 note = {application/pdf, A numerical formulation of d-dimensional quantum gravity on R × Sd−1 is developed based on the d-dimensional dynamical triangulation method. It provides tools to analyze space-time properties of the (d − 1)-dimensional space with sphere topology along the direction R, in which time coordinate can be defined naturally. As examples, we show numerical results of the 2-dimensional (R × S) model, and compare with the matrix model. Furthermore, we measure the 2-space point correlation function on the last scattering surface of 3-dimensional space S3, and compare it to the CMB anisotropy observation results of COBE and WMAP. The numerical simulation exhibits the inflation without any additional fields, and the quantized space-time possesses properties required from observations.},
