In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...

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 ...

Quantum field theory (QFT) realises particles as excitations of underlying fields that permeate spacetime. By quantising classical gauge and matter fields, QFT unifies quantum mechanics with special ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...
