For those of you that don't know he was the first to see Jupiters moons in a rudimentary telescope. The dogma then was that everything revolved about the Earth on glass spheres. This proved we were special and at the center of the Universe and gods own children etc.

So how could objects revolve around a planet on these perfect glass spheres?

Their cosmology was intrinsically tied to their religion. That leads to closed minds and a path to ignorance.

I am sure that my own level of science will seem just as ignorant to future generations. But at least I don't torture my students if they do not believe me.
