Specifically for the cosmological data, the law of selfvariations predicts and justifies: the redshift of distant astronomical objects and Hubble's law, the cosmic microwave background radiation, the large-scale structures of matter in the Universe, the fact that the Universe is flat, the fact that the total energy-content of the Universe is zero, the fact that the very early Universe went through a phase of ionization, the arrow of time in the macrocosm and its breakdown in the microcosm, the fact that the luminosity distances of distant astronomical objects will always be measured larger than the actual distances.
