Ale v skuto\u010dnosti je to len \u0161pi\u010dka \u013eadovca. V\u00e4\u010d\u0161inu hmoty vo vesm\u00edre tvor\u00ed nie\u010do, \u010do nevid\u00edme – tmav\u00e1 hmota. To je ten nevidite\u013en\u00fd hrdina n\u00e1\u0161ho kozmick\u00e9ho pr\u00edbehu, ktor\u00fd m\u00e1 na svedom\u00ed ove\u013ea viac, ne\u017e by sme si mohli myslie\u0165. Predstavte si, \u017ee vesm\u00edr je ako obrovsk\u00fd koktail. Vidite\u013en\u00e9 hviezdy, plan\u00e9ty a plyn s\u00fa ako \u013eadov\u00e9 kocky a ovocie pl\u00e1vaj\u00face na povrchu. Tmav\u00e1 hmota je tekutina, ktor\u00e1 dr\u017e\u00ed v\u0161etko pokope. Je to t\u00e1 tajn\u00e1 pr\u00edsada, bez ktorej by koktail nefungoval. Je to zauj\u00edmav\u00e9 a tajomn\u00e9.V 30. rokoch 20. storo\u010dia si astron\u00f3movia v\u0161imli, \u017ee nie\u010do nesed\u00ed. Pozorovan\u00e9 pohyby galaxi\u00ed nazna\u010dovali, \u017ee v nich mus\u00ed by\u0165 viac hmoty, ne\u017e vid\u00edme. Inak by sa rozpadli. Toto „nie\u010do“ nazvali tmav\u00e1 hmota. Jej gravit\u00e1cia ovplyv\u0148uje pohyb hviezd a galaxi\u00ed, ale svetlo neodr\u00e1\u017ea ani nevy\u017earuje – je doslova nevidite\u013en\u00e1. Tmav\u00e1 hmota tvor\u00ed asi 27 % vesm\u00edru. Mo\u017eno si poviete, \u017ee 27 % nie je tak ve\u013ea. Ale zv\u00e1\u017ete toto: v\u0161etko, \u010do vid\u00edme – plan\u00e9ty, hviezdy, galaxie – tvor\u00ed len asi 5 % vesm\u00edru. Tmav\u00e1 hmota je teda 5-kr\u00e1t hojnej\u0161ia ne\u017e v\u0161etka vidite\u013en\u00e1 hmota.\u00a0Bez tmavej hmoty by galaxie nemohli dr\u017ea\u0165 pokope. Jej gravit\u00e1cia je to, \u010do umo\u017e\u0148uje hviezdam a plan\u00e9tam tvori\u0165 \u0161trukt\u00fary, v ak\u00fdch ich dnes vid\u00edme. Bez nej by vesm\u00edr vypadal \u00faplne inak – chaotick\u00fd a neusporiadan\u00fd. Aj ke\u010f ju nevid\u00edme, tmav\u00e1 hmota je k\u013e\u00fa\u010dom k pochopeniu vesm\u00edru. Vedeck\u00e9 t\u00edmy po celom svete sa sna\u017eia pr\u00eds\u0165 na to, z \u010doho je tmav\u00e1 hmota zlo\u017een\u00e1 a ako ju m\u00f4\u017eeme odhali\u0165. Mo\u017eno je to nov\u00fd druh \u010dast\u00edc, ktor\u00e9 e\u0161te nepozn\u00e1me. Alebo nie\u010do \u00faplne in\u00e9, \u010do obr\u00e1ti na\u0161e ch\u00e1panie fyziky naruby. Tmav\u00e1 hmota je d\u00f4kazom toho, \u017ee vesm\u00edr je pln\u00fd tajomstiev, ktor\u00e9 len \u010dakaj\u00fa na objavenie. A kto vie, mo\u017eno pr\u00e1ve ty bude\u0161 ten, kto odhal\u00ed jeho \u010fal\u0161ie tajomstv\u00e1.
