摘要: I briefly review the current status of quantum gravity. After giving some general motivations for need such a theory, discuss main approaches in quantizing relativity: Covariant (perturbation effective and path integrals) canonical (quantum geometrodynamics, loop gravity). then address gravitational aspects string theory. This is followed by discussion black holes cosmology. end with remarks on observational
