If it is faster than light, how can they keep up with it to build it....
It's so fast that you can't see it.
So, as in other things we can't see or understand, we will have to take the experts word that it actually exists.
Sort of like Obama's economic recovery, shovel-ready jobs, The Emperor's New Clothes, Global Warming & Climate Change.

“If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?” - Stephen Wright
Good question but for what it's worth, they won't need headlights.......That'll save some bucks.
