I wondered if this book might be a good one for my brother's kids. So I looked on YouTube and found a boy, Benjamin, reading the book to Ellie, a girl with a different last name. Apparently Benamin has a bit of help with video production. It's more sophisticated than a child would do. He reads other books on YouTube as well.
Back on Instapundit, MSO remarks in comments that the bodies of the solar system have motion of exquisite complexity. He goes on further about science fiction writers and time travel. He shows this video depicting the sun moving so fast that the movement of sun and planets are described more accurately as a vortex.
