We live in the center of a sphere of radius 13.7 light years constituting our Universe. The big bang theory considers the state of our universe before the expansion starts from an original point located somewhere around us.
Suppose there is a conscious life form somewhere in our universe. Their universe does not overlap with ours and their big bang takes place at the center of their sphere.
Is there a reason for their expansion to coincide with ours?
And there should be as many big bangs as there are consciousnesses.
The easiest way to solve this paradox is to assume that we are the only consciousness in the universe, right?
And, there we are brought back to middle-aged thought where man is at the center of the world, which raises the question of the origin of life.
In short, I am very uncomfortable with this aspect of the big bang.
