Neutrinos Send Message Through 780 Feet of Stone

 Right now, Wi-Fi works by sending messages around the Earth. But what if you could go through the Earth? This would certainly revolutionize technology, as data transfer would be much faster. This idea may seem impossible, because you'd think that a particle can't travel through planets, but in truth, exotic particles named neutrinos can do it. And that was exactly the idea behind a recent experiment at Rochester.

Physicists at Rochester just sent a binary message spelling out "neutrino,z" encoded in neutrinos through 780 feet of pure stone. Yes; the neutrinos traveled through it. Unfortunately, this type of technology won't be available any time soon unless you're willing to buy your own particle accelerator (and they aren't so cheap). However, it is quite a creative idea that could one day revolutionize the world of wireless internet.

Seriously? Speeding Neutrinos Were Caused by a Loose Wire

Now Einstein really has the right to laugh...
 Last September, neutrinos reportedly traveled from Switzerland to Italy faster than light would. This meant that either there was an error in the expirement, or that Einstein's theories were incorrect. Because it seemed so unlikely that Einstein would be wrong, scientists assumed that there was an error in the testing. But when CERN repeated the experiment 20 times and got the same results, that almost crossed off the idea of testing error, so it seemed as if Einstein's theories were false. Yet, scientists all over the world couldn't find any error in the theories. Even CERN's director of research, Sergio Bertolucci, jokingly said, "I have difficulty to believe it, because nothing arrives in Italy ahead of time."

But now, our explanation is finally here; a loose fiber optic cable in the system caused one of the atomic clocks to produce incorrect readings of the neutrino's time. However, we shouldn't jump to conclusions as many people did when the reports first came out; this report hasn't been confirmed, only one source, ScienceInsider, has mentioned it. Apparently, CERN's researchers will retest with properly hooked clocks, and this should tell for sure whether the results were in fact due to a loose wire. Talk about overthinking it...
