# Cosmological constant as a fundamental constant

## TL;DR

This paper explores the role of the cosmological constant as a fundamental physical constant, revealing its impact on Planck units, the emergence of a new dimensionless constant, and implications for cosmological models like Conformal Cyclic Cosmology.

## Contribution

It introduces a new dimensionless constant linked to mbda, showing how it influences fundamental relations and enables a discrete, information-based view of cosmic evolution.

## Key findings

- mbda affects Planck units and fundamental relations.
- A new dimensionless information constant is identified.
- Implications for rescaling physical constants in cyclic cosmology.

## Abstract

We consider further consequences of recently [1] revealed role of cosmological constant \Lambda as 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 \Lambda-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 \Lambda and 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.
