TED: Gian Giudice: Why our universe might exist on a knife-edge - Gian Giudice (2013)

Summary: The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all atomic matter? With wit and charm, Giudice outlines a grim fate -- and why we shouldn't start worrying just yet. (Filmed at TEDxCERN.)
