Only if you insist on using a two-dimensional surface; a full globe can
be much more accurate.  That implies that there is a TOE, but it might
remain beyond our ability to formulate or understand from within the
limitations of too few dimensions.

I would hope that at least the mathematics can be worked out, though.
