dimensions

a tube-within-a-tube presumes 3-D
a gut would cleave a 2-D cell in two
constrained to such dimensionality
for 'in' and 'out' one orifice must do
one 'D' of Time plus three of Space makes four
in which we navigate our conscious lives
but what's a mind to do with seven more
when I can't even visualize five
StringTheory says we're looking at a brane
and hadrons don't deserve so large a role
but SuperSymmetry drives men insane
grad-students swallowed up like by Black Holes
this rabbit-hole could drive one 'round the bend
as guess piles on conjecture without end
