We caught up with theoretical physicist Sean Carroll to find out why the discovery of the Higgs Boson was such a major breakthrough and what it means for scientists and our conception of reality. Emphasising the importance of fields in particle physics, Sean explores what's in store next at the Large Hadron Collider and discusses and what exactly physicists mean when they refer to 'symmetry'.
We ask him what could lie beyond the Higgs and if it is worth spending over $10 billion to find out.
Watch Sean Carroll present his talk on 'The Particle at the End of the Universe':
