Nevertheless, some physicists are drawn to M-theory because of its degree of uniqueness and rich set of mathematical properties, triggering the hope that it may describe our world within a single framework.
 
One feature of M-theory that has drawn great interest is that it naturally predicts the existence of the [[graviton]], a [[Spin (physics)|spin-2]] particle hypothesized to mediate the gravitational force. Furthermore, M-theory naturally predicts a phenomenon that resembles [[black hole evaporation]]. Competing unification theories such as [[asymptotically safe gravity]], [[An Exceptionally Simple Theory of Everything|E8 theory]], [[noncommutative geometry]], and [[causal fermion systems]] have not demonstrated any level of mathematical consistency. Another approach to quantum gravity is [[loop quantum gravity]], a non-unifying theory; many physicists consider loop quantum gravity to be less elegant than M-theory because it posits gravity to be completely different from the other fundamental forces.<ref name=atlantic/><ref name=quanta/>
