Articles like this make me wonder whether the shape of a galaxy reflects the influences (gravity, spin, active\/inactive) of the central black hole or lack thereof. Maybe a black hole with a mass and spin (moment of inertia) above a certain threshold causes a galaxy to become more spiral. Maybe if it spins with a wobble, the spiral develops a central bar. Maybe if the black hole has a moment of inertia that is below a certain threshold in proportion to the rest if the galaxy’s mass, the galaxy becomes elliptical.<\/p>\n\n\n\n

Thoughts return to the weird relationship between the surface area of the black hole’s event horizon (not an existent, since “it” has no energy) to its entropy. Since entropy is a measure of information, the black hole behaves like a hologram. It again leads one to wonder whether the shape of the galaxy is a reflection of the information that is contained in the black hole.<\/p>\n","protected":false},"excerpt":{"rendered":"
