In case you haven't figured it out, my nine-year-old son, Bubba, has an interesting way of seeing the world. He comes up with some brilliant thoughts.
Here was today's brilliant thought:
"Mama," he said. "If we could dig a hole to the other side of the earth, would we be able to fall at the speed of light through it, and then continue into space?"
"Bubba," I said. "I don't think you'd fall at the speed of light, but you'd go pretty fast. As far as continuing to space, I think the force of gravity would kick in, and send you back the other way."
He thought about that a second. "That would be cool. Then you could go back and forth bouncing from one side of the Earth to the other. They should invent an amusement park ride like that."
Uh, right. Can you imagine how long you'd have to stand in line to get a turn?
