Читать книгу String Theory For Dummies - Andrew Zimmerman Jones - Страница 24

Currently, four fundamental forces (more precisely called “interactions” by physicists) are known to physics: gravity, electromagnetic force, weak nuclear force, and strong nuclear force. String theory creates a framework in which all four of these interactions were once a part of the same unified force of the universe.

Under this theory, as the early universe cooled off after the big bang, this unified force began to break apart into the different forces we experience today. Experiments at high energies may someday allow us to detect the unification of these forces, although such experiments are well outside our current realm of technology.
