Quantum physics predicts the universe should’ve collapsed right after the Big Bang, because all particles were immeasurably heavier. Yet it obviously didn’t. Observations confirm this puzzle, and experiments at the Large Hadron Collider still haven’t explained why. At its core is the lightness of the Higgs boson, part of the “hierarchy problem,” which many call physics’ biggest unsolved mystery.
