Science: Don't Worry, Physics Is Safe

Remember those faster-than-light particles discovered last month? The ones that threatened our notions of how realism functions? Science now has an explanation for that.

Those of you World Health Organization religiously follow our coverage of science volition recall an clause from the end of final stage month in which we relayed the news that scientists had discovered minute particles that were apparently traveling faster than the c. As I wrote at the time, this is just not supposed to take place and the worldwide knowledge domain residential area was overcome by a refrain of "harumphs" and monocles soft out of place.

Now it seems the sciencefolk have an explanation for the phenomenon.

Long story, pint-sized, relativity is a harsh, confusing mistress that screwed skyward the scientists' ability to accurately measure the distance between where the particles originated, where they ended up and the amount of time that their trip took.

Overnight level, long, Dvice reports:

To understand how Einstein's theory of relativity altered the neutrino try out, it helps to pretend that we'ray hanging out on 1 of those GPS satellites, watching the Earth live by underneath you. Think of, from the reference frame of someone connected the satellite, we'Ra not aflare, but the Dry land is. As the neutrino experiment goes by, we set out timing one of the neutrinos A it exits the source in Switzerland. Meanwhile, the detector in Italy is moving just as meteoric American Samoa the rest of the Earthly concern, and from our position information technology's moving towards the source. This means that the neutrino leave have a slightly shorter distance to go by than it would if the experiment were stationary. We stop timing the neutrino when it arrives in Italia, and calculate that it moves at a hasten that's well below the amphetamine of light.

"That makes sense," we enounce, and send the start sentence and the stop clip down to our colleagues on Earth, who take one look at our numbers and freak. "That doesn't nominate sense," they pronounce. "On that point's no way that a neutrino could have covered the distance we're measuring down here in the time you measured upward at that place without going faster than light!"

And they're totally, 100% correct, because the distance that the neutrinos had to travel in their frame of reference is longer than the distance that the neutrinos had to go by in our reference frame, because in our mention frame, the detector was moving towards the root. In separate language, the GPS time is bang connected the nose, but since the clock is in a different reference frame, you have to compensate for relativity if you're leaving to use information technology to make extremely surgical measurements.

Scientists at the University of Groningen in Kingdom of The Netherlands did the math, and supported this hypothesis, the neutrinos should have picked up an extra 32 nanoseconds of relativity from each of the cardinal "observers." Given that the average amount of unaccounted for time in the 15,000 experiments originally performed at CERN was 64 nanoseconds, that lines up nicely.

And, A a depressing final result, ruins any chance we might've had at harnessing the power of superluminal particles. Sorry Billy, looks like you won't be acquiring that dinosaur for Christmastide. Those science jerks had to go and ruin it for you.
