In ancient times the earth was said to be a flat slab riding on the back of a turtle and below that more turtles, one upon the other, all the way down. The same is so today, but the scope is the full universe and all its parts, and the turtles are the mathematical and other models created for support and understanding. We remain powerless against its forces, against its origin, passing, future, and even time. In fact, over the past few centuries the corps of turtles have changed abruptly every couple of decades. From Newton's mechanics to Heisenberg's uncertainty, to the current M-theory, the turtle-carriers seems to be changing at an increaing rate.
