When a neutron star spins very fast, you get a pulsar, which emanates radiowaves that we can detect with radio telescopes. When these tiny mountains collapse, the moment of inertia changes and the star spins a tiny bit faster. In the radio emanations, the timing of the pulsar very suddenly shifts, and we call those &quot;glitches&quot;. https://arxiv.org/abs/1806.01521 Pulsars can spin very fast, and aggregate in big globular clusters, which are thought to be the remenant cores of old galaxies that were captured by our galaxy.
