Talk:Galileo Galilei

Does my memory fail me - I thought that solar-centrism was scientifically around before G G. SJG^sjg 03:15, 20 September 2007 (EDT)

Sure, the theoretical basis was laid by Copernicus in the first half of the 16th century, and he in turn built on ideas by a couple of other late medieval natural philosophers. Galilei's importance is rather in presenting the first scientific evidence for the Copernican model, through his telescope observations of Jupiter. Also, it's not entirely correct as the article says that he ended belief in geocentrism, since the modified geocentric system proposed by Tycho Brahe was around for about another century, until... sometime in the first half of the 18th century, as I recall. --AKjeldsen^Godspeed! 06:35, 20 September 2007 (EDT)

My understanding is that he stood out for being willing to stand up for heliocentrism. It certainly wasn't his idea. PoorEd 22:19, 25 February 2008 (EST)

The concept that the Earth revolves around the Sun is Copernican. Galileo was a prominent astronomer who risked his life and career by supporting the Copernican model of the solar system. Bizarro Ed^{Alternate Realities} 13:41, 18 March 2008 (EDT)
