I do understand - obviously far more than you do. All that you seem to understand is misleading statements from frenzied media. What you are missing is the physics. I have tried to explain it to you but you do not understand. Read:
What you are seing in the cesium experiment is the motion of an effect not a thing. Hopefully the article clears this up for you because you do not understand.
What the article clears up is the fact that the objection to the observation(s) is made on philosophical grounds.
More importantly, the relativistic notion of simultaneity makes it clear that no information can travel faster than light without throwing all our concepts of cause and effect into disarray. Relativity teaches us that if two space-time events are separated so that they cannot be connected by any signal travelling at c or less, then different observers will disagree as to which of the two events came first. Since most physicists still believe that cause needs to precede effect, we conclude that no information can be transmitted faster than the speed of light.
Not very impressive. And I find the premise that one can tinker with definitions in order to give the illusion of explaining away observations rather stinky. Light didn't used to be defined as "information".
