How are black holes created?

Black holes are created in the aftermath of a star's death or a supernova. While scientists may never know what lies inside black holes due to their immense gravitational pull that swallows everything crossing their path, they do understand their origin. These cosmic entities form when massive stars reach the end of their lifecycle and collapse catastrophically in supernova events. The gravitational force in black holes is so strong that nothing, not even light, can escape once it crosses the event horizon, making their interior a complete mystery to science.
