I apologize for any confusion caused by my previous response. There seems to be a misunderstanding in your question. The Big Bang did not occur at a specific point in space that objects have traveled from to reach their current locations. Instead, the Big Bang represents the expansion of space itself, where all matter and energy were densely packed into an incredibly hot and dense state.
When we talk about the age of the universe, such as 13.7 billion years, it refers to the time since the Big Bang. It does not imply that objects we observe today have physically traveled a distance of 13.7 billion light-years from a central point.
The expansion of the universe is key to understanding this. In the early stages of the universe, space itself rapidly expanded, causing the distances between objects to increase. It is this expansion that allows light from distant objects to reach us.
When we observe objects that are, for example, 10 billion light-years away, it means that the light we are detecting from those objects has traveled for 10 billion years to reach us. However, due to the expansion of space over that time, the objects are now much farther away than they were when the light was emitted. In other words, the light has taken a long time to reach us, but the objects themselves have actually moved away from us at a rate determined by the expansion of the universe.
So, it is not a case of objects reaching their current locations instantaneously from the initial point of the Big Bang. Rather, the expansion of the universe has caused the objects and the space between them to stretch over time, affecting the distances we observe today.
