NOVA: You mentioned unified field theory. If string theory does lead to the so-called "theory of everything"—I know you don't like that term much—where would theoretical physicists go from there?

String theory suggests that the most fundamental building blocks of the universe are not particles like electrons or quarks, but tiny, vibrating strings of energy. It is the vibration and arrangement ...

String field theory co-founder Michio Kaku did not even try to explain his controversial yet undeniably brilliant cosmological theory of everything during his interview on Reddit, beyond this ...

In other words, that makes it almost impossible to falsify, and consequently should disqualify it as a valid field of research. While some attempts to give string theory predictive power are ...

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 ...

This work has implications for open topological field theories and string field theory, further bridging the gap between algebra and topology[3]. Moreover, the study of stratified vector bundles ...

including string theory, classical and quantum gravity, quantum field theory, holography, quantum information theory, hard condensed matter theory, quantum statistical mechanics, theoretical cosmology ...

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 ...
