The emergent semiclassical time approach to resolving the problem of time in quantum gravity is considered in the arena of relational particle toy models. In situations with 'heavy' and 'light' degrees of freedom, two notions of emergent semiclassical WKB time emerge; these are furthermore equivalent to two notions of emergent classical 'Leibniz–Mach–Barbour' time. I study the semiclassical approach, in a geometric phase formalism, extended to include linear constraints, and with particular… Expand

TLDR
It is shown that cosmology as a theory of the mean is meaningful and the Schr\"odinger equation for matter is obtained in conformity with previous work where these particular questions were not addressed. Expand

Loop Quantum Cosmology
TLDR
L loop quantum cosmology is an application of loop quantum gravity to homogeneous systems, which removes classical singularities and introduces the main effects of quantum effects into effective classical equations, which allow one to avoid the interpretational problems of quantum theory. Expand
