In the context of string theory, he literally floods the pages of his book with undefendable speculations about some basic results of string theory. Because these statements are of mathematical nature, we are sure that Lee is wrong even in the absence of any experiments.
String theory is a theoretical framework that attempts to address these questions. The starting point for string theory is the idea that the point-like particles of particle physics can also be modeled as one-dimensional objects called strings. String theory describes how strings propagate through space and interact with each other.
One attempt to formulate string theory in a manifestly background-independent fashion is string field theory, but little progress has been made in understanding it. Another approach is the conjectured, but yet unproven AdS/CFT duality , which is believed to provide a full, non-perturbative definition of string theory in spacetimes with anti-de ...
The history of string theory spans several decades of intense research including two superstring revolutions. Through the combined efforts of many researchers, string theory has developed into a broad and varied subject with connections to quantum gravity, particle and condensed matter physics, cosmology, and pure mathematics.
In string theory, the strings may be open (forming a segment with two endpoints) or closed (forming a loop like a circle) and may have other special properties. [1] Prior to 1995, there were five known versions of string theory incorporating the idea of supersymmetry (these five are known as superstring theories) and two versions without supersymmetry known as bosonic string theories, which ...
String theory is not a theory but a theory that a theory could exit. There is no string theory. That is what Voit means by "Not even wrong." There are 10^500 string theories. 40 years of work have gotten physics no closer to finding the right one. Five different string theories can be combined in any ratio to each other to form the resulting ...
Invisible string theory is the idea that you and your soulmate are "connected through an invisible string or a thread" and it's "written in the universe" that you’ll be together one day, says ...
In 1974, Joël Scherk and John Schwarz suggested that string theory was therefore not a theory of nuclear physics as many theorists had thought but instead a theory of quantum gravity. [53] At the same time, it was realized that hadrons are actually made of quarks, and the string theory approach was abandoned in favor of quantum chromodynamics.
