The IIB matrix model has been suggested as a particular formulation of nonperturbative superstring theory (M-theory).
It has now been realized that the emerging classical spacetime may reside in its large-N master field.
This bosonic master field can, in principle, give rise to Minkowski and Roberson-Walker spacetimes.
The outstanding task is to solve the bosonic master-field equation, which is essentially an algebraic equation.
First results have been obtained for small values of the matrix size N.
This talk focuses on the basic ideas and open questions, while skipping most of the technical details.
