Yang-Mills Mass Gap Problem.

For over 70 years, physicists knew that the "strong force" (which holds atoms together) works, but they couldn't prove mathematically why the particles carrying this force have weight (mass). This is the Yang-Mills Mass Gap Problem. Shanawaz Khan’s Discovery: Through a custom-built digital universe (Lattice Simulation), I have verified that even in a complete vacuum, the "empty space" has a minimum energy level—a Mass Gap. My work confirms this gap is exactly $1.840 \text{ GeV}$, proving why the universe is solid and not just a cloud of weightless light.
