Pulsar Cool Fact - Introduction


Pulsars spin fast for the same reason ice skaters pull in their arms to spin. This is conservation of angular momentum. Pulsars are formed with a certain amount of angular momentum. As gravity causes them to shrink (and thus have a smaller radius) they must spin faster in order to conserve angular momentum.
