Infinite obesity They are established at the core of almost every galaxy,

gulping, swallowing and devouring everything that happens to be in the domain of their gravity (event horizon). These cool and dark objects can sometimes pull the outer surface of gases from stars to form an accretion disc around them. Merging of two black holes, swallowing up of stars, universal gases and dust contribute to its increasing mass. Stellar-mass black holes can eventually become supermassive ones. Although these themselves refrain from growing infinitely by emitting enormous energy at the same time, ultramassive black holes can keep on growing given their extremely gargantuan size.
