Imagine you’re watching two cars race around a big circle. One car is super fast, and the other one is slower. But here’s the tricky part: the fast car is on a smaller circle inside the big one.
As you watch them, there are times when the super-fast car zips past the slower one. When that happens, it might look like the slower car is going backward, even though it’s not. It’s like a race where the speedy car does a loop and tricks your eyes into thinking the other car is going in reverse.
