We can see things moving faster than light

how convenient is it that the age of the universe and the size of the hubble sphere are the same? I wouldn't say its just a matter of luck. I thinks its a sign that our understanding of the expansion of the universe is actually wrong.   if the age of the universe is 13.9 billion years, and the "Hubble sphere" which is the point in space where the cumulative expansion of the universe is at that point faster than light (relative to us) also happens to be exactly the same, then our understanding of how this works is probably wrong.  its simple. you take the speed of light, 299,792km/s divide it by hubbles constant, 70km/s, you get 4,282 megaparsecs.   Want to guess how many megaparsecs they are in a light year?  There is 3261563.8 light years per megaparsec.  so multiply that by 4,282 and you get about 13.9 billion light years.    - Far too convenient.  So, what does this mean?
