Solving the problem of cosmological singularity is one of the keys to unifying theory of gravitation with quantum physics. In the cosmology context, the solution may help to understand the structure of the CMB spectrum, solve the dark energy problem, and enable understanding the origin of cosmological inflation.

Quantum cosmology theories may be directly tested by confrontation of conclusions of the theory predicting quantum generation of gravitational waves with observables supplied by the WMAP, QUaD, BICEP and PLANCK satellite missions, as well as by the LIGO and Virgo terrestrial gravitational interferometers.
