The evolution of the Universe is considered by means of a nonlinear realization of afˇne and conformal symmetries via MaurerÄCartan forms. Conformal symmetry is realized by the geometry of similarity with the Dirac scalar dilaton. We provide preliminary quantitative evidence that the zeroth harmonic of the Dirac scalar dilaton may lead to observationally viable cosmology, where the type Ia supernova luminosity distances Ä redshift relation can be explained by vacuum dilaton dark energy. The diffeo-invariance of spin connection coefˇcients of the afˇne formulation leaves only one degree of freedom of strong gravitation waves. We discuss that the dark matter effect in spiral galaxies can be described by the gravitation waves expressed through the spin connection coefˇcients of the afˇne formulation. We show that the evolution equations of the afˇne gravitons with respect to the dilaton zeroth mode coincide with the equations of ®squeezed oscillator¯. The list of theoretical and observational arguments is given in favor of that the origin of the Universe can be described by quantum vacuum creation of these squeezed oscillators.
