| 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. |
