We can see things moving faster than light

Not to be nitpicking too much, but you don't actually know the distance to GN-z11. You hypothesize that it's some 39B miles away. I really dislike when people state things as factual, when they aren't factual at all. I find it to be egotistical at the least, to speak in absolutes about subject matter that is wholly hypothesis, without even a thought of mentioning that it IS a hypothesis. That the universe is expanding, is a certainty. By how much and how fast, is speculative at best.
