What is Time? Tackle one of the greatest problems in all of science—the nature of time itself—in “Mysteries of Modern Physics: Time,” a groundbreaking course by Dr. Sean Carroll, one of the foremost researchers in this field. In this second video from the 24-video series, Professor Carroll approaches time from a philosophical perspective. “Presentism” holds that the past and future are not real; only the present moment is real. However, the laws of physics appear to support “eternalism”—the view that all of the moments in the history of the universe are equally real.
