What is the significance of the Higgs boson in modern physics?.

The Higgs boson, discovered in 2012 at CERN's Large Hadron Collider, is pivotal in particle physics as it validates the Standard Model. It provides insight into how elementary particles gain mass through the Higgs field, a fundamental aspect that supports the structure of the universe. This particle's discovery not only affirmed theoretical predictions but also opened new avenues for research into unexplained phenomena like dark matter and the early universe. Understanding the Higgs boson can lead to breakthroughs in physics, potentially unveiling new physics beyond the Standard Model.
