Fine .. then why did you bother asking .. he's addressed it Sagnac is perfectly explained and predicted by SR.

Why didn't you refer to some of them instead of demonstrating your zombie reasoning? See this for instance: http://www.newtonphysics.on.ca/faq/invalidation.html Find the mistake Andersen Andersen!

If it says the SR doesn't account for Sagnac, then there must be a mistake, because it is an experiment that support and whose result is predicted by SR. But you're just too blind and stupid to understand the facts.

You say this over and over but wheres your proof? Have you tried an accuarate mathematical simulation to back up this claim you make? No. The fact is I have, using vector calculations and posted them as sagnac sims at... http://www.youtube.com/profile?user=jaymoseleygrb And these show that as long as you calculate in the source frame with the speed as c in the source frame one gets a path difference which is whats observed. You can keep repeating your claim that this doesnt work but if you dont bother double checking by doing your own calculations in the source frame then all your claims are unsubstantiated And erroneous. Not to mention the fact that your own explanation relies on wave particle duality which itself needs magic to explain how the photon switches from particle to wave. Sean www.gammarayburst.com |
