Dear Humans,

A shadow–a normal, everyday thing. A thing that has been following you around since you’ve been around. A thing so ever present that you probably stopped paying attention to it a long time ago.

And yet that humble shadow can help reveal deep truths about our planet, our solar system, and even the entire universe. It shows us that giant galactic bodies millions of miles away are locked in an intricate and rhythmic dance. And we’re just passengers.

But we’re passengers who have a map and schedule, and we know our destination and when we’ll arrive. And it’s all because we cast the shadows, and because we have a human mind that is primed to notice the world around us and make sense of it.

Because we’re small and insignificant, we can’t always see the whole truth. But we can see its shadows. And from that we can start to figure it out.

Sincerely,

Mr. Curt
