My little boy is 4 foot, 3 inches tall, and he eats too much candy.

Sometimes, later, when the sky is clear, he'll sneak upstairs past his sleeping parents and look out and up. He will put his eye to the lens of a telescope and peer upwards. There are other worlds than these. He will sit there for hours and notice the time only by the movement of the stars.

Curiouser, he pushes his eye closer to the lens, hoping to see just a little more.

It's the same thing every night. He wants it. He needs it.
