WebJan 21, 2024 · String theory also requires the existence of 10 space-time dimensions for the strings to wiggle around in. Yet we haven’t found any supersymmetric partner particles, and our universe looks 4D, with three dimensions of space and one of time. WebJan 20, 2024 · String theory math required six additional dimensions (for a total of 10) visible only to the little strings, much as a powerline looks like a 1D line to birds flying far overhead but a 3D...

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.
