In addition to the problem of developing a consistent theory of quantum gravity, there are many other fundamental problems in the physics of atomic nuclei, black holes, and the early universe. [a] String theory is a theoretical framework that attempts to address these questions and many others.
The quantum multiverse creates a new universe when a diversion in events occurs, as in the real-worlds variant of the many-worlds interpretation of quantum mechanics. Holographic The holographic multiverse is derived from the theory that the surface area of a space can encode the contents of the volume of the region. Simulated
One of the earliest documented attempts to apply brane cosmology as part of a conceptual theory is dated to 1983. [ 5 ] The authors discussed the possibility that the Universe has ( 3 + N ) + 1 {\displaystyle (3+N)+1} dimensions, but ordinary particles are confined in a potential well which is narrow along N {\displaystyle N} spatial directions ...
Superstringtheory.com – The "Official String Theory Web Site", created by Patricia Schwarz. References on string theory and M-theory for the layperson and expert. Not Even Wrong – Peter Woit's blog on physics in general, and string theory in particular. M-Theory – Edward Witten (1995) – Witten's 1995 lecture introducing M-Theory.
Leonard Susskind’s The Cosmic Landscape: String Theory and the Illusion of Intelligent Design surveys the new debate clearly and amusingly for the general reader. Susskind, one of the inventors of string theory and a leading advocate of the landscape and multiverse ideas, does an excellent job developing the necessary background in quantum ...
String theory is a branch of theoretical physics that attempts to build a theory of quantum gravity using one-dimensional strings rather than zero-dimensional point particles as fundamental building blocks. The name string theory is somewhat of a misnomer since the modern theory also includes higher dimensional objects known as branes
In string theory the number of flux vacua is commonly thought to be roughly , [4] but could be , [5] or higher. The large number of possibilities arises from choices of Calabi–Yau manifolds and choices of generalized magnetic fluxes over various homology cycles, found in F-theory .
The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory is a book by Brian Greene published in 1999, which introduces string and superstring theory, and provides a comprehensive though non-technical assessment of the theory and some of its shortcomings.
