Starts With A Bang #2 - Size Of The Universe

Although it's been only 13.8 billion years since the Big Bang, we can see objects as distant as 46.1 billion light years away. How is this possible? Ethan Siegel explains in the second Starts With A Bang podcast. Plus, how to see Comet Catalina in the December skies, and why it's on its way out of the Solar System forever.
