The LHC won't destroy the planet (but will spark a revolution)

Professor Jesse Thaler discusses how the Large Hadron Collider will not destroy the world. It will, however, revolutionize fundamental physics by providing insights into the origin of mass, the nature of dark matter, the apparent weakness of gravity, and the symmetry structure of our universe.

This lecture explains the scientific basis for particle physicists' confidence, both in the discovery potential of the LHC and in its absolute safety.
