This model predicts effective inverse square-law dependence of the mean total energy density <\\rho> on the expectation value of cosmological scale factor where the averaging is performed over the state with large quantum numbers. Such a law of decreasing of <\\rho> during the expansion of the universe allows to describe the observed coordinate distances to type Ia supernovae and radio galaxies in the redshift interval z = 0.01 - 1.8. A comparison with phenomenological models with the cosmological constant (\\Lambda CDM) and with zero dark energy component (\\Omega_{M} = 1) is made. It is shown that observed small deviations of the coordinate distances to some sources from the predictions of above mentioned simple quantum model can be explained by the fluctuations \\delta a of the scale factor about the average value . These fluctuations can arise due to finite widths of quasistationary states in the early universe. During expansion the fluctuations \\delta a grow with time and manifest themselves in the form of observed relative increase or decrease of coordinate distances. The amplitudes of fluctuations \\delta a/ calculated from observed positions of individual supernovae are in good agreement with their estimations in quantum theory. Possible consequences from the conclusions of quantum theory are discussed.", "revisions": [ { "version": "v1", "updated": "2004-05-24T09:16:07.000Z" } ], "analyses": { "keywords": [ "energy density", "quantum cosmology", "coordinate distances", "consequences" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "inspire": 650852, "adsabs": "2004astro.ph..5454K" } } }
