Sorry, I have no "P'sak" for the Geocentrism-Relativity discussion thread, but I have the next best thing:
1. I compiled the series of posts on P'sak and Rabbi Meiselman's thesis into a single document that can be accessed here: http://goo.gl/Deyrfo. Update: Here is a version with margins that is nicer to look at and can be printed and converted to other formats: http://goo.gl/oEBozN.
- Geocentrism is also a valid frame of reference, but then so is Heliocentrism and every other one: http://blogs.discovermagazine.com/badastronomy/2010/09/14/geocentrism-seriously/
- Geocentrism is not a valid frame of reference, even with relativity, and is just wrong: http://www.talkorigins.org/origins/postmonth/2011_05.html
