Analysis of Five Galaxies with Flat Rotation Curves

Authors: Gene H. Barbee

Flat galaxy rotation curves are unexpected observations. Differences between expectations and observations allow us to learn. Most cosmologists today attribute the difference between observed flat and calculated declining Newtonian velocity curves to dark matter despite decades of failed efforts to identify it. This paper examines data for five galaxies. Physics for flat galaxy velocity curves is proposed that preserves Newtonian gravitation and explains the flat velocity profiles. The proposal shows that a known quantum effect that physicists call spin actually scales to the galactic scale. The calculation procedure is straightforward and matches data. Data for planets in our solar system is discussed. Dark matter is not required in this approach.
