New Experiments Show Neutrinos Not FTL

New experiments in timing neutrino transmissions seem to confirm that the earlier OPERA measurements were mistaken.
The scientists use the same short pulsed beam from September’s experiment to conduct the ICARUS experiment. CERN’s press release states that the new measurement “is at odds with the initial measurement reported by OPERA last September.”

“The evidence is beginning to point towards the OPERA result being an artefact of the measurement,” said CERN Research Director Sergio Bertolucci, in a press release, adding that “it’s important to be rigorous, and the Gran Sasso experiments, BOREXINO, ICARUS, LVD and OPERA will be making new measurements with pulsed beams from CERN in May to give us the final verdict.”
The article also mentions recent advancements in using neutrinos for communication:
Even if neutrinos are not able to travel faster than the speed of light, the subatomic particles harbor other interesting abilities. A recent experiment by researchers at the University of Rochester and North Carolina State University found that neutrinos can communicate messages through solid materials.

The scientists beamed neutrinos through approximately 780 feet of stone, spelling out the word “neutrinos” on the other side. The research team believes that neutrino communication technology could have numerous uses in the not-so-distant future.

Neutrinos are nearly massless and they have a neutral electric charge. This means that neutrinos are not subject to magnetic attractions and are not significantly impacted by gravity, which allows them to move through solids and liquids without being impeded.

While neutrinos may not be able to move faster than the speed of light, their construction certainly has significant implications for the future of space and underwater communications.
