Time really slows down. GPS satelites wouldn't have worked if it wasn't taken into account. http://en.wikipedia.org/wiki/Error_analysis_for_the_Global_Position

- mkagenius 11y agoThat is again just the clock going haywire.
- soneil 11y agoIt's the clocks on all 24 GPS satellites, all 24 Glonass satellites, and the 8 (so far) Galileo satellites, all going "haywire" by precisely the amount predicted by a theory developed before the first satellite went into space. And it's not a paltry amount - if we didn't understand and plan for this amount, the GPS system would have an error drift of 10km (~6 miles) per day
