Finding the Higgs boson, a breakthrough in fundamental science that in 2012-2013 revealed an elementary reality about how the universe works, has highlighted how much more physics needs to be done.
Discovering the Higgs boson plugs a large hole in the standard model, the highly tested theory that shows all matter is made of a number of elementary particles that interact through four fundamental forces—strong, weak, electromagnetic and gravitational forces. Together, these comprise everything we currently understand about matter.
"The standard model provides a consistent explanation of the subatomic world," said Jonathan Bagger, a high-energy physicist who is the incoming director of Canada’s national laboratory for particle and nuclear physics. "The Higgs boson is at the center of the model. It’s the linchpin. But there’s plenty of the universe that the standard model doesn’t address."
