The observation that expansion of our universe is accelerating suggests the existence of an unknown energy source, dark energy. The observed large-scale structure of our universe indicates the existence of an unknown matter source, dark matter. Cosmological constant, a constant term related to the vacuum energy appearing in the equation of gravitational field, is the simplest possible form of dark energy. String theory is one of the few mathematically consistent theories that can unify quantum physics and general relativity. In this work, we present a new way to derive and interpret string theory. We show that this new interpretation of string theory can explain the source of dark energy and dark matter. It may provide a way to calculate cosmological constant consistent with the current data.
