The Graviton and the Nature of Dark Energy

TL;DR

This paper explores the nature of dark energy and the cosmological constant, proposing a decay model where the constant diminishes over the universe's age, offering a new perspective on the dark energy paradox.

Contribution

It introduces a novel decay model for the cosmological constant, linking it to fundamental constants and the universe's age, providing a fresh approach to the dark energy problem.

Findings

Proposes a decay law for the cosmological constant involving fundamental constants and universe age.

Suggests the cosmological constant may not be truly constant but dynamic over cosmic timescales.

Abstract

I discuss various thoughts, old and new, about the cosmological constant (or dark energy) paradox. In particular, I suggest the possibility that the cosmological ``constant'' may decay as $\Lambda \sim \alpha^2 m_N^3 / \tau$, where $\tau$ is the age of the universe.
