:How is it 'nonsense'? Does light not radiate out in every direction from a source? Infact, it does. So since this is the maximum speed, we can assume that any one portion of the universe is expanding at the speed of light. So things are moving at the speed of light away from each other in opposite directions, resulting in a total speed faster than light, without ever actually going over the speed. 
 :Imagine standing back to back with another person, and walking 10 feet away from each other. When you reach your destination, there will be 20 feet between you, but you never moved more than 10 feet and neither did they. you moved the same distance, and created double that distance as you moved relative to the other person. Bear in mind this is an extreme oversimplification of the idea, and does not take into account the curvature of space. I merely wish to supply a more understandable mental image of the effect, except that the universe would be doing it in every direction simultaneously (which we have observed, yes) where you would only do it across a single small fragment that does not also get larger and only moves in two dimensions. The idea however remains the same.
