The old tricks are still the best tricks I see. A little scientific heresy goes a long way. I am of coarse happy that most of you didn't buy into the absurd, but I am a little disappointed that none of you could point out the real flaw in the argument. Falling back on definitions is a poor substitute for a genuine explanation of what exactly is going on, and why the result is counter intuitive.
The light isn't actually slowing down, and no the medium doesn't alter the properties of light. The light is moving at the same speed regardless of where it is be it a vacuum or a pool of water. The only thing that a medium does change in respect to the light is the distance that must be traveled. The light is being forced to bounce around a great many times before it comes out the other side. So it shouldn't be treated as if it is moving in a straight line between two points. It is all a trick of measurement from the perspective of an outside observer.
A more mundane explanation would be someone trying to calculate the speed of a race car by measuring the circular track, and the time it took for the car to complete the race. That is well and fine if the car only has to race one lap, but in real life we know that such races take hours to complete, because the car has to go around that small track hundreds of times. The reality isn't that the car is moving slower, but that the distance it needs to drive has become greater.
Kudos to those who saw that Quantum Tunneling had jack shit to do with faster then light. It in no way allows for a particle to move faster then the speed of light, or to disappear and reappear at a distance greater then could be traveled in General Relativity.
