VANCOUVER , British Columbia — Physicists stun the human race last yr by announcing they ’d seen signs that atom call neutrinos were journey quicker than light — a feat thought to be proven impossible by Einstein . Ever since , other researchers have been racing to try the experimentation on their own to see if the determination hold up up .
Some results of these tests should be foretell this spring , scientist said Friday ( Feb. 17 ) here at the annual group meeting of the American Association for the Advancement of Science .
Einstein’s theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second), as a cosmic speed limit. Some researchers think they may have broken this limit, and the implications are mind bending.
" It ’s very voiceless to find an misplay by reading a paper , " said particle physicist Rob Roser of the Fermi National Accelerator Laboratory ( Fermilab ) in Batavia , Ill. , who was not involved inthe original experimentation . " What you need is for someone else to make the measurement . We ’ll see what happens . "
scandalous finding
The freakish finding was first reported in September 2011 , when physicists at the CERN research lab in Geneva , Switzerland , announce that an experiment called OPERA had measure the bantam subatomic molecule plainly dampen what was thought to bethe ultimate cosmic upper limit point .
OPERA sends neutrino 454 miles ( 730 kilometre ) underground to the INFN Gran Sasso Laboratory in Italy , and measures how fast they take to make the trip . While researchers expected the almost - massless mote to travel at near light upper , they really appeared to arrive at their finish about 60 billionth of a second preferably than light would have .
If this really occurred , it would contradict Albert Einstein ’s special theory of relativity , and throw much of physics into upheaval . [ 10 Implications of Faster - Than - Light Neutrinos ]
twofold check
The uncovering was met withshock and incredulity by most physicists , include the penis of the OPERA team themselves .
Joked Sergio Bertolucci , inquiry director at CERN , the finding is hard to believe because " nothing in Italy come ahead of meter . "
The researchers directly invite other experts to count in and essay to procreate their event to either corroborate or disprove the determination . And that ’s just what they ’ve been doing .
Several attempt to vivify the OPERA experiment have been undertake around the world , include one in Japan called T2 K ( Tokai to Kamioka ) , and another , calledMINOS , at Fermilab .
MINOS sends neutrino from its positioning near Chicago to a mine in northerly Minnesota . Last twilight , MINOS did n’t have the ripe equipment to make a mensuration tender enough to evidence or disprove the OPERA results . Since then , the research laboratory has install new ironware and started up the experiment .
" They started two weeks ago take in data point , " Roser said . " I would expect you would hear in May or June what Fermilab ’s answer is . "
Other sources of erroneousness
In accession to looking to out-of-door measure , the OPERA researchers have tweaked their experimental frame-up to addressconcerns raised by other scientistsabout likely sources of error .
For example , some vex that theuse of GPS satellitesto metre the going of the neutrinos from CERN in the original experimentation was introducing flaws . In response , the OPERA physicists conduct the experiment again , using only nuclear clocks to measure timing , and still come up with the same result .
" They ’ve changed a routine of things , which might have land them into some doubt , " Bertolucci said . " It is very hard and the fact that nobody was able to obtain an light solution immediately means essentially they ’ve done their Book of Job . "
If other experiments like MINOS and T2 K also measureneutrinos traveling quicker than scant , it does n’t find out that an error no one cerebration of is plague all the experiment . However , it makes the likeliness of an error much more remote , Roser said .
" I do n’t bang which I ’m root for , " Roser told LiveScence . " If three or four different experiments around the world see the same thing it ’s hard not to be convince . "
For evidence that sometimes lurid results are true , Bertolucci pointed to the celebrated 1887 experiment by Albert Michelson and Edward Morley that disproved the notion , popular at the time , that the universe was filled with a metier that carry light called an ethyl ether .
" They found a result all out or keeping with the present hypothesis of the time , but they were right , " Bertolucci said . " We have to just keep an candid mind . "
