How Does The mind-bending physics of time | Sean Carroll Work?

Imagine time is like a toy train track that can go both forward and backward, Sean Carroll helps us see how that works in the real world, not just on the playground.

You know how when you're playing with your blocks, sometimes you build something up, then knock it down? That’s like time moving forward, building, and backward, knocking down. Normally, we think time only moves forward, like a train that just keeps going. But Sean Carroll shows us that in some parts of the universe, time can go both ways, like a toy train that can move left or right on its track.

Just like how your blocks have rules, you stack them one on top of another, the universe has tiny, invisible rules. Scientists use these rules to see why time behaves the way it does. It's kind of like learning how a train works by watching its tracks and how it moves, not just magic, but something real that we can understand.
