    Okay, i finnaly found it, in a past thread I mentioned it, but that thread is so old now.. I dont think anyone will notice if I post this there. So I'm making a new topic for it. I read this article long time ago, and wasnt sure if it was true or not, can someone please shed some light on it for me.

    Speed of light Exceeded Article

    Okay, i know domain name of this site is a bit corney, but i think I orginally read it at somewhere else.. it says at the top of the article it was originally a New york times news report.
