  This paper is a continuation of the papers [gr-qc/9409010, gr-qc/9505034]. A
revision of the Einstein equation shows that its dynamic incompleteness,
contrary to a popular opinion, cannot be circumvented by so-called coordinate
conditions. Gravidynamics, i.e., dynamics for gravitational potentials
$g_{\mu\nu}$ is advanced, which differs from geometrodynamics of general
relativity in that the former is based on a projected Einstein equation. Cosmic
gravidynamics, due to a global structure of spacetime, is complete. The most
important result is a possibility of the closed universe with a density below
the critical one.
  Keywords: general relativity, cosmic time, cosmic space, Einstein equation,
