No, there is an apparent issue. If matter flew at the speed of light away form the center of the universe for 14 billion years, then that would seem to mean that the universe could only be 28 billion light-years wide, The fact that it is wider seems to suggest that matter flew faster than the current speed of light.
Center of the universe? HUGE LOL. Which universe? https://www.youtube.com/watch?v=p4Gotl9vRGs
You were making excellent points.
But then maybe the universe is older than they estimate currently.
Only in the very first minor fraction of a second is it thought (by some, based on Inflation theory) that the universe expanded as fast, actually many many times faster, than light.
