.A number of evolutionary paths can cause a supernova surge. One is actually the death of a supermassive star. When a supermassive superstar lacks its own hydrogen fuel, it begins a phase where it fuses the remaining components to much heavier and bigger ones. These ultimate combination responses create less and much less external force (radiation stress) to stabilize the star's gravitational yank incoming. As much heavier aspects develop in the superstar's core, the center on its own begins to fully break down under its personal gravity, and also the celebrity's outer levels blast away in a supernova surge. Depending on the superstar's original mass, its own core might collapse to just neutrons, leaving behind a neutron celebrity, or even its gravitational force may be actually so wonderful that it breaks down to a black hole.
