We have often been told that the reason time slows down and mass increases the nearer you approach the speed of light is because it allows the universe to be consistent in different frames of reference. But what is actually going on?

It’s all relative: superluminal neutrino discovery explainedwattsupwiththat.com/2011/10/15/its-all-relative-superluminal-neutrino-discovery-explained/Not so fast little neutrinos. Turns out that the discovery of superluminal or faster-than-light (FTL) neutrinos at CERN has been “explained”. Before reading the explanation, here’s a tidbit of information that would have probably tipped off a lot of skeptics from the start: to measure the “speed” of the neutrinos from point A to point B, the scientists used our constellation of GPS satellites in earth orbit. Turns out Einstein’s theory of relativity comes in handy to explain those missing 60 nanoseconds over 730 km distance… I won’t spoil the explanation any further: from an open source Physics journal: Faster-than-Light Neutrino Puzzle Claimed Solved by Special Relativity www.technologyreview.com/blog/arxiv/27260/— somehow I’m betting the real explanation is still out there… from Anthony Watts

I see that the article states that they could only locate the Gran Sasso lab to within 20 cm and that would introduce an error of about 7ns
Then we have the various inbuilt error margins of GPS location anyway, but they must have corrected for that somehow (I wonder how?)

It's difficult to comment until the boffins have really sorted it out and this debate seems due to rage on. Watch this space.
