Takrat je bilo celotno vesolje zaprto v mehur\u010dek, ki je bil tiso\u010dkrat manj\u0161i od glave \u0161ivanke. Bilo je vro\u010deje in gostej\u0161e, kot si sploh lahko predstavljamo.<\/p>\n<\/div>\n<p>Nato je nenadoma eksplodiralo. Rodilo se je vesolje, kot ga poznamo. \u010cas, prostor in snov so se vsi za\u010deli z velikim pokom. V del\u010dku sekunde se je vesolje raz\u0161irilo iz velikosti, manj\u0161e od enega samega atoma, na velikost, ve\u010djo od galaksije. In \u0161e naprej se je \u0161irilo z neverjetno hitrostjo. \u0160e danes se \u0161iri.<\/p>\n<p>Ko se je vesolje \u0161irilo in ohlajalo, se je energija spremenila v delce snovi in protisnovi. Ti dve nasprotni vrsti delcev sta se v veliki meri medsebojno uni\u010dili. Vendar je nekaj snovi pre\u017eivelo. Ko je bilo vesolje staro eno sekundo, so se za\u010deli oblikovati stabilnej\u0161i delci, imenovani protoni in nevtroni.<\/p>\n<p>V naslednjih treh minutah se je temperatura spustila pod 1 milijardo stopinj Celzija. Zdaj je bilo dovolj hladno, da so se protoni in nevtroni zdru\u017eili ter tvorili jedra vodika in helija.<\/p>\n<p>Po 300 000 letih se je vesolje ohladilo na pribli\u017eno 3000 stopinj. Atomski jedri so kon\u010dno lahko zajeli elektroni in tako oblikovali atome. Vesolje se je napolnilo z oblaki vodika in helija.<\/p>","protected":false},"excerpt":{"rendered":"<p>Most astronomers believe the Universe began in a Big Bang about 14 billion years ago.
