May 18, 2023 · String theory is a framework that physicists use to describe how forces usually conceptualized on a gigantic level, like gravity, could affect tiny objects like electrons and protons.
String theory. Victor de Schwanberg/Alamy. String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable...
String theory is a candidate for a unified theory of the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and gravity. Particles in string theory are identified with particular patterns of vibration of a one-dimensional elementary object called a string.
Apr 25, 2022 · String theory is a theoretical framework to address the shortcomings of Einstein's theory of general relativity and quantum physics - two primary tools for understanding modern physics. String theory is often referred to as the theory of everything - a just identification given its ability to bridge the gap between gravity and quantum physics.

Apr 15, 2009 · By Michael Marshall. 15 April 2009. Victor de Schwanberg/Alamy. String theory is the idea that the fundamental particles we observe are not point-like dots, but rather tiny strings. String...
According 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.
