Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a significant ...

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 ...

String theory aims to explain all fundamental forces and particles in the universe—essentially, how the world operates on the smallest scales. Though it has not yet been experimentally verified, work ...

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

Geometric methods underpin much of modern string and field theory, offering a unifying language to describe the rich tapestry of spacetime, gauge symmetries and dualities. Classical differential ...

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 universe. The ...
