Quantum cosmology; loop quantum cosmology; inflation
The status of quantum cosmologies as testable models of the early universe is assessed in the context of inflation. While traditional WheelerDeWitt quantization is unable to produce sizable effects in the cosmic microwave background, the more recent loop quantum cosmology can generate potentially detectable departures from the standard cosmic spectrum. Thus, present observations constrain the parameter space of the model, which could be made falsifiable by near-future experiments.
