On the time delay of the ultrahigh-energy radiation signal from the source Cygnus X-3

The time delay of the signal from the source Gygnus X-3 detected by EAS observation with E ≥ 3x1014 eV and counted off the maximum of radioburst in October, 1985 is considered. The effect is shown to get the explanation in the framework of the earlier proposed interpretation of the ulrahigh-energy radiation as free gluons. The agreement of this interpretation with the totality of experimental data is emphasized. A possibility of relict gluons to give a significant contribution to the density of a hidden mass in the Universe is discussed
