Scientific American reporter Clara Moskowitz spotlights a new study by Prof. Seth Lloyd that explores the feasibility of black holes sending information back in time. In the study, Lloyd and his colleagues calculate how much information can be sent backward via closed timelike curves, intensely bending, rotating space found around spinning black holes. “Spacetime can curve around so much that you can be innocently going forward in time and then you meet yourself in the past,” says Lloyd.
