Wi\u0119kszo\u015b\u0107 astronom\u00f3w uwa\u017ca, \u017ce Wszech\u015bwiat powsta\u0142 w wyniku Wielkiego Wybuchu oko\u0142o 14 miliard\u00f3w lat temu. W tamtym czasie ca\u0142y Wszech\u015bwiat znajdowa\u0142 si\u0119 wewn\u0105trz ba\u0144ki, kt\u00f3ra by\u0142a tysi\u0105ce razy mniejsza od g\u0142\u00f3wki szpilki. By\u0142 on gor\u0119tszy i g\u0119stszy ni\u017c cokolwiek, co mo\u017cemy sobie wyobrazi\u0107.<\/p>\n<\/div>\n

Wtedy nagle dosz\u0142o do eksplozji. Powsta\u0142 znany nam Wszech\u015bwiat. Czas, przestrze\u0144 i materia powsta\u0142y wraz z Wielkim Wybuchem. W u\u0142amku sekundy Wszech\u015bwiat rozr\u00f3s\u0142 si\u0119 z rozmiar\u00f3w mniejszych ni\u017c pojedynczy atom do rozmiar\u00f3w wi\u0119kszych ni\u017c galaktyka. I nadal rozrasta\u0142 si\u0119 w niesamowitym tempie. Rozszerza si\u0119 do dzi\u015b.<\/p>\n

W miar\u0119 jak Wszech\u015bwiat rozszerza\u0142 si\u0119 i och\u0142adza\u0142, energia przekszta\u0142ci\u0142a si\u0119 w cz\u0105stki materii i antymaterii. Te dwa przeciwstawne rodzaje cz\u0105stek w znacznej mierze wzajemnie si\u0119 zniszczy\u0142y. Jednak cz\u0119\u015b\u0107 materii przetrwa\u0142a. Bardziej stabilne cz\u0105stki, zwane protonami i neutronami, zacz\u0119\u0142y powstawa\u0107, gdy Wszech\u015bwiat mia\u0142 jedn\u0105 sekund\u0119.<\/p>\n

W ci\u0105gu nast\u0119pnych trzech minut temperatura spad\u0142a poni\u017cej 1 miliarda stopni Celsjusza. By\u0142o ju\u017c wystarczaj\u0105co ch\u0142odno, by protony i neutrony mog\u0142y si\u0119 po\u0142\u0105czy\u0107, tworz\u0105c j\u0105dra wodoru i helu.<\/p>\n

Po up\u0142ywie 300 000 lat temperatura Wszech\u015bwiata spad\u0142a do oko\u0142o 3000 stopni. J\u0105dra atomowe mog\u0142y wreszcie przyci\u0105ga\u0107 elektrony, tworz\u0105c atomy. Wszech\u015bwiat wype\u0142ni\u0142 si\u0119 chmurami wodoru i helu w stanie gazowym.<\/p>","protected":false},"excerpt":{"rendered":"
