I have wondered this for a while now, what stops large elliptical galaxies from collapsing due to their gravity?
Their rotational speed is relatively small, at the rotational axis perhaps zero, so what is preventing the stars from being pulled towards the center? Do spherical ellipticals flatten with time?
