Читать книгу String Theory For Dummies - Andrew Zimmerman Jones - Страница 22

To many physicists, the goal of string theory is to be a “theory of everything” — that is, to be the single physical theory that, at the most fundamental level, describes all of physical reality. If successful, string theory could explain many of the fundamental questions about our universe.

To others, the goal is more modest: String theory is a working theory of quantum gravity, and arguably the only one we truly understand. Studying string theory can produce important insights into the nature of quantum gravity, one of the key open questions in physics.
