Mathematically that poses a serious problem. The universe expanding from the big bang would have to be at least older than the time it would take to disperse the matter of the universe to all of its furthest points. I calculate 12 billion light years as 12 billion x the length of a light year. Is that not accurate? though my calculator and math skills are somewhat limited, how is this possible?

Could enough ice slow down light? Love the video. Could enough ice slow down light?
