Galaxies Don’t Spin The Way You Think

galaxy is a gravitationally bound system of starsstellar remnantsinterstellar gasdust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally « milky », a reference to the Milky Way. Galaxies range in size from dwarfs with just a few hundred million (108) stars to giants with one hundred trillion (1014) stars, each orbiting its galaxy’s center of mass.

Galaxies are not spinning tops. So how do stars move within them?
