Its existence took place when the core of a supermassive star collapse after which a supernova explosion took place. FORMATION OF A BLACK HOLE To understand the formation of a black hole we need to understand the concept of a star. Nuclear fusion is the process through which a star produces its energy. A star is made up of mostly hydrogen and helium. In its core, nuclear fusion occurs in which hydrogen combines with hydrogen to produce helium. This process continues further and forms more heavy elements like carbon, silicon, magnesium, deuterium, etc. Iron is also formed in the core which can be referred to as the murderer of the star. The problem with iron is th...
