The Nature of Time

Time is a complex concept that blends seamlessly with our existence yet remains elusive and difficult to define. Theoretical physicist Marcelo Gleiser emphasizes that while we can measure time with operational definitions, its true nature and essence are still beyond our grasp. He suggests that perhaps time is a human construct designed to make sense of our lives, indicating that we need it primarily when we are narrating change or a story. Without change, time becomes irrelevant, reinforcing the idea that stories of the universe are inherently tied to the passage of time.
