Abstract

Quantization of general relativity in four dimensions is not straightforward because Newton's constant carries units of (length)^2 which means the theory is non-renormalizable. Up to now, the only quantum-mechanical approach which has allowed the perturbative computation of graviton scattering at all energy scales is superstring theory. Although it might be a long time before experimental tests of quantum gravity will be able to tell us if superstring theory correctly describes our universe, the theory has other interesting properties such as supersymmetry and duality symmetry whose study has been useful for several branches of physics and mathematics.
