Last week, physicists at the Large Hadron Collider in Switzerland announced they might have discovered a brand new force of nature. Or, to be precise , they unveiled “new results which, if confirmed, would suggest hints of a violation of the Standard Model of particle physics”.

The Standard Model, devised between the 1950s and 1970s, has been enormously successful at explaining the behaviour of subatomic particles and three of the four fundamental forces we know about. The physicists at CERN think they’ve found a situation that the Standard Model can’t explain: where the model predicts a particle called a beauty quark should decay into other particles called muons and electrons at about the same rate, it looks like it actually decays into electrons more often than muons.

This is exciting, because we already know the Standard Model doesn’t tell the whole story about what’s happening in the universe. It’s very good at telling us about matter and energy. But it doesn’t provide an account of the so-called dark matter and dark energy scientists believe must exist to explain the large-scale behaviour of stars and galaxies.
