I'm not sure, but I think it represents uncertainty over the last digits. So 1.000051(29) would be equivalent to 1.000051 +- 0.000029.

Yes, that is what it means. :)

That can't be it because the error wouldn't straddle the speed of light. It would put the range at 1.000022c to 1.000080c, both of which exceed c, so they wouldn't have written it off as error.

A news article where both the scientists and the reporter understate the claims, publish the data, and ask other teams to please prove them wrong. I like this. Most of the time the reporters overstate the research, the scientists keep the data secret, and the general public is left scratching their heads.

It's called impartial news, possible only as a public service

> impartial news

Inherently impossible, a troubling myth that is made all the more troubling by the fact people believe it.

Impartiality is gone the moment the camera is aimed over here as opposed to over there.

Scientists generally do not keep data secret. They try to publish as much as they can actually! This is how you get nice things like funding and tenure! Most of the time reporters misunderstand the research and then oversell it in order to get their story read. The general public is usually left scratching their heads because of this bizarre layer of clueless journalists between them and the scientists. Yes, some sci…

Yes,the mankind would literally need to rewrite physics! It will be so exciting to be a part of it!

About the 70's group, can you share the link to the article?

But for now, he explained, "we are not claiming things, we want just to be helped by the community in understanding our crazy result - because it is crazy".

is it really crazier than nothing being able to travel faster than light? it sure as hell isn't crazier than particles flitting into and out of existence at the subatomic level all the time. the fact is, that most things science has uncovered, particularly in the last 100 years, have been nothing short of hysterical. and for this, dear researchers, i thank you.

Indeed. Compare that with the other article about this currently on the first page of HN: http://hosted.ap.org/dynamic/stories/E/EU_BREAKING_LIGHT_SPE... Which is less cautious and more of the standard fare of not-very-well-reported science. sigh

That's the article that's at the top of reddit right now. I came to Hacker News to see if there was a better article here since the reddit one didn't seem particularly well written.

I forget the source, but they later tested their setup with random input and found it predicted tachyons from that as well.

am i the only one that has come to love the scientific method simply because it creates more questions than it answers. there is just so much that we do not and cannot understand. the more we learn, the less we know. fantastic.

on the flipside, i would be certain that certainty is a particular kind of hell, if having such knowledge didn't condemn me to it. excuse me while i proceed to consume my tail http://en.wikipedia.org/wiki/Ouroboros

This seems to be solid work. First, the group proved that the neutrino speed can be accurately measured in OPERA: http://arxiv.org/abs/1106.2822 http://iopscience.iop.org/1367-2630/13/5/053051 Second, they compared the neutrino results with light results. Third, they ask to replicate the results in some other environment. This is a normal scientific procedure. Please also note the number and variety of authors on thi…

Phil Plait the Bad Astronomer goes into some of the technical challenges the scientists have to overcome in this experiment in laymen's terms. http://blogs.discovermagazine.com/badastronomy/2011/09/22/fa...

Wow, and he's extremely reserved about the whole thing - usually he's like a cold shower, raining on the press's parade. I like the SN1987A counter-example, though - it does raise a few questions. Not even remotely conclusive, but it makes it more puzzling.

Maybe not secret then, but to be released at a later date. Or released in one of those journals that most of cannot access.

No one releases data in journals, at least not in astronomy. There are dedicated sites for this, e.g. http://archive.stsci.edu/ About the later date: I think it's reasonable that those that put together the proposal and thought up the project have a chance at getting their results out first. Otherwise, why would you go through the effort of planning and executing observations if you could just poach someone else's da…

The data cite people http://datacite.org/ are trying to figure out how to create "data papers" and "data journals" that would let publishing data get a "peer-review" status that would help people advance towards tenure.

The Scientific Method could be boiled down to:

10: Question Reality

20: Verify Results

30: GOTO 10
