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 …

Nov 21, 2025 · String theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity. The name string theory comes from the modeling of …

May 29, 2025 · For decades, string theory has been hailed as the leading candidate for the theory of everything in our universe. Yet despite its mathematical elegance, the theory still lacks empirical …

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known...

May 20, 2025 · In current physics, particles like electrons or quarks are treated as point-like objects. String theory, however, proposes that these particles are not zero-dimensional points but rather tiny …

It is a quantum theory that aims at reproducing the interaction and symmetry structure of a gauge field theory. Within this framework, the basic idea of string theory is a fairly simple one: the point-like …

Apr 12, 2025 · Students interested in the cutting-edge of quantum computing and quantum information may be surprised to learn that string theory is influencing that field too, by providing examples of …

1.1 Why do we study string theory? • For quantum gravity of all the forces in Nature. The standard model has unified electromagnetic, weak and strong force based on quantum field theories whereas …

By replacing point-like particles with one-dimensional strings vibrating in a higher-dimensional space, string theory offers a unique perspective on the fundamental nature of reality, combining principles …

Topics of current research include: What role does quantum information play in formulating quantum field theories and how does it elucidate the duality between particles and strings?
