Scientists announced last month that they had recorded the sound of two black holes colliding [3] and merging a billion light-years away. The sound was described as a small, quick, birdlike chirp [4]. Create a list of object pairs; the items can be clearly connected—like a red car and a blue car, or you and a loved one—or disparate, or conceptual. Choose an especially inspiring pair from your list and write a poem about the two objects as they head on a collision course, and the unexpected sound that’s heard when they finally merge.
