And then the earth, the world, the planet, the galaxy, and the entire solar system went crazy.

Charles Wallace and the unicorn moved through the time-spinning reaches of a far glazy, and he realized that the galaxy itself was part of a mighty orchestra, and each star and planet within the galaxy added its own instrument to the music of the spheres. As long as the ancient harmonies were sung, the universe would not entirely lose its joy.

Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.

The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.

There's as many atoms in a single molecule of your DNA as there are stars in the typical galaxy. We are, each of us, a little universe.
