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.
