[azneternity]

Okay, i finnaly found it, in a past thread I mentioned it, but that thread is so old now.. I don't 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.

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.

God I hate posting this, but I must know!

This is a instance of the the group velocity of the frequencies that make up an optical pulse exceeding c. It is a well-studied phenomenon and does not lead to a problem with relativity. The following link contains a discussion of the experiments described in your article.
