You remember the surprising news we reported back in September: Neutrinos Move Faster Than Light? We’ve also posted a few updates: on 15 Oct ’11 and then 28 Oct ’11, when it was reported that CERN was going to run the test again.
Well, they’ve done it, and the BBC reports Neutrino experiment repeat at Cern finds same result. If you care about this you’re going to click over there to read it all, so we’ll just provide a few excerpts, with a bit of bold font added for emphasis:
The team which found that neutrinos may travel faster than light has carried out an improved version of their experiment – and confirmed the result. If confirmed by other experiments, the find could undermine one of the basic principles of modern physics.
No big deal, right? Here’s more:
Critics of the first report in September had said that the long bunches of neutrinos (tiny particles) used could introduce an error into the test. The new work used much shorter bunches.
Okay, it wasn’t that. Let’s read on:
The error in the length of the bunches, however, is just the largest among several potential sources of uncertainty in the measurement, which must all now be addressed in turn; these mostly centre on the precise departure and arrival times of the bunches.
This is like the biggest suspense thriller in the universe. We continue:
Next year, teams working on two other experiments at Gran Sasso experiments – Borexino and Icarus – will begin independent cross-checks of Opera’s results.
The US Minos experiment and Japan’s T2K experiment will also test the observations. It is likely to be several months before they report back.
That’s it. You’ll have to hang on a few more months, dear reader. But don’t worry — the only thing we’re waiting for is to learn the nature of the universe.
