Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature's forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe, conveyed through the exchange of virtual bosons. In electromagnetism, the ...

Ashoke Sen, an acclaimed theoretical physicist hailing from Kolkata, received the prestigious Oskar Klein Medal in 2026. His groundbreaking contributions have significantly advanced string theory, ...

The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

String theory seeks to describe fundamental interactions by modelling particles as one-dimensional strings. In efforts to unify quantum mechanics and general relativity, it introduces additional ...

Matrix models constitute a powerful nonperturbative framework in which quantum fields and the geometry of space–time are encoded in large matrices. Originally motivated by attempts to formulate string ...

Hasbrouck 134. Refreshments at 3:45. Presentation begins at 4:00. "New Approaches to Quantum Gravity and String Theory" The unification of quantum mechanics and general relativity remains a mystery, ...

Quantum mechanics has journeyed from a strange and controversial idea to the foundation of some of humanity’s most advanced technologies. Now researchers are pushing its boundaries even further, with ...

Recent research shows that gravity and quantum information are deeply connected and that the shape of spacetime can be traced back to the way information is stored in quantum fields. Einstein's theory ...
