Oct 24 at 15:33 | comment | added | KierD | The mass of dark matter required for galaxys to be stable is of comparable order of the mass of the regular matter in the galaxy. When you compare the equivalent mass of this rotational energy to the mass of the Milky way, it comes short by a few orders of magnitude | |
