I have explained in my pre-print THEORY OF UNIVERSALITY the concept of Dark Matter being the matter resulting out of the energy outpouring of the stars. Moreover, the absolute speeds of Dark Matter and Black hole are less than speed of light. It is also derived that the various star and planetary systems are having absolute speeds greater than that of light as observed by an observer placed outside the universe imaginably. Please, refer the pre-print THEORY OF UNIVERSALITY .

The age of Sun was calculated to be 4.4491 billion years ( came close to observed value of 4.5 billion years ) by taking that Sun was a small bubble-like particle jetting out of the black hole at speeds billions of times greater than the speed of light.
