I was watching a program on dark matter and how galaxy spin was used to deduce the existence of dark matter. The thought occurred to me if the rate of galaxy spin has been measured on many galaxies and how does the spin differ if it does. Another question arose are there any galaxies with identical spin? Also if there are galaxies with identical spin rates are the galaxies connected with an Einstein-Rosen wormhole?
