This is a total pedant thing and nobody will ever be confused about this but topologically a sphere is just the shell and a ball is the whole thing. Just like a circle is defined as the locus of points that are equidistant from a center so is a sphere (a filled circle would be a 2d ball lol).
I wonder how much bigger the sphere would be if we packed it all onto the shell only a 1/16 inch thick (or mm whatever).
