P\u0159eprava antihmoty i\u00a0tak p\u0159edstavuje mimo\u0159\u00e1dn\u00fd technick\u00fd v\u00fdkon.

Od zachycen\u00ed po rozv\u00e1\u017eku<\/p>\n

V\u011bdci antihmotu zkou\u0161\u00ed vyr\u00e1b\u011bt u\u017e od 50.\u00a0let minul\u00e9ho stolet\u00ed. Nejprve \u0161lo jen o\u00a0jednotliv\u00e9 \u010d\u00e1stice\u00a0\u2013 pozitrony a\u00a0antiprotony. Vytvo\u0159it opravdov\u00fd antiatom, by\u0165 ten nejjednodu\u0161\u0161\u00ed, antivod\u00edk, se poprv\u00e9 poda\u0159ilo a\u017e v\u00a0roce 1995\u00a0pr\u00e1v\u011b v\u00a0CERN.<\/p>\n

Zlomov\u00fdm momentem v\u00fdzkumu pak bylo zachycen\u00ed antihmoty. V\u00a0roce 2010\u00a0se t\u00fdmu projektu ALPHA<\/a> v\u00a0CERN poprv\u00e9 poda\u0159ilo udr\u017eet atomy antivod\u00edku v\u00a0magnetick\u00e9 pasti\u00a0\u2013 n\u011bkolik des\u00edtek atom\u016f na zlomky vte\u0159iny. O\u00a0rok pozd\u011bji ozn\u00e1mili<\/a>, \u017ee antivod\u00edk udr\u017eeli u\u017e tis\u00edc sekund, tedy asi \u0161estn\u00e1ct a\u00a0p\u016fl minuty. Sta\u010dilo to, aby se antiatomy \u201euklidnily\u201c a\u00a0sesk\u00e1kaly do z\u00e1kladn\u00edho stavu, v\u00a0n\u011bm\u017e je lze p\u0159esn\u011bji m\u011b\u0159it.<\/p>\n

Na podzim 2023\u00a0experiment ALPHA-g<\/a> poprv\u00e9 zm\u011b\u0159il, jak antivod\u00edk reaguje na gravitaci. Fyzici nechali zchlazen\u00e9 antiatomy unikat z\u00a0vertik\u00e1ln\u00ed pasti a\u00a0sledovali, kter\u00fdm sm\u011brem odl\u00e9taj\u00ed. V\u00fdsledek publikovan\u00fd v\u00a0Nature<\/a> potvrdil, \u017ee antihmota pad\u00e1 dol\u016f, stejn\u011b jako b\u011b\u017en\u00e1 hmota\u00a0\u2013 nikoli nahoru, jak ob\u010das spekulovaly okrajov\u00e9 teorie. Experiment ale zat\u00edm nedosahoval p\u0159esnosti pot\u0159ebn\u00e9 k\u00a0odhalen\u00ed subtiln\u00edch rozd\u00edl\u016f do jednoho procenta, kter\u00e9 teorie p\u0159ipou\u0161t\u011bj\u00ed.<\/p>\n

A letos v\u00a0b\u0159eznu antihmota poprv\u00e9 opustila m\u00edsto sv\u00e9ho vzniku. Za patn\u00e1ct let se v\u00fdzkum posunul od \u201eudr\u017eet neudr\u017eiteln\u00e9\u201c p\u0159es \u201ezm\u011b\u0159it nem\u011b\u0159iteln\u00e9\u201c k \u201ep\u0159ev\u00e9zt nep\u0159evoziteln\u00e9\u201c.<\/p>\n
