Determining the exact location of the Big Bang is a complex question that requires a deep understanding of the early universe and its expansion. While the galaxy you mentioned formed relatively early in cosmic history, about 250 million years after the Big Bang, it is essential to note that the universe has undergone significant expansion since then. The expansion of space itself means that objects, including galaxies, have been moving away from each other.
The current scientific understanding of the universe's expansion suggests that space itself has been stretching uniformly in all directions since the Big Bang. This means that any particular location in the early universe would have experienced expansion and moved away from its original position.
Additionally, it is important to consider that our observational capabilities are limited when it comes to studying the early universe. The cosmic microwave background radiation (CMB), which is the afterglow of the Big Bang, provides valuable information about the early universe. However, it is not a direct map of the exact location of the Big Bang.
The concept of the Big Bang is a description of the initial rapid expansion of the universe as a whole. It is not like an explosion that occurred at a specific point in space. Instead, it describes the expansion of space itself from an extremely hot and dense state.
To summarize, pinpointing the exact location of the Big Bang is a complex matter due to the expansion of the universe and the limitations of our observational capabilities. While the galaxy formed relatively early in cosmic history, it has likely moved significantly from its original position due to the expansion of space.
