Tensão de Hubble e suas implicações.

Abstract

Cosmology is a science that deals with questions that have long been of interest to humanity. It seeks to understand the universe by trying to find clues that reveal data about its origin, structure, and evolution, thus arriving at a more precise cosmological model. Currently, the most accepted model, the Lambda-Cold Dark Matter model, considers that our universe evolved from a state of high temperature and density and is in a process of expansion, with the parameter measuring the rate of expansion known as the Hubble constant. The Hubble constant can be determined in various ways, but in recent years, data measured through different techniques have been presenting different values, leading to what is known as the Hubble tension. In this regard, in the present work, we aim to study, through a literature review, the methods and experimental data for obtaining the Hubble constant, making clear the tension generated by the divergence of the values obtained in its measurement.
