Astronomers have discovered 33 pairs of merging black holes in cosmic dances around each other, a finding that was predicted or 'choreographed' by Isaac Newton. "These results are significant because we now know that these 'waltzing' black holes are much more common than previously known," said Dr. Julia Comerford of the University of California, Berkeley, at the American Astronomical Society meeting in Washington, DC. "Galaxy mergers are causing the waltzing, can use this finding to determine how often mergers occur. The black holes dancing towards us are shifted towards blue light, and those moving away from us are shifted toward the red. So it is like a cosmic disco ball showing us where the black holes are dancing."
