According to hypothesis of DM, it is concentrated near to galaxy, holds stars inside the galaxy. But I think that stars aren't holded there. They moving around the center of galaxy and out, their velocity slowly increasing due to gravity of far galaxies. Calculation is simple, it is based on known mass and size of Universe. But, to get expecting result, we have to take in account dynamical nature of gravity. Edited August 25 by kba
