Hey
I was reading about an experiment that slows light down to 1 mile an hour:

What i wanted to ask was, if light slows down, does it gain mass whilst it is moving slower than its maximum speed limit in a vacuum, in effect building "potential energy" for when it exits an object that slows it down, then shoots off to maximum speed in a vacuum again ? ?
If light escapes an object that slowed it down, where is the force that speeds it back up once its left that object, instead of just staying at the speed it was slowed down to.
Shouldn't there be some kind of force that accelerates when it leaves the object, perhaps by expelling mass or something ?
