  The comparison of the Standard Cosmological Model (SCM) with astronomical
observations, i.e. theory versus experiment, and with the Minimal Standard
Model (MSM) in particle physics, i.e. theory versus theory, is discussed. The
main issue of this talk is whether cosmology indicates new physics beyond the
standard $SU(3)\times SU(2)\times U(1)$ model with minimal particle content.
The answer to this question is strongly and definitely "YES". New, yet unknown,
physics exists and cosmology presents very weighty arguments in its favor.
