Can Acceleration Phase Account for the Observed Accelerating Expansion of the Universe?

Authors: Karan R.Takkhi

A new cosmological era began with the discovery of accelerating expansion of the Universe. The deviation of the Hubble diagram from exhibiting a linear distance-redshift relation at high redshifts provides the very crucial clue to support this discovery. In this paper I present a theory to account for the observed accelerating expansion of the Universe. I discuss that the Universe should attain a constant rate of expansion in future, given the linear distance-redshift relation being obeyed by the receding large-scale structures within the local Universe, suggesting constant recessional velocities. I compare the local Universe within which the receding large-scale structures exhibit the linear distance-redshift relation in accordance with the Hubble diagram, and the remote Universe within which the receding large-scale structures deviate from exhibiting the expected linearity. There may be a simple terminology termed by me as “acceleration phase” that would probably account for the observed acceleration, particularly for the receding large-scale structures belonging to the remote Universe that exhibit high redshifts.
