Forget about Isotropy (for a moment); The Primeval-Atom is Self.

On the matter of the big bang; it almost seems certain to me that its origin is where the heart is, right here, self, love. The origin of the expansion lies at the center of the earth. Furthermore, the expansion happened gradually and uniformly and it will continue to do so. The answer to the question as to what the primeval-atom is is self. The answer to the question as to what is self is love. The answer to the question as to what is love is the need for warmth and togetherness that results in it itself existing as existence. Existence itself is Love, Love (it)Self exists, Self is Love. In other words; 'Love binds itself together'.
