During the collapse of a massive star,the core will rebound outward in a process called core bounce.What causes this phenomenon?

Question

Quizplus · Accepted Answer

As the core of a massive star collapses, it reaches a point where the density of the matter is so high that it becomes as dense as nuclear matter. This causes the core to stiffen and resist further collapse, leading to a rebound and the process known as core bounce. This energy is then released in the form of a supernova explosion. Neutrinos are also released, but they do not play a significant role in causing core bounce. Gamma rays and radioactivity are also not responsible for core bounce.
