Does anyone know if the fastest velocity of light is not fastest anymore?

    Does anyone know if the fastest velocity of light is not fastest anymore? I think I heard a few days ago, that the light's velocity record has broken. Is it true? Will any of the teachers explain how did that happen, if it really did?

    Re: hello everyone,

    This was not proven out. c is still the limit for signalling.

    Re: hello everyone,

    DrChinese is correct.

    There was some error in the experiment. Neutrinos travel slower than the speed of light

    ok ...DrChinese thank you so much :)

    After checking the equipment another test was made and the results were still that the nutrinos were being detected before expected. (they did travel faster than light) it was also confirmed by an independent group.

    Eh, no. The original group did find a systematic error that most likely cased the earlier false results. When corrected for, the neutrinos turn out NOT to move faster than light. The other independent group also found normal not-faster-than-light speeds.
