I just hope that MINOS, an experiment that will repeat this measurement, doesn't share the same systemic error sources. :/ For example, if they also rely on GPS in the same way as OPERA, it could give a similar false signal. Personally I would be very surprised if the neutrinos actually turn out to travel faster than light, would make so little sense for me from a theory point of view, but we will see. Would be cool if true though!  | ||

The problem is that nothing goes from one point (source of neutrino) to another (detector) without interacting with matter like neutrinos. We can't really repeat the experiment say for electrons or photons. | ||

If we ask nicely, do you think EU will fund a 732km vacuum pumped tunnel so we can shoot electrons alongside the neutrinos? That should help systematics a lot.  | ||

It is being investigated, which is needed to say something conclusively. The update says that there are 2 opposite effecting potential problems they are trying to eliminate in new experiments. | ||

And to add to that; Even if this is true the strange thing is that they measured particles that goes just as fast as speed of light as well, now IF this equipment DID a systematic error it should had been consisted for every attempt and not register different speeds. as above poster pointed out, they don't know yet and need to make adjustments to the equipment before they can say something for certain. | ||

Are you 100% fucking retarded? How is changing everything we know about something we actually don't know much about bad? It's amazing! It will be so awesome to actually be able to figure out physics properly, or to just finally have confirmation that what we know is right! User was warned for this post | ||

"Someone doesn't have the same worldview as me, better call him 100% fucking retarded!" By the way, there is plenty of confirmation that Einstein's relativity is correct, beginning with the solar eclipse back in 1919. | ||

Also, you should do some research about the experiments in 1919 because they did not confirm Einstein's general relativity at all, the data from those experiments was entirely inconclusive. Eddington even threw out 18 of the 28 plates which had a mean closer to what Newtonian theory predicted. Check out The Golem by Collins and Pinch, they go through a series of interesting experiments like this. | ||

I think he meant unfortunately because if matter can travel faster than light its blimp of hope we can someday explore the stars | ||

By the way, there is plenty of confirmation that Einstein's relativity is correct, beginning with the solar eclipse back in 1919. The only thing we can say is that, Einstein's relativity was backed up by all the observations we've made so far. But who knows, we may observe in the future phenomenons that relativity fails to explain. I think it'd be very exciting to observe such thing, and that's why i'd be disappointed if the FTL neutrino thing ends up being a mistake (though it will probably end up like this). Einstein's theory could very well be what Newtonian mechanic is nowadays: a good approximation of a broader theory, under certain constraints. Maybe that's what you meant when saying relativity is correct, sorry if this was the case. | ||

Finding something traveling faster than the speed of light offers a lot of insight on how possibly we too might move faster than the speed of light. Now lets all kiss and make up. | ||
