On de Sitter Universe

Authors: Zlatan Stojanovic

In this letter I address the model which stems from the de Sitter space-time. We can consider empty de Sitter space-time as the Universe where space metrics i.e. expansion of space is a consequence of decrease of time elongation during evolution of Universe i.e. curved time. In de Sitter metric this is represented by the relation distance-time elongation and by the acceleration of expansion of space. New model explains that de Sitter cosmological time is proper time of the Universe. The cosmological time curvature interacts with photon's energy from distant galaxies like in classical gravitational redshift. Empty de Sitter represents inertial state of Universe. What this proposal contributes to de Sitter universe is variable cosmological constant i.e. parameter. Cosmological parameter is represented in the change of time curvature which we can correlate to the change of photons' energy of distant galaxies and CMBR in time. Keywords: de Sitter space-time, curved time, dark energy, de Sitter effect
