What is the standard model?

The standard model is a 'catalogue' of subatomic particles (the smallest building blocks of everything in the universe). It categorises these subatomic particles based on their properties and has predicted the existence of particles that were undiscovered at the time - such as the Higg's Boson, which was discovered in 2012.
