Dr. Bouw said:
It is generally believed, without evidence, that in the geocentric model the sun, moon, planets, and distant stars all orbit the earth once per day. There is no orbiting involved. What is happening is that the firmament is rotating. Now the nature of the firmament is such that it defines all the physics of the universe, both the local and the universal, protophysics (Chapter 11, page 116). This means that all the “laws” of physics are part and parcel of the firmament and that the firmament acts like a medium for the laws of science. So it is that in a geocentric model the sun, moon, and stars do not gravitationally orbit the earth daily any more than that a molecule in a top gravitationally orbits the center of the top. In the case of the spinning top it is the fibers and material of the top which carry the molecules around the axis of the top. By the same token, in the geocentric model it is the fabric of the firmament which carries the universe about it. A second common misconception is related to the first and that is that the geocentric universe requires that the sun orbit the earth once per year. Again, this is not the case. In a geocentric universe Newton’s (or Einstein’s) laws must be fulfilled just as in a heliocentric universe. Newton’s law of gravity states that from the sun’s perspective, the earth must be seen to revolve about it once per year. It matters not to the sun whether the earth actually does so or appears to do so; remember that we are talking about relative motion, not absolute. If the firmament were to possess a wobble (about which we will say later) which carries the sun, planets, and stars about the earth once a year in such a way that the earth seems to describe an orbit around the sun, then the sun and the universe are content that the law of gravity is being satisfied. Remember, the physics of the universe which specify the law of gravity is fastened to the firmament, not the earth or sun.
