While it's incredibly impressive that they managed to create a medium through which light travels part way, then stops, it's not contrary to what we already know.

15 Years ago (ok, 20..) my physics prof's were quite SURE you would never be able to stop light. Slow it down in diffrent substances sure but stop? No way not possible. <-- Notes from actual conversation.

Oh and one bit of trivia, Einstein himself NEVER said FTL travel was impossible. That thought was added by others.
