The arguments are given that exotic smooth ℝ 4 's can be considered as the natural counterpart for geometry of quantum gravity in some limits. This follows from the relations of these exotics to ℤ 2 orientifolds of WZW models on SU(2), abelian gerbes on S 3 , generalized Hitchin's–Gualtieri structures as well gerbes on some orbifolds. Non‐standard smoothings of ℝ 4 seem to carry also quantum information about spacetime and gravity.
