Wtf is time?

What exactly is time? We measure it with clocks. We organize our lives around it. We watch it pass, lose it, waste it, and wish we could go back. But what if time isn’t quite what we think it is? In this video, we explore one of the oldest and strangest questions humanity has ever asked: *what is time?* From the philosophical ideas of Heraclitus and Saint Augustine to Newton’s absolute time, from Bergson’s distinction between lived time and measured time to Einstein’s theory of relativity — our understanding of time has changed dramatically. We’ll look at the experiments and ideas that challenged our intuition, discover why time can pass differently for different observers, and explore what physics and philosophy can — and perhaps cannot — tell us about the nature of time. Is time something that exists independently of us? Is the present a real thing? Does the past still exist? And why does time seem to move in only one direction? Maybe the strangest thing about time is that the more we learn about it, the less obvious it becomes. So… what is time? If you enjoyed this video, consider subscribing to **Never Lost Again**.
