Gravity as the Mechanism

Gravity forces the break. Without gravity, the electromagnetic repulsion wins; two protons never get close enough to fuse, the symmetry holds indefinitely, and there is no break, no energy, no stars, no records, no universe. Gravity compresses matter until the density and temperature overcome the repulsion. This is what AP28 says in abstract — gravity holds all twenty-one channels open. At the core of a star, gravity literally forces two protons through the door. The abstract statement and the physical process are the same statement in different languages.

The hierarchy — the gravitational coupling running ~10⁴⁵ below the electromagnetic in the natural units of the arena (α_G = α_em²¹, up to the geometric factor 1 + 1/π; AP28) — is the structural reason the break is rare. If gravity were as strong as electromagnetism, every pair of protons would fuse immediately; the universe would flash once and go dark. The hierarchy ensures the break happens slowly, in concentrated regions, over billions of years. That is what makes stars possible. The weakness of gravity is not a problem. It is the pacing mechanism that allows the break to produce a universe with structure, complexity, and time.
