Hubble, Hubble's law and the expanding universe

TL;DR

This paper reviews Hubble's law, its historical development, and its implications for models of the expanding universe, highlighting key discoveries and their significance in cosmology.

Contribution

It provides a comprehensive overview of Hubble's law, connecting historical discoveries with modern cosmological models and understanding of the universe's expansion.

Findings

Hubble's law establishes a linear relation between galaxy recession velocity and distance.

Historical analysis traces the development of ideas leading to Hubble's law.

Discussion of how Hubble's law informs current models of an expanding universe.

Abstract

Hubble's name is associated closely with the idea of an expanding universe as he discovered the relation between the recession velocity and distances of galaxies. Hubble also did a lot of pioneering work on the distribution of galaxies in the universe. In this article we take a look at Hubble's law and discuss how it relates with models of the universe. We also give a historical perspective of the discoveries that led to the Hubble's law.
