Cosmic voids and filaments from quantum gravity
  Using computer simulations we study the geometry of a typical quantum
universe, i.e. the geometry one might expect before a possible period of
inflation. We display it using coordinates defined by means of four classical
scalar fields satisfying the Laplace equation with non-trivial boundary
conditions. The field configurations reveal cosmic web structures surprisingly
similar to the ones observed in the present-day Universe. Inflation might make
these structures relevant for our Universe.
