thread_title: New Citation Needed

message: From the article:
The ideas of a flat earth, Counter-Earth, and Central Fire were all eventually superseded by the theory which is currently held by the scientific community, that is, of a spherical earth rotating around its own axis while revolving around the sun.
I'm afraid that my knowledge of astrology is somewhat limited but I was of the impression that the notion of the earth being spherical and rotating on its own axis while orbiting the sun was a universally excepted fact. Was I mistaken? --86.171.204.147 (talk) 18:33, 7 April 2009 (UTC)
thread_title: Theory?

message: I've been contemplating whether or not to bring Central Fire into this article, but that would necessitate changing this article's title, and I don't know what to change it to. Serendipodous 15:08, 31 March 2010 (UTC)

thread_title: Merge with [[Central Fire]]?

message: Furthermore, since none of the other planets has such a twin it would be extremely improbable if the Earth were the only planet to have one.
This sounds like "Since none of the other planets has a wikipedia, it would be extremely improbable if the Earth were the only planet to have one." It should be rewritten. Earth is quite improbable. -- Error
:More like, "Since all of the other planets have gravity it would be extremely improbable if the Earth were the only planet not to have it." Some things are more improbable than others. --Lee M
Back to the article, is it true that the astronomical counter-earth was invented to save the phonomonea that the central fire could not be seen, a central tenet in pythoragean thought. (windsor ppt presentation--I am not a windsor student and do not feel comfortable putting this in--but seems like a definition of counter-earth should dominate this article. --Sam
Yes, the whole idea of a Counter-Earth was developed by Philolaus to support his new ideas about the non-geocentric cosmos and a Central Fire. You can learn more about this here. Mrwuggs 20:56, 7 November 2006 (UTC)

*Support -- I realize now that a copy and paste merger is the wrong way to merge things, but seriously, there is no reason why this should be two pages. Although the copy/paste job was improperly done, that was just the way this article should look. This page seems ideal for a speedy merger. Mrwuggs 19:40, 28 September 2006 (UTC)

message: The information about Mela's spherical Counter-Earth is, at least in my opinion, probably better situated in the "Need for a Counter-Earth" section than in the "Scientific Analysis" part. Galanskov 23:44, 23 November 2006 (UTC)
thread_title: Wrong Section

message: The diagram is currently marked as needing conversion to a vector format.  If that's done, it would only make sense to correct any other outstanding issues with the current diagram.  However, I'm a bit puzzled by several features:
:#The current diagram shows Antichthon on a different orbit from Earth, with half the orbital radius.  Why not the same orbit?  The article doesn't seem to mention this.
:#The current diagram shows the Earth and Antichthon as spherical, and indeed, the article text notes that the understanding of a spherical Earth was one of the central facts in the chain of reasoning that led to the Antichthon idea.  However, it later describes Earth and Antichthon as "flat."  How is this to be reconciled?  If the diagram were to change the shape of Earth and Antichthon, exactly how should they be represented?  Hemispheres, disks, cylinders,...?

message: The celestial mechanics of a counter-Earth (anti-Earth) were done numerically by the US Naval Observatory for the Condon Report 1968 Scientific Study of Unidentified Flying Objects.

thread_title:  USNO Numerical Experiment 

message: The article is a bit confusing in that it starts by saying that in the 5th Century BC everyone accepted that the world was spherical - that Philolaus set out to solve problems arising from this - and that in doing so he proposed that the earth was flat. In postulating a flat earth, didn't he undermine the very problem he was addressing?  —Preceding unsigned comment added by 141.241.199.124 (talk) 12:54, 24 August 2009 (UTC)

message: I'm working on an article for Pythagorean astronomical system. Seems a bit silly to have an article on one body in this theory (the counter-earth) but not on the overall theory.
