Talk:Theory of relativity (view source)
Revision as of 05:45, April 12, 2012
, 05:45, April 12, 2012→Why are adjustments needed to GPS?: The references are hearsay. Logic is far more compelling, more efficient, and more likely to lead to the correct result.
:::::Really? Is it fair to say then that this contention that the synchronization is required as a result of quantum mechanical effects is not something that you have read about but rather something that you yourself concluded from your own knowledge of quantum mechanics and GPS systems? --[[User:JeromeKJ|JeromeKJ]] 00:21, 12 April 2012 (EDT)

:::::P.S. As a result of this discussion I found a couple of articles which appear to confirm that GPS satellites have their clocks adjusted by about 38,000 nanoseconds per day before launch in compliance with relitavistic predictions (both Special and General Relativity are taken into account). The articles are [http://metaresearch.org/cosmology/gps-relativity.asp here] and [http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit5/gps.html here]. Is there really any question that this is what is happening? I would think that if these sources are to be questioned that some sort of reference should be provided. A mere assertion that the adjustments are as a result of quantum mechanical effects and that it is a matter of logic would not usually be enough for any serious encyclopedia. --[[User:JeromeKJ|JeromeKJ]] 00:53, 12 April 2012 (EDT)

::::::To take the analogy mentioned above, if you agree that [[perpetual motion machines]] are impossible, what is the reason?--[[User:Aschlafly|Andy Schlafly]] 01:45, 12 April 2012 (EDT)
