Abstract
We consider it worthy if we could construct a realistic model universe that would enable us to identify a clue about the source of dark energy. So, we develop a Scale Covariant Theory model universe considering a 5D spherically symmetric space-time. It is predicted that the constructed model itself behaves as a phantom energy model/ source that tends to a de Sitter phase avoiding the finite-time future singularity (big rip). The model universe is isotropic and is free from an initial singularity. The gravitational constant [Formula: see text] decreases with a variation of [Formula: see text][Formula: see text] and the Hubble parameter is estimated to be [Formula: see text]. We also provide a thorough analysis of the cosmological findings with graphical representations.
