Indeterministic Quantum Gravity IV. The Cosmic-length Universe and the Problem of the Missing Dark Matter

This paper is a sequel of the series of papers [gr-qc/9409010, gr-qc/9505034, gr-qc/9603022], being an immediate continuation and development of the latter of them. In the Friedmann universe, the equation ${\mathrm{\Omega }}_0=2q_0$ holds ($\mathrm{\Omega }$ is density parameter, $q$ is deceleration parameter, and subscript 0 indicates present-day values), which gives rise to the problem of the missing matter as observational data give ${\mathrm{\Omega }}_0<2q_0$. In the cosmic-length universe, ${\mathrm{\Omega }}_0=2q_0-L\mathrm{/}{R}_0^3{H}_0^2$ ($R_0$ is the radius of the universe, $H_0$ is Hubble constant), which lifts the problem. The cosmic length, $L=const \approx 1/H_0$, is the infimum of the set of maximal radii of a closed universe.
