NOTHING to do with a Hollywood film-making process, technicolour takes us back to the beginning of the universe, when two of the fundamental forces of nature, electromagnetism and the weak force (which governs particle decay within the atomic nucleus), were united in a single force – the electroweak force. When the universe cooled, the forces split apart. The two seem very different today: photons, carriers of electromagnetism, are massless, while W and Z particles, carriers of the weak force, have mass. But why?
To explain how the Ws and Zs got mass, physicists proposed something called the Higgs – a quantum…
