The Physics Teacher
This month's cover depicts a scene from the merging of two black holes and the associated ripples in spacetime. The inset represents the subsequent chirp signal received by LIGO this past September, about a billion years later. See "Ripples in Reality" by Don Lincoln and Amber Stuver for more details about this new window through which to view the universe.
