The Cosmic Scale

How large is the universe? Where does it begin and end? 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 universe's true scale, advancements in technology are helping us to look ever-deeper into space, towards the edge of our observable universe known as the Cosmic Horizon. Today, we will get to know our universe, its laws, and its awe-inspiring scale above all.
