Abstract

Simple Summary We briefly review the problem of time in quantum cosmology and present two possible solutions. Time in quantum gravity is not a well-defined notion despite its central role in the very definition of dynamics. Using the formalism of quantum geometrodynamics, we briefly review the problem and illustrate it with two proposed solutions. Our main application is quantum cosmology-the application of quantum gravity to the Universe as a whole.
