Supernova

Supernova explained in an easy to understand way:

Imagine you're trying to hold onto a large stack of boxes while climbing a staircase, but eventually, you lose your balance, and the boxes come crashing down in a spectacular mess. This chaotic scene is similar to a supernova, where a massive supergiant star can no longer support the immense pressure of its own gravity and collapses. Just as the stack of boxes becomes unstable and falls apart, the star's core succumbs to gravitational forces, leading to a dramatic explosion that we see as a bright supernova in the sky.
