Following that line of thought, using the standard cosmological principles and gravitational laws, the Friedmann equations are obtained in terms of energy densities. That is called-for, since the values of energy densities are estimated using the standard cosmological model, where dark matter is included. After a brief discussion of possible candidates for dark matter, the weakly interacting massive particles (WIMPs) are treated in more detail. They are considered as a favourable candidate because the assumption that dark matter has a relic density, after decoupling in the early stages of the Universe, is in harmony with the properties of WIMPs. Finally, a brief summary covers the ongoing experimental search for the direct and indirect detection of dark matterHipotezo o temni snovi podpremo z navedbo nekaterih ustreznih opazovalnih dokazov. Z uporabo standardnih kozmoloških načel in gravitacijskih zakonov dobimo Friedmannove enačbe v obliki gostot energije, katerih vrednosti so trenutno ocenjene z uporabo standardnega kozmološkega modela, v katerega je vključena temna snov. Med možnimi kandidati za temno snov obravnavamo šibko interagujoče masivne delce (WIMP). Ti veljajo za ugodnega kandidata, saj je predpostavka, da ima temna snov po razpadu v zgodnjih fazah vesolja reliktno gostoto, skladna z lastnostmi WIMP-ov. Na koncu podamo kratek povzetek trenutnega eksperimentalnega iskanja za neposredno in posredno odkrivanje temne snoviTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of Slovenia
