Created matter filling the void of SpaceTime condition: iLIVE
The consideration of the Big Bang occurring at a single point is that of its one-dimensional condition in SpaceTime; i.e. existence had yet to unfold upon the notion of its traditional fourth-dimensional condition.
In other words, the traditional fourth-dimensional SpaceTime condition always existed and our created matter is just filling the void.
Per the hypothesis, "The galaxy — or mini-galaxy, as NASA is calling it — is thought to have been just 100 million to 200 million years old when its light began the 13.2 billion light-year journey to Hubble's lens."
As I see it, the current SpaceTime distance and its relevance to a creation time per the Big Bang do not necessarily map along this logic.
After existence unfolded into its traditional fourth-dimensional condition (everywhere at the same time), matter began to evolve/ form into larger conglomerations based on the uneven distribution of matter.
Whenever and wherever this farthest galaxy formed, relevant to our SpaceTime position, it has been traveling away from us consistently with the accelerating environment of our universal inflation/ expansion.
The fact that it can be detected at a distance of 13.2 billion light-years from us is a reference that the light-emitting objects within the galaxy were shining at this time of its distance from us.
In other words – as a purely hypothetical example – it may have been formed some six billion years ago (at a considered time of seven billion to eight billion years after the Big Bang) at a distance of 10 billion light years from us and continued to emit light while it was accelerating away from us.
So from our perspective, two billion years ago we might have detected its light at a distance of 10 billion light years from us.
Now we are detecting this light at a distance of 13.2 light-years because we have been moving apart from each other.
So the distance to this farthest galaxy does not tell us when the galaxy was formed relative to the event of the Big Bang; for it this were the case, we would have to come up with a theory in which fourth-dimensional SpaceTime was expanding relative to its unfolding from a single dimensional condition.
