  Pulsars are spinning neutron stars with very regular periods. These pulsars
have, however, had instances where they exhibit a change in their periods.
Older theories have shown that older pulsars have a tendency to skip and speed
up. Newer theories have been created, due to the discovery that younger X-ray
pulsars exhibit the same skips. The older theories explain that the core of the
pulsar is a superfluid with a differential rotation and the core will
occasionally exhibit solid properties to catch the crust of the pulsar and
speed it up. The newer quantum mechanical theory states that quantum particle
packets, called the strange nuggets, slam into the side of the pulsar to add
angular momentum to the pulsar and then release it later.
