I don't want to sound crass, but I would be very interested in seeing some evidence to support this postulation. I consider myself well-read and have never encountered any reading to support your position.

EDIT: Yeah, that 'changing medium' thing - its called the 'refractive index'....

It was in my physics book Last year, which is generally accepted as the best physics text book out there. Unfortunately, I only have volume one of that book now, so I can't look it up to relate it to you.

It is all about reference frames. From our reference frame, the light appears to slow down when going into a thicker medium. But from the reference frame of the light, it has not decreased in speed at all. That is what matters more. Our perception is inherently flawed anyways.
