Venture deep inside the world’s biggest physics machine, the Large Hadron Collider. This extraordinary feat of human engineering took 16 years and $10 billion to build, and recently began colliding particles at energies unseen since a fraction of a second after the big bang. We’ll explore this amazing apparatus that could soon reveal clues about nature’s fundamental laws and even the origin of the universe itself. John Hockenberry moderates a discussion among physicists including Marcela Carena, Monica Dunford, Jennifer Klay, and Nobel laureate Frank Wilczek.
