How large is the universe? Where does it begin and end? And how does it expand? These are some of the biggest questions of astronomy. And while humanity is so small that we may never be able to fully understand the true scale of the universe, advancements in technology are helping us to look ever-deeper into the wilds of our existence- towards the edge of our observable universe, known as the Cosmic Horizon. Today, we will analyse the universe, its laws, and its awe-inspiring scale.
