Black holes come in many sizes. Small, medium, large & extra large. The size of a black hole mostly depends on how massive the star was before it ran out of fuel, exploded as a supernova and collapsed under its own extreme gravity. The more massive the black hole, the stronger and larger its effect on the fabric of space and time. 

 

Here’s the new bit! In a recent study, astronomers found that even tiny black holes have immense power to shape their part of the galaxy. Far more than previously thought. Black holes can rip apart a star that comes too close by. Even the tiniest black holes, known as stellar-mass black holes can do this.
