A note on the estimation of the mass of the universe

TL;DR

This paper estimates the universe's mass by analyzing a test particle's behavior using Newtonian mechanics and a Yukawa scalar field theory, incorporating Hubble's law.

Contribution

It introduces a novel approach by combining Newtonian mechanics and scalar field theory to estimate the universe's mass.

Findings

Estimate of the universe's mass obtained

Comparison between Newtonian and Yukawa models

Insights into the test particle's behavior in cosmological context

Abstract

We make an estimation of the mass of the universe by considering the behavior of a very special test particle when described both by using the Newtonian mechanics as well through a scalar field theory of the Yukawa kind. Naturally, Hubble's law is also taken in account.
