Total agreement with the Andro-man.

There are three dimensions. Only. You can make
anything with the three.

The arena where we have unlimited freedom to make more
realities is in the area of SCOPE. I can declare an
atom to be a galaxy. I can declare that this atom's
electrons are exactly like a galaxy's arms of stars.
I can declare that these arms of stars contain a Sun
just like our sun with an Earth around it.

Voil=E0. Tiny dimensions- not curled up, just small. A whole new
faster Time and a whole new Universe, albeit the Milky Way
may now actually BE part of a chocolate bar. And the suns making
up the electron arms of this Carbon Atom in this chocolate bar are
themselves composed of tiny atoms, whose whirling electrons
are themselves tinier suns, with ever smaller planets and life forms
and
intelligence orbitting them and again a whole new Time defined
by their much faster movement..

Complexity does not diminish with size. It cannot.
Our foundations cannot be amorphous- - -building blocks
need shape just as much as what is built from them.
There can be no smallest just as there can be no biggest- we
live in an infinite Universe. Those who draw lines in the sand
will find it is just that. Sand.
