News is emerging from CERN / Grand Sasso of the results from a three year experiment where neutronos are sent from CERN to Grand Sasso, Italy, 730 km southeast. They think the neutrinos arrive 60ns too early.

Located east of Rome in an Appenine mountain.
Faster than light seems to come into the same category as news about creating a quieter vacuum by avoiding anti-matter intruding, a matter of phase.
Think I’ll go back to tending the roses.

“The OPERA neutrino velocity result and the synchronisation of clocks

(Dated: September 30, 2011)
The CERN-OPERA experiment [1] claims to have measured a one-way speed of neutrinos that is apparently faster than the speed of light c. One-way speed measurements such as these inevitably require a convention for the synchronisation of clocks in non-inertial frames since the Earth is rotating. We argue that the effect of the synchronisation convention is not properly taken into account in the analysis of [1] and may well invalidate their interpretation of superluminal neutrino velocity.”
