my TOE is to quantize the Einstein's metric expressed as
. In matrix notation, its elements are given by the following
g11=-1, g12=0, g13=0, g14=0
g21=0, g22=-1, g23=0, g24=0
g31=0, g32=0, g33=-1, g34=0
g41=0, g42=0, g43=0, g44=1
in the quantized form, none of the elements has value of zero. But in the homogeneous and isotropic form of at dimension six, it cannot be transformed into the Einstein's metric again.
