Answer 1

How about explaining how laser light transmitted in fiber optics can pass along information faster than the speed of light?

It is because the light coming out of the fiber optic cable is not the same light going into the cable. When you push light into the cable the pulse coming out is already at the other end of the cable. Think of the transmission of data as being like a stick. You push one end of the stick and the other end pokes your friend in the back. You have transferred energy faster than the speed of light.
