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! :confused:

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.

Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
