In the beginning, there was a Big Bang. After that, well, it gets a little murky. This hour, we're taking you back to the origins of the universe--to the quarks, leptons, bosons and other particles that make up us, and everything around us. We've gathered some of the best minds in cosmology and particle physics to tell us to find out what scientists know about the building blocks of the universe, and what they still need to know. What missing parts of quantum theory can the Large Hadron Collider provide? And where does string theory fit in? In this hour, we'll get an update on the very small--particle physics--and the very large--cosmology--and find out how these two fields of study fit together. Plus, why dark matter doesn't matter here on Earth. We're broadcasting from Tempe, Arizona this week, as part of ASU's Origins Symposium. See a web stream of the Origins Symposium here.
