The standard model and the Lambda-CDM model

The standard model of physics, namely the framework of mathematical laws at the foundation of modern physics, has reigned supreme since the 1970, having been confirmed in countless exacting experimental tests. Perhaps its greatest success was the prediction of the Higgs boson, which was experimentally discovered in 2012, nearly 50 years after it was first predicted.

One application of the standard model, together with general relativity, is the Lambda Cold Dark Matter model (often abbreviated Lambda-CDM or Λ-CDM), which governs the evolution of the entire universe from the
