TL;DR
This paper investigates the cosmological constant and Hubble parameter within Weyl gravity, deriving their current values as functions of space and time, aligning well with observed universe parameters.
Contribution
It introduces a novel approach by treating the cosmological constant and Hubble parameter as functions in Weyl gravity and derives their current values.
Findings
Derived current values of Hubble parameter and cosmological constant in Weyl gravity.
Results agree with observed universe parameters.
Supports Weyl gravity as a viable framework for cosmology.
Abstract
In this paper, the cosmological "constant" and the Hubble parameter are considered in the Weyl theory of gravity, by taking them as functions of and , respectively. Based on this theory and in the linear approximation, we obtain the values of and which are in good agreement with the known values of the parameters for the current state of the universe.
