Nem\u016f\u017eeme vid\u011bt nic z toho, co se odehr\u00e1lo b\u011bhem prvn\u00edch 300 000 let existence vesm\u00edru. V\u011bdci se to sna\u017e\u00ed odvodit na z\u00e1klad\u011b sv\u00fdch znalost\u00ed o atomov\u00fdch \u010d\u00e1stic\u00edch a pomoc\u00ed po\u010d\u00edta\u010dov\u00fdch model\u016f.<\/p>\n<\/div>\n

Jedin\u00fdm p\u0159\u00edm\u00fdm d\u016fkazem samotn\u00e9ho Velk\u00e9ho t\u0159esku je slab\u00e9 z\u00e1\u0159en\u00ed ve vesm\u00edru. Kosmick\u00e9 sondy a dalekohledy na bal\u00f3nech toto z\u00e1\u0159en\u00ed vn\u00edmaj\u00ed jako nerovnom\u011brn\u00fd vzor m\u00edrn\u011b teplej\u0161\u00edho a chladn\u011bj\u0161\u00edho plynu v\u0161ude kolem n\u00e1s. Tyto vlny tak\u00e9 ukazuj\u00ed, kde byly mraky vod\u00edku o n\u011bco hust\u0161\u00ed.<\/p>\n

V pr\u016fb\u011bhu milion\u016f let hust\u0161\u00ed oblasti p\u0159itahovaly hmotu, proto\u017ee m\u011bly v\u011bt\u0161\u00ed gravita\u010dn\u00ed s\u00edlu. Nakonec, asi 100 milion\u016f let po Velk\u00e9m t\u0159esku, se plyn zah\u0159\u00e1l a zhoustl natolik, \u017ee se mohly vytvo\u0159it prvn\u00ed hv\u011bzdy.<\/p>\n

Nov\u00e9 hv\u011bzdy vznikaly desetkr\u00e1t rychleji ne\u017e v dne\u0161n\u00edm vesm\u00edru. Z rozs\u00e1hl\u00fdch hv\u011bzdn\u00fdch shluk\u016f se brzy staly prvn\u00ed galaxie.<\/p>\n

Tyto mal\u00e9 galaxie se nach\u00e1zely mnohem bl\u00ed\u017ee u sebe ne\u017e galaxie dnes. Sr\u00e1\u017eky byly b\u011b\u017en\u00e9.
