    $\begingroup$ This seems to be based on the "expansion of matter from a point in space" misconception. The language of "ejected in a spherical pattern" seems to indicate that you think it was ejected from somewhere (a "centre" to the universe) No such centre exists. $\endgroup$

    $\begingroup$ I've voted to close, as I don't think this is directly answerable. It isn't a direct duplicate of the linked question, but it assumes something that isn't true: that "radial", "perpendicular" "origin" "spherical pattern" and "other side" have any kind of meaning when applied to the expansion of the universe and the big bang. They don't, which makes the question un-answerable. $\endgroup$

    $\begingroup$ I'm using simple terms for visualization. The "origin" is the point of emanation, the singularity. "Sphere" is not intended to mean an actual shape, but whatever odd shape the universe had as it began to expand and continued. The universe didn't expand in one direction. Like a balloon, it expanded in all directions - we have no idea how uniform that shape might have been, but for this discussion, we can visualize it as "spherical". "Perpendicular" was simply an example of an angle relative to our point of reference. Any angle is valid. "Radial" just means the direction we're looking. $\endgroup$

    $\begingroup$ @Tony. exactly! There is no point of emanation. The singularity is not a point in space. And so the entire framing of the question points to a fundamental misconception. The links that PM2ring posted may address this. $\endgroup$
