Neutrino oscillation directly observed
There has been little doubt that they do oscillate, but still…
One cool thing about this experiment is that neutrinos produced in it are more energetic than those from any known natural sources. It is often erroneously claimed that the LHC will produce “unprecedented, never seen in the Universe energies”. Well, the OPERA experiment has apparently been creating neutrinos of unprecedented energies.
Neutrino is an anagram of “inner out”
