Abstract

The modern concentration of relic 't Hooft-Polyakov monopoles is shown to amount to ~ 10-19 cm-3, being determined by the diffusion annihilation rate at t<10-5 s. To eliminate the contradiction with experimental upper limits some mechanism similar to quark confinement should forbid free monopole existence.
