And the way Mars has different phases of the sun showed that we had to be between Mars and Venus. As far as I know, Mars doesn't have any phases when viewed from Earth. Actually Mars does display a slight change depending on the viewing angle between it and earth, in relation to the sun. This site has a good example of how Mars sometimes appears gibbous when observed. www.gatesscience.info/teamescience/marsphase.htm |

Eeeh, not quite. He was told that he had to give equal precidence to both theories, though he then went on to write a book in which he basically ridiculed the geocentric theory and made the believers in it look bumbling and inept. The Pope took exception to that. Especially since the stupidest-seeming character in the book was apparently quite obviously (to contemporary eyes) based on the Pope of the time. |
