You know... there was one test they did, that was up for review and research because of the interesting results and I never heard what happened, it just kind of disappeared. Anyhow, the light beam was shot into a tank of special treated noble gases and the amazing thing is the beam appeared on the other side of the room before it even entered the tank, suggesting that the limit HAD been POSSIBLY breached, but it had to be looked into to find out what really happened because to be honest, the scientist were not sure. Anyone know the outcome of this?
