So I was reading about GN-108036 this morning and for some reason I thought of something which I can't quite wrap my head around and make sense of. It's early morning so maybe coffee hasn't kicked in yet.
If it starts with a central big bang and we now look at something that is 12.9 billion light years away, how can we be here already to "observe" the light if the universe is approx. 13 billion years old?
In other words:
Big Bang, stuff starts expanding.
What will form GN-108036 is part of it
What will eventually form earth is part of it.
Nothing can travel faster than light yet;
12.9 million years after we are at this point "ahead" of the light from GN-108036 to see the light reaching us?
