The discovery of the Higgs boson was a significant milestone in particle physics, as it helped complete the Standard Model, which describes the fundamental particles and forces in the universe. However, the Standard Model is not a complete theory of particle physics, as it does not account for phenomena such as dark matter or explain the nature of gravity at the quantum level. As a result, physicists continue to explore beyond the Standard Model to deepen our understanding of the fundamental building blocks of the universe.
