Query: Forbidden Landscape from Holography   We present a class of field configurations that are forbidden in the quantum
gravity because of inconsistency in the dual field theory from holography.
Scale invariant but non-conformal field theories are impossible in (1+1)
dimension, and so should be the corresponding gravity dual. In particular, the
"spontaneous Lorentz symmetry breaking" models and the "ghost condensation"
models, which are well-studied in phenomenology literatures, are forbidden in
any consistent quantum theories of gravity in (1+2) dimension since they
predict such inconsistent field configurations.
