Cosmological constant as a fundamental constant

Abstract

We consider further consequences of recently [1] revealed role of cosmological constant Λas of a physical constant, along with the gravitational one to define the gravity i.e. the General Relativity and its low-energy limit. We now show how Λ-constant affects the basic relations involving the Planck units and leads to emergence of a new dimensionless quantity (constant) which can be given cosmological information content. Within Conformal Cyclic Cosmology this approach implies the possibility of rescaling of physical constants from one aeon to another; the rescaling has to satisfy a condition involving Λand admitting group symmetry. The emerged dimensionless information constant enables to reduce the dynamics of the universe to an algorithm of discrete steps of information increase.
