A supernova's incomprehensively large energy release stems mainly from
A) thermonuclear reactions.
B) the gravitational energy released by the core and outer layers.
C) the electromagnetic interactions.
D) the weak nuclear force.

Question

Quizplus · Accepted Answer

The energy release in a supernova primarily comes from the gravitational potential energy of the collapsing core and outer layers, causing fusion of heavier elements, production of high-energy neutrinos, shockwaves, and intense radiation. While thermonuclear reactions and electromagnetic interactions also play a role, they are not the main source of energy release in a supernova. Weak nuclear force is involved in the fusion reactions, but it is not the source of the energy release.
