Videos 1 ARE THERE UNDISCOVERED PRINCIPLES OF NATURE: NEW SYMMETRIES, NEW PHYSICAL LAWS? James Siegrist, Universtiy of California, Berkeley, explains that one of the main goals in particle physics today is to not only discover new particles and forces but also to discover what principles explain their necessity. View the Video 2 HOW CAN WE SOLVE THE MYSTERY OF DARK ENERGY? Rocky Kolb, of Fermilab/University of Chicago, addresses the mystery of dark energy. View the Video 3 ARE THERE EXTRA DIMENSIONS OF SPACE? Joe Lykken, of Fermilab, discusses the exciting possibility of discovering extra dimensions in experiments that are being conducted at particle physics labs right now. View the Video 4 DO ALL THE FORCES BECOME ONE? Jonathan Bagger, of Johns Hopkins University, explains how string theory has the potential to make Einstein's dream of a single grand unified force come true. View the Video 5 WHY ARE THERE SO MANY KINDS OF PARTICLES? The Standard Model provides a description of how particles interact with each other, but John Womersley, of Fermilab, points out that this model doesn't really tell us why the particles actually exist. View the Video 6 WHAT IS DARK MATTER? HOW CAN WE MAKE IT IN THE LABORATORY? Andreas Albrecht, of University of California at Davis, talks about one of the current great mysteries of the universe - dark matter. View the Video 7 WHAT ARE NEUTRINOS TELLING US? Hitoshi Murayama, of Princeton/ University of California, Berkeley, explains how neutrinos can potentially answer questions about how we survived the Big Bang. View the Video 8 HOW DID THE UNIVERSE COME TO BE? Is particle physics in a time of crisis? Keith Baker, of Thomas Jefferson National Accelerator Facility, sees it as a period of opportunity to describe new phenomena. View the Video 9 WHAT HAPPENED TO THE ANTIMATTER? Where has all the antimatter gone? Persis Drell, of Stanford Linear Accelerator Center, explains how answering questions about antimatter may shed light on what happened in the early universe.
