I'm very skeptical about this. It seems like every time a "supposed" scientific discovery gets published in the media before a peer-reviewed journal, it's almost always wrong. The same thing happened with cold fusion, Ida (aka. Darwinius) the supposed "missing link" between human and ape, and NASA's "supposed" discovery of bacterium growth through arsenic instead of phosphorus. It's always disheartening when science…

This wasn't characterized as a discovery, either by the reporter or the scientists involved. But it is really interesting. Either you didn't RTFA or I'm not sure what you're complaining about.

If this result is valid then it would mean that neutrinos are capable of traveling .0025% faster than light. There was a supernova that we observed in 1987 (SN 1987) that occurred 168,000 light years away from us. A neutrino burst was observed in 3 different labs about 3 hours before the light was observed. If neutrinos are capable of traveling .0025% faster than the speed of light then why would we observe these neu…

those neutrino's could be from anywhere in the universe. we measured them 3 hours before the light of the supernova because we were looking for them at that time

Right, because those scientists were psychic? Neutrino observatories look for neutrinos continuously. They do not throw away data, if there are neutrinos detected they will be logged. Never in the long history of neutrino observation has there been a spike in detections similar to what was observed with SN 1987a. Moreover, that observation heavily confirms our pre-existing models of neutrino generation and behavior in Type II supernovae.

I desperately want to believe that this will somehow enable us to live in a Star-Trek future, even though I'm sure it won't. Would someone with some knowledge of physics care to break down the ramifications of this (if it's not some sort of measurement error)? Please?

In any case, I'd like to submit my resume to the Time Travel Bureau. I am a computer collector and I am very familiar with many of the technologies time travelers from the future may want to procure. ;-)

Why would they procure them from you rather than go get a fresh new one from the day it was made?

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.

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.

The Star Trek future, ie. travel with speed faster than light, will most likely happen through "warp drive", ie. using the space expansion(contraction) - this is how the natural faster than light movement does happen in the current Universe, and it doesn't violate Special Relativity. Special Relativity holds only for space with static and continuous metric (to preview the complexity of the theory otherwise, try to pl…

Correction, my bad: estimated time dilation variations integral along the neutrinos path is several orders of magnitude smaller than the billionth.

I'm not selling the devices - I'm selling the expertise ;-) How do you know the best time and place to buy, say, a Mattel Aquarius or an A-series Unisys mainframe on an ISA board?

>i think, if they integrate Earth gravity time dilation variations along the neutrinos path.

Isnt that effect in the reference frame of the neutrinos and not the measuring instrument(I'm not too sure about this)?....And also wouldnt it mean that the neutrinos take more time instead of less time?
