Query: Spacetime-noncommutativity regime of Loop Quantum Gravity   A recent study by Bojowald and Paily provided a path toward the
identification of an effective quantum-spacetime picture of Loop Quantum
Gravity, applicable in the "Minkowski regime", the regime where the large-scale
(coarse-grained) spacetime metric is flat. A pivotal role in the analysis is
played by Loop-Quantum-Gravity-based modifications to the hypersurface
deformation algebra, which leave a trace in the Minkowski regime. We here show
that the symmetry-algebra results reported by Bojowald and Paily are consistent
with a description of spacetime in the Minkowski regime given in terms of the
$\kappa$-Minkowski noncommutative spacetime, whose relevance for the study of
the quantum-gravity problem had already been proposed for independent reasons.
