Neutrinos travel faster than light - Einstein disproved?

Neutrinos travel faster than light - Einstein disproved? [update]


150 000 sheets of lead, 1,300 tons required for the tau neutrino
detector of the INFN lab
Image: INFN The OPERA experiment, CERN shall, in conjunction with the
Italian INFN Gran Sasso Laboratory has measured neutrino, which move
faster than light, which according to Einstein's special theory of
relativity should not be possible. Already in the pre-accelerator, the
Large Hadron Collider (the Super Proton Synchronotron, PLC) resulting
muon neutrinos were detected in the 730 km distant Italian with 1300
tons of lead shielded laboratory (the muon neutrinos oscillate to tau
neutrinos, the can be detected more easily) and measured the running
time of about 2.4 ms to 10 ns long flight path exactly.

With approximately 15,000 neutrinos the term was 60 ns faster than that
corresponding to the speed of light. In recent months, the researchers
have repeatedly verified the measurement method, but found no errors.
Now they have decided to publish their results. Can check out the the
Fermilab in Illinois, but currently none. Tevatron accelerator which
will now be shut down in late September. The spectacular CERN / INFN
results were also just in time, perhaps to allow a further extension of
the lifetime of the Tevatron.

At 16:00 EST CERN will go down in a live webcast on the discovery, which
may umkrempelt all the physics world - or just, as with so many
"Faster-than-light" reports before, but only a measurement error.

[Update]

For the neutrino production is also sufficient for the small Fermi Lab
accelerator. So even if the Tevatron will shut down, the American
researchers are working on the CERN results to falsify or verify for
just about even.
