Introduction to Astronomy March 2022

Our Universe Is Expanding

How Do We Know?

by Jonathan Park

We know the universe is getting bigger and bigger, which means space itself is expanding – new space is coming into existence. Working backwards from now, we arrive at a time 13.8 billion years ago when the universe was in a hot, dense state. The sudden onset of expansion was the “Big Bang” – not an explosion in space; instead, it was a rapid expansion of spacetime itself. How do we know all this? Astronomy is a science, and in science, we can’t just say something is so, and that’s that. We need evidence and theories that make predictions. Our guest speaker, Jonathan Park,  will show you how astronomers know all of this in March’s Introduction to Astronomy talk.

We look forward to seeing you all on our YouTube website to view this online using the below link.
