“A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At teh end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever, " said the old lady. "But it turtles all the way down!”

“Anyway.I’m not allowed to watch TV, although I am allowed to rent documentaries that are approved for me, and I can read anything I want. My favorite book is A Brief History of Time, even though I haven’t actually finished it, because the math is incredibly hard and Mom isn’t good at helping me. One of my favorite parts is the beginning of the first chapter, where Stephen Hawking tells about a famous scientist who was giving a lecture about how the earth orbits the sun, and the sun orbits the solar system, and whatever. Then a woman in the back of the room raised her hand and said, “What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.” So the scientist asked her what the tortoise was standing on. And she said, “But it’s turtles all the way down!”I love that story, because it shows how ignorant people can be. And also because I love tortoises.”

“What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.”

“The master was an old Turtle--we used to call him Tortoise--'Why did you call him Tortoise, if he wasn't one?' Alice asked.We called him Tortoise because he taught us,' said the Mock Turtle angrily; 'really you are very dull!'You ought to be ashamed of yourself for asking such a simple question,' added the Gryphon; and then they both sat silent and looked at poor Alice, who felt ready to sink into the earth.”

“And the most interesting natural structure?A giant, two-thousand-mile-long fish in orbit around Jupiter, according to a reliable report in the Weekly World News. The photograph was very convincing, and I'm only surprised that more-reputable journals like New Scientist, or even just The Sun, haven't followed up with more details. We should be told.”

“Their mistake was the mistake of Galileo. He was right that the earth revolves around the sun, but he didn't know that the entire solar system revolves around yet another center; he didn't know that the real orbit of the earth, as opposed to the relative orbit, is by no means some naive circle...”
