P1 1 Could the Sun Survive without Quantum Mechanics?

Abstract

This paper explores the conditions required for proton-proton fusion to occur in the Sun without

the aid of quantum mechanics. It is found that the Sun in its current form could not sustain fusion

without quantum tunnelling, and for it to do so, it would need to be at a minimum temperature

of approximately T = 2.8 × 10⁹ K, a temperature only seen in the most violent cosmic events such

as supernovae and neutron star mergers.
