No faster-than-light neutrinos? Darn.

Well, the experiment that appeared to show a beam of neutrinos traveling faster than light appears to be a goof. The CERN researchers who made the claim may not have properly taken into account the motion of the GPS satellites providing the timing signal that seemed to show neutrinos being detected .64 nanoseconds too fast for normal travel between the transmitted in Switzerland and the receiver in Italy.
COMMENT #1 - most people don't realize that GPS satellites don't just provide location. The GPS constellation also provides the world's most accurate timing information, used by scientists, militaries, etc. worldwide.
COMMENT #2 - This article headlines that she shouldn't fire up our faster-than-light (FTL) spaceship drives just yet. True, but it's another opportunity to point out that a vigorous community of talented scientists and engineers are looking at how we can realistically achieve interstellar travel with spacecraft moving at up to half lightspeed.
