Another study proves Einstein right through examination of high-energy neutrinos

Another study supports Einstein's theory of special relativity by examining neutrinos.

Yet another study has proved Einstein's theory of special relativity by supporting Lorentz symmetry, which states that any scientist should see identical laws of physics in any direction if the object is traveling at a constant speed.

The team of MIT researchers examined two years of data from theIceCube Neutrino Observatory, which is a massive neutrino detector located underneath Antarctice ice. Their analysis revealed no abnormalities in normal neutrino oscillation that would indicate a Lorentz-violating field.

"People love tests of Einstein's theory," said Janet Conrad, a professor of physics at MIT and a lead author on the paper. "I can't tell if people are cheering for him to be right or wrong, but he wins in this one, and that's kind of great. To be able to come up with as versatile a theory as he has done is an incredible thing."

"We were able to set limits on this hypothetical field that are much, much better than any that have been produced before," Conrad added. "This was an attempt to go out and look at new territory we hadn't looked at before and see if there are any problems in that space, and there aren't. But that doesn't stop us from looking further."

The results effectively rule out the possibility that neutrinos within the high energy range examined in the study violate Lorentz symmetry and support the possibility that neutrinos behave just as Einstein's theory predicts.

"Every paper that comes out of particle physics assumes that Einstein is right, and all the rest of our work builds on that," Conrad said. "And to a very good approximation, he's correct. It is a fundamental fabric of our theory. So trying to understand whether there are any deviations to it is a really important thing to do."

The findings were published in Nature Physics.
