It is akin to the 'membrane interaction' posited by some string theorists, I think.
Concerning the sidebar on subscript/superscript designations - I'd add that Wesson shorthands his theory like this: "5D2T" meaning five dimensions, two of which are time dimensions - spatial being the default D.
In that shorthand 0D would be the only point (the Big Bang singularity), 1D a line, 2D a plane, 3D a cube, 4D a tesseract, etc. However, when we shorthand 4D concerning space/time, the 1T is assumed (4D1T). LOLOL!
So I guess the bottom line is whether the shorthand is communicative.
In Hebrew, the command is simply, “Light be.”
