Hoyle triple-α framework: 3 α → ¹²C via A=8 ⁸Be resonance; Q ≈ 7.65 MeV

The Hoyle-state triple-α mechanism — the celebrated Fred Hoyle 1954 anthropic prediction resolving the long-standing 'A=8 bottleneck' in stellar nucleosynthesis. The obstacle: direct 3α → ¹²C requires a simultaneous three-body collision…
