It is important to remember why a theory is accepted by scientists. A particular theory is accepted over other theories on several grounds. 1. The theory fits known facts as well as or better than competing theories. 2. The theory provides an explanation of known facts or observations that is simpler or more consistent than the explanation provided by other theories. 3. The theory accurately predicts as-yet unobserved facts or behavior which are subsequently observed. One reason the idea of an earth-centered universe is not generally accepted by scientists is because there are simpler theories that fit the facts. It may be possible to construct physical laws which allow an earth centered universe (I don't know enough about physics or astronomy to argue on this point) there are simpler explanations which fit the existing fabric of physics. If some additional fact came up that invalidated the current set of laws that govern physics and astronomy, or if some additional useful prediction could be made on the basis of an earth centered universe, you can bet that the idea would receive more than casual scrutiny from scientists. Astrology is not well accepted as a science because it fails in all respects. Astrology does not, on average do a better job of predicting the future than you could do by guessing based on what you know about the world. Astrology does not provide an explanation of its own workings at any more detailed level than "the influence of the planets." Why planets should have particular influences is not even addressed, yet the influences are postulated. Since astrology does not attempt to explain anything, it is also freed from the requirement of being consistent with any facts. Remember, scientists are curious people. They will look at theories with which they disagree, if only to reassure themselves that they are right. Any theory which is simple, consistent, explains known facts well, and has a record of predicting hitherto unknown phenomena will gain a following of scientists.
