:::Wouldn't that depend upon how fast the light traveled at the time of origin (creation or big bang or whatever)? Perhaps light traveled at a fast rate initially, and slowed over time? 39 billion or 13 billion would not be a constant, only best guess estimate based on observation at this moment in time, and is slowing down. It's like throwing a rock in a pond -- the initial ripples occur very fast, but over time as it spreads further out it slows down. Nothing is constant; everything is constantly changing. So whatever the distance observed today, it's only an approximation based upon limited data from the initial moment of origin.  [[User:RobSmith|Rob Smith]] 19:29, 30 January 2012 (EST)
