One ancient Greek scientist, Aristarchus, had a theory about the layout of the universe that was quite different from the other Greek theories. According to Aristarchus's theory,

A) Earth is at the center and other objects move around Earth in simple circles. B) the sun is at the center and other objects, including Earth, move around the sun in simple circles. C) Earth is at the center, and the planets move around Earth in orbits that could be described as "circles-within-circles" or "loop-the-loops." D) the Earth is held up by Hercules, who stands on a turtle, who stands on an elephant, who stands on Zeus, who is beginning to think that the whole thing isn't worth the effort. E) there is no fixed center anywhere in the universe.
