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 …

Since string theory is quantum mechanics of a relativistic string, the foundations of the subject can be explained to students exposed to both special relativity and basic quantum mechanics.

Apr 12, 2025 · Throughout the 2010s and into the 2020s, string theory remains a central theory in fundamental physics, continuing to evolve and find new connections, even as it awaits direct …

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 …

May 20, 2025 · The reason is the potential payoff: string theory provides a possible solution to some of the deepest puzzles in physics. It offers a unified description of nature: matter and forces all coming …

May 23, 2025 · Instead of imagining the fundamental building blocks of the universe as zero-dimensional points (as in the Standard Model of particle physics), String Theory envisions them as minute …

5 days ago · Different patterns of string vibrations correspond to different particles. String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply …

Jun 4, 2025 · A look into string theory and its implications for the universe. String theory is a framework in theoretical physics that tries to explain how the universe...

Jan 29, 2025 · These are lecture notes of the introductory String Theory course held by one of the au-thors for the master program of Theoretical Physics at Turin University. The world-sheet approach to …
