In the ongoing search for a “theory of everything” — a single theoretical framework that can explain the four basic forces — one contender that has emerged is string theory. Now, a new study in Physical Review Letters has found that a key equation describing string theory naturally emerges from just a small number of physical axioms — pulling itself up by its own “bootstraps,” per se. These results could offer a starting point towards a better understanding of quantum gravity: https://go.aps.org/3QYAoHg
