In agreement with the relationships that I have been discussing here
between the 4 fundamental interactions (although they are undoubtedly
unaware of this thread), South Korea has just related QCD to a
possible theory of Quantum Gravity.

D. G. Pak of the Center for Theoretical Physics, Seoul National
University South Korea, in "Confinement, vacuum structure: from QCD To
Quantum Gravity," arXiv: 1005.0110 v1 [gr-qc] 2010, 7 pages, finds
that the structure of QCD is analogous to that of a possible theory of
Quantum Gravity.

They use a minimal Lorentz gauge gravitation model with R^2 type
Lagrangian.

I will try to discuss this more later.
