http://users.clas.ufl.edu/ufhatch/pa...CHO2-WSYS.html "One of the principal advantages, not celebrated in practice until after Tycho's death, is that the model accounts for the change of phases (the apparent illumination, similar to earth's moon) undergone by Mercury and Venus. The fact is, these two inferior planets go through phases (most notably Venus) ranging from a nearly perfect full disk to a thin large crescent shape. That the Tychonic Model could account (indeed would predict) such changes, notably in the wake of Galileo's telescopic discoveries, proved a very strong attraction. These changes of phase could not be accounted for in the Ptolemaic Model, which assumed that Mercury and Venus moved on circles on a line between the earth and Sun, hence, they could not be imagined to go through phase. In Tycho's Model, as in the Copernican, Mercury and Venus were understood to revolve around the Sun and, hence, they would go through phases like the earth's moon." La vremea lui, a fost un model genial, pe cand modelul heliocentrist era mai prost decat cel al lui Ptolemeu vechi de aproape 2000 de ani. ![]() |

Fiindca asa spune un mit primitv, asezat la inceptul unei carti sfinte pentru trei religii monoteiste abrahamice (de fapt, patru, daca socotim si rastafarianismul). Geocentristii si alti distrusi au in cap doar exacerbarea si fanatizarea cosmologiei religioase aacestor sisteme; ei stiu doar un lucru: cenu poti vedea cu ochii, fie nu exista, fie nu te intereseaza.

Pentru ca daca ar fi fost orbite circulare, modelul necesita mai multe bucle decat modelul lui Ptolemeu. Pare simplu cand il privesti asa dar in realitate este mai complicat decat este cel din antichitate.

In fact, Copernicus was forced to use more epicycles than Ptolemy, i.e. a more complicated system of circles on circles. Thus, Copernicus' model would have failed our modern criteria that a scientific model be as simple as possible (Occam's Razor)." Citat:
