That just means it can&#x27;t be quantized in a lattice-like structure, it can still be &#x27;foam&#x27;-like with some characteristic length.<p>Also I&#x27;m not entirely convinced that space-time and quantum field theory are completely incompatible. General relativity and Yang-Mills (in the classical limit) fit beautifully together, it would be extremely odd if this becomes impossible when you add quantum physics.
