Galaxies, like hurricanes, are storms.
(Recognizable by their diffuse spiral composition,)
But, instead of being comprized by watervapor
(and water drops) they are comprized of stars.
The number of waterdrops comprizing a huricane is
somewhat similar to the number of stars comprizing a galaxy.
As with the eye of a storm, the center of a galaxy is void.
