I am an undergraduate physics student at METU.
In the cosmology section of the Physics Forums, I encountered many Big Bang and related infinity problems. Hence, in this article, I want to explain the Big Bang, the topology of the Universe, and the concepts of singularities and infinities. First, let’s start with the concept of the observable universe and what we mean by…
Previous Chapter: A Journey Into the Cosmos – The Friedmann Equation Chapter 2- FLRW Metric and The Friedmann Equation In this chapter, we will further investigate the Friedmann equation and we will explore the FLRW metric. We will solve the Friedmann equation for three different types of models (matter-dominated, radiation-dominated,…
This is an introduction to cosmology for someone who has some knowledge of calculus and basic physics. In this tutorial, we will take a journey into the cosmos to study cornerstone ideas in cosmology and their derivations. Let’s begin our journey, by explaining the meaning of cosmology. Cosmology is the study of the origin, evolution,…
