What are the Different Types of Black Holes?
Black holes are points in space with so much gravitational pull that not even light cannot escape from them. The “point of no going back” around a black hole is referred to as its event horizon. Black holes are formed either when a star greater than 20 solar masses collapses, or when the entire core of a galaxy collapses. Galaxy-collapse black holes release tremendous amounts of energy which can be observed from billions of light years away. This energy comes from the friction of infalling matter against itself — no radiation can emanate from the black hole itself. Black holes are among the most intriguing astrophysical phenomena in the universe. They have captured the imagination of the public and dedicated study by many famous physicists, including Albert Einstein and Stephen Hawking. Black holes are interesting from the perspective of physicists because they can be characterized exhaustively by only three values: their mass, rotation, and charge. Slightly different theories are used
