Um panorama Histórico-cosmológico da energia escura.

Abstract

In this present work, we aim to carry out a bibliographical review on the dark component of the universe, which is so peculiar, dark energy. we will depart from a historical introduction to cosmology and its current context, as the object of our interest is one of the most sought after in cosmology studies today. IT'S It is important to note that cosmology has been making recent discoveries, such as we can see from the Nobel Prizes in Physics, in 2006, 2011 and 2019. talk about the possibility of there being such an exotic component as energy dark, let's expose which main observational evidences that point to a scenario where there is a need for this component. So we can better understand what dark energy is and what effects it causes to our universe. Finally, we will discuss the most acclaimed dark energy models by the studies that deal with the area, and we will deal in more depth with the ΛCDM (Λcold dark matter) and quintessence models, some alternative models will only be quoted. The ΛCDM model is also called the CDM model. cosmic agreement, not by chance this is the model that best fits the observations and available data. Through our bibliographical research, it is The superiority of the ΛCDM model in the available bibliographies is clear, although present problems such as the problem of fine-tuning and the coincidence.
