Novel Test for Verifying Existence of Dark Matter

Scientists from the University of Bonn and the University of California at Irvine used advanced computer simulations to develop a test that might solve a hot puzzle in astrophysics: does dark matter really exist? Or is there a need for Newton’s gravitational law to be modified? The innovative research, which has now been reported in the Physical Review Letters, demonstrates that the solution is hidden in the motion of the stars inside small satellite galaxies spinning around the Milky Way.
