Universal Measurements
How big is everything? Well, scientists have measured the entire universe, and it turns out the universe is at least 156 billion light-years wide. Which means that in some 13.7 billion years the universe has been around, the stuff at the edge has become some 78 billion light years from where it started. Meaning that it's an average of well over 5 light years per year from where it started. So if light travels, by definition, one light year per year, and the stuff of the universe travels five, then... it's... moving... faster than light? But... But, you see, silly, it's not, 'cause the universe is expanding. I'd explain better, but at this point it starts involving science. Or at least so they pretend.
