I chose this particular link because of the headline, specifically the addendum According to One Experiment. If it’s not reproducible, then it will go down in the annals of science as a fluke measurement.
[T]he result would be so revolutionary that it’s sure to be met with skepticism all over the world. “I suspect that the bulk of the scientific community will not take this as a definitive result unless it can be reproduced by at least one and preferably several experiments,” says V. Alan Kostelecky, a theorist at Indiana University, Bloomington. He adds, however, “I’d be delighted if it were true.”
It’s important to note that the experimenters are not claiming to have overturned relativity and are calling for independent confirmation. If you read otherwise, that’s the journalists or editors trying to show some scientific cleavage.
Another reason I chose this article was that they mentioned how the timing was done, because that’s a likely candidate for introducing error.
Jung, who is spokesperson for a similar experiment in Japan called T2K, says the tricky part is accurately measuring the time between when the neutrinos are born by slamming a burst of protons into a solid target and when they actually reach the detector. That timing relies on the global positioning system, and the GPS measurements can have uncertainties of tens of nanoseconds. “I would be very interested in how they got a 10-nanosecond uncertainty, because from the systematics of GPS and the electronics, I think that’s a very hard number to get.”
Some other commentary: This Extraordinary Claim Requires Extraordinary Evidence!
Update: Here is the CERN press release
Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny. The collaboration’s result is available on the preprint server arxiv.org: http://arxiv.org/abs/1109.4897
