Nucleons (protons and neutrons) are the building blocks of visible matter, and comprehending their mass and spin structures, governed by massless gluons, stands as one of the grand challenges in explaining the origin of ~99% of the visible universe's mass and its stability. Simultaneously, the very existence of our visible universe is tied to the currently unexplained predominance of matter over antimatter, a mystery that physics of nearly massless neutrinos may unravel. I will discuss how first-principles lattice QCD calculations can help address these fundamental questions in physics.
