What primary process triggers a massive star to undergo a supernova?

Answer

The star runs out of fuel and collapses under its own immense gravity

A supernova is the violent conclusion of a massive star's life cycle. Once a star exhausts the nuclear fuel required to maintain its internal pressure, it can no longer counteract the inward pull of its own mass. Gravity takes over, causing the core to collapse rapidly. This gravitational collapse creates an immense release of energy, resulting in a spectacular explosion that scatters stellar material back into the cosmos.
