No, no, no,

I have length, never enough...
I have depth, But often to shalow...
and width. Far to much of this... And It would seem that I am existing in this time frame right now.

So maybe I am not so spherical as rhomboid in shape.... Imagine a egg with short legs.

I have at present no understanding of this four dimensional space... You have not helped yet.

There is no problem with the shape of this Galaxy. Spiral structures I understand.
Groups of galaxies and clusters. super clusters and in general the shape of the whole universe I can imagine.
I do not have a understanding of a folding back on itself. String theories., or multi dimensional concepts. If you do? pass it on please.
