Revision as of 20:00, April 13, 2012
, 20:00, April 13, 2012→Why are adjustments needed to GPS?: no credible alternatives proposed to relativity
::In the summary I was careful to stick to facts supported by evidence, and to avoid saying "GPS is dependent on Einstein's conception of space and time", even though the two main references I have quoted do in fact say this. All I said was that the adjustment calculated according to relativity agrees with the actual adjustment, from which one might reasonably conclude, in this instance at least, that relativity is consistent with reality.

::I note that no one has proposed any credible alternative theory as to why the orbiting clocks tick at a different speed from surface clocks, so until some better theory comes along I'm quite happy to stick with relativity. [[User:RolandPlankton|RolandPlankton]] 16:00, 13 April 2012 (EDT)
