Aussie Boy,
The science of today is diffrent then the science of old. For example the Rambam (and just about evreybody else who lived in his time) beleived that the planets were all attached to hard clear spheres which turned and upon which the planets turned also.
This theory explained the motion of the planets as they saw them and was excepted as fact for hundreds of years.
That theory has now been disproven beyond any shadow of a doubt by modern science because we have sent satalites up past the orbits of evrey planet in the solar system and they havnt crashed into any hard spheres. There is no chance that we will one day discover that the theory that the Rambam thought was correct (hard clear spheres) is correct.
