    Tighten a connexion and all the results appear 60 nanoseconds faster.
    Phee-eew!

      Weren't there plans to try & reproduce the 'faster than light' neutrinos in the USA? Does anyone know of it was attempted, & what the results were?

        I don't know Flosshilde but I listened to a few programmes about an author last autumn. He was saying that a CERN type project of this kind had been abandoned in America because of funding problems. He then argued that many of the brilliant scientists there were set to work on new computers to help with financial trading.

        The ones they designed are so fantastic they are largely able to trade on their own but it is also beyond the wit of ordinary financiers to manage them in the human interest. Everything they do is logic and nothing else. Hence, he says, we have the current financial crisis. It was caused by computers that are out of control.

        He was of course promoting his novel which followed these lines but he claimed it was all based on fact.

          Hey, maybe that wiring check I did last week explains how the sounds now come faster out of my speakers!

              There is a cartoon in The Telegraph today of Neutrons whizzing around at Cern and one Neutron is saying to another: It wasn't me travelling faster than the speed of light - it was my wife
              Well, it made me laugh!

                  That's the one I was thinking of - but if my memory is right they were keeping it open just to try & replicate CERN's results. I did put a link to the story back in the trhread, but I'm too lazy to look for it

                    well if this proves to be the final resolution of this story it enhances rather than detracts from the integrity of the science processes involved .... not jumping to conclusions, scepticism, replication peer review and the truth as we know it jim ..... not to forget a simple humility .....

                    coincidentally bbc4 reran Prof B Cox's excellent paen to fusion last night ..... er funding innit .... and very big numbers not adding up to our convenience ...
                    According to the best estimates of astronomers there are at least one hundred billion galaxies in the observable universe.

                        At least, I thought I'd put a link to to the story in this thread, but I've just checked & I hadn't - there must have been an earlier thread on the same topic (& Lateral's first post does suggest that).

                          A repeat of the measurement of the speed of neutrinos finds they do not exceed light speed, in contrast to controversial results reported last year.


                          This looks like confirmation that the previous results were incorrect.

                            Ah ... I also thought there was a previous thread on this, because I think I posted the following thoughts before. However, at the risk of being boringly repetitive, here goes again.

                            I should say that I step forward rather nervously, because although I am a scientist and happy to admit it, my speciality is plant protection and particle physics is as obscure to me as it is to the next man. But what occurs to me, as one who has done a lot of experimenting in my time, is that this anomaly is very small and most likely within the limits of experimental error. These machines, and the machines that record the results from these machines, are made by man (and woman) and are subject to variability. Remember too that the traces on the screen have to be interpreted. It is true that the result has been repeated, but of course, if it is a variability introduced by the machine, or the interpretion, it will be repeatable, because we only have one machine (well, it did cost rather a lot).

                            There would be two ways to strenghten the observation. One would be to improve the accuracy of the machine, or build a more accurate one, though the latter would be prohibitively expensive. The other would be to devise a different way of observing the same effect: clever physicists are probably pondering this, and if they find a way, and the effect is still there, we have something to worry about. Personally, I am happy to believe it is experimental error, and Einstein's theory is still intact.

                              It seems that the observation of neutrinos travelling faster than light was probably due to a faulty connection. This has been previously mentioned in the press but this is a report from today's Independent:

                              The experiment that was supposed to have proved Albert Einstein wrong by showing that sub-atomic particles can travel faster than the speed of light is more than likely to have been an error, scientists said yesterday.
