We normally think of the Universe as being made up of the same things our Solar System is made up of: protons, neutrons, electrons and light. But when we look out at the Universe on the largest scales, it tells us a different story. In this talk, I'll talk about three key observations in the study of the large-scale Universe—distant supernovae, the Cosmic Microwave Background, and the clustering of galaxies—to show how we arrived at a Universe where the normal matter that makes up everything we know is less that 5% of what's out there. Dark matter and dark energy also play a heavy role in our Universe, and a discussion of that will ensue.
