is determined by how a string vibrates. imagine dragons - demons official music video

One popular way of deriving realistic physics from string theory is to start with the heterotic theory in ten dimensions and assume that the six extra dimensions of spacetime are shaped like a six-dimensional Calabi–Yau manifold. Such compactifications offer many ways of extracting realistic physics … See more In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through … See more In general relativity, a black hole is defined as a region of spacetime in which the gravitational field is so strong that no particle or radiation … See more One approach to formulating string theory and studying its properties is provided by the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. This is a theoretical result which implies that string theory is in some cases equivalent to a quantum field … See more Overview In the 20th century, two theoretical frameworks emerged for formulating the laws of physics. The … See more Prior to 1995, theorists believed that there were five consistent versions of superstring theory (type I, type IIA, type IIB, and two versions of heterotic string theory). This … See more In addition to being an idea of considerable theoretical interest, string theory provides a framework for constructing models of real-world physics that combine … See more In addition to influencing research in theoretical physics, string theory has stimulated a number of major developments in pure mathematics. Like many developing … See more WebString theory intriguingly suggests that six more dimensions exist, but are somehow hidden from our senses. They could be all around us, but curled up to be so tiny that we have never realized their existence. What is a dimension? Dimensions are really just the number of co-ordinates we need to describe things. Web1 day ago · One is string theory, which suggests the universe is ultimately made up of tiny, vibrating strings. Another is loop quantum gravity, which suggests Einstein’s space-time arises from quantum effects. imagine dragons discography wiki
