We consider the gravity field of a Bose-Einstein condensate in a quantum superposition. The gravity field then is also in a quantum superposition which is in principle observable. Hence we have ``quantum gravity'' far away from the so-called Planck scale.

Non-quantized gravity models that preserve Galilean invariance and reproduce Newtonian interaction on average require a minimal noise injection to remain non-entangling.
