Although the study involved computer simulations and is thus purely theoretical, in practice, the formation and merger of pairs of black holes can give rise to tremendously powerful gravitational radiation — ripples in the fabric of space and time, traveling at the speed of light — that is likely to be visible at the edge of our universe, Reisswig says.
