In the cosmological context, it is often argued that all physical events that happened before inflation are washed out by the latter, such that a priori quantum cosmology models are not testable. In this talk, based on arXiv:1508.06786 and arXiv:1510.08766, I am going to present cosmological results obtained by investigation of a quantum cosmology scenario within the loop approach that can be compared to observations, and refute in this way the above assertion. In particular, I will present the primordial power spectrum of scalar perturbations in loop quantum cosmology within the deformed algebra approach, and with a massive scalar field as the matter content of the Universe, which allows us to generate the angular power spectrum as it was measured very recently by cosmologists (PLANCK Collaboration 2015). The results will be compared to these observations, showing an incompatibility with the latter. This refutes the initial hypothesis that, in general, quantum cosmology models cannot be falsified.
