　"Imagine that you have captured Wonder Woman's invisible airplane. You can't see it. But you know it's there because when you throw a rubber ball at the space, the ball bounces back to you. If you could throw enough rubber balls, from all different sides, and measure their trajectory and speed as they bounced back, you could probably get a pretty good idea of the shape of the plane."
