A glip from Alien Class

I'm not sure if you've all heard about the silliness of Utah State, but one of the few integrated science generals is called 'Intelligent Life in the Universe.' I am currently enrolled in an alien class. Anyway, the first weeks of the class were spent discussing all the early models, theories, and discoveries of the universe. I was intrigued in class by something my Professer discussed, but I'm not sure is actually factual... One Johannes Kepler, (working under Tycho Brahe -- awesome name, I know) was playing around with Brahe's measurements and data, and A- discovered that orbits are elliptical, along with other important shiz, but B- hinted at something really cool that I'm not sure was ever proved (or understood). So I'm likely very wrong about most of this, but you geniusses are here here to correct me. There is/was an important order of shapes, don't know why, but it went Sphere, Pyramid, Cube, and then on to some other cooler words. When you start with a pyramid, enclose it by a sphere(1), enclose that by a cube, enclose that by another sphere(2), then on to other multiple sided objects, each followed by a sphere (3, 4, 5) you then have many spheres all increasing in dimentions. What Kepler discovered, is that the radius of each sphere is porportionally related to the distance between each of the planets in our solar system! He didn't know why, but he was pretty accurate in his measurements of the orbits, and found they matched these spheres he'd been playing with. If true, I really am baffled. Random thang for y'all to research for me.
