How do black holes really work britannica
WebThe main light source from a black hole is a structure called an accretion disk. Black holes grow by consuming matter, a process scientists call accretion, and by merging with other black holes. A stellar-mass black hole paired with a star may pull gas from it, and a supermassive black hole does the same from stars that stray too close. WebIt’s possible these black holes began with the collapse of supermassive stars in the early universe, which gave them a head start. While their origins are mysterious, scientists …
