Temperature is the vacuum's energy — from absolute zero (a dead vacuum), through the CMB (2.7 K, default) faint red glow, up to the Planck temperature (~10³² K). Heating blues the photons and — once kT nears a rest energy — pairs erupt from the vacuum (e⁺e⁻ ≈10¹⁰ K, then μ⁺μ⁻, then p p̄ — every hadron is already a quantum black hole). Near the Planck top, micro black holes form (Compton = Schwarzschild) and Hawking-evaporate. Or inject a pair yourself. Bodies drift down the latency gradient (no forces), so a free p + e recombine into H (a photon flies off), two H bond into H₂, and H + H̄ annihilate — bound states are generated by the dynamics.
