The discovery of a new sub-atomic particle is being described as "momentous" and a true milestone. Scientists believe it is the long-sought Higgs boson – sometimes called the "God particle" – which gives matter mass and holds the physical fabric of the universe together. Host Marco Werman challenges The World's Science Editor David Baron to explain just what the Higgs boson is and why it's considered so important. Marco then speaks with physicist Jordan Nash of Imperial College London, a member of one of the teams that found the particle, about what comes next.
