A Newtonian approach to quantum gravity is studied. At least for weak gravitational fields, it should be a valid approximation. Such an approach can be used to point out problems and prospects inherent in a more exact theory of quantum gravity, yet to be discovered. Newtonian quantum gravity, e.g., shows promise for prohibiting black holes altogether (which would eliminate singularities and also solve the black hole information paradox), gives gravitational radiation even in the spherically symmetric case, and supports nonlocality (quantum entanglement). Its predictions should also be testable at length scales well above the “Planck scale” by high-precision experiments feasible with existing technology.
