#497 – Biggest Mysteries in Physics: Antimatter, Dark Energy & ToE – Don Lincoln

The history of physics functions as a centuries-long quest for unification, beginning with Newton’s synthesis of terrestrial and celestial gravity and progressing through Maxwell’s electromagnetism and Einstein’s space-time geometry. Particle physics continues this trajectory by exploring the Standard Model, which identifies fundamental building blocks and forces, including the Higgs field responsible for endowing particles with mass. Beyond these frameworks, the universe presents profound mysteries, specifically the nature of dark matter and dark energy, which remain empirically elusive despite their dominance in the cosmic energy budget. While theoretical candidates like string theory offer potential pathways toward a Theory of Everything, they currently lack the experimental validation required to confirm their validity. Advancing this field necessitates a rigorous, iterative process of empirical measurement, as demonstrated by the discovery of the Higgs boson and the ongoing search for baryogenesis mechanisms.
