Nu putem vedea nimic din ceea ce s-a \u00eent\u00e2mplat \u00een primii 300 000 de ani ai Universului. Oamenii de \u0219tiin\u021b\u0103 \u00eencearc\u0103 s\u0103-\u0219i fac\u0103 o idee pe baza cuno\u0219tin\u021belor lor despre particulele atomice \u0219i a modelelor computerizate.<\/p>\n<\/div>\n

Singura dovad\u0103 direct\u0103 a Big Bang-ului \u00een sine este o str\u0103lucire slab\u0103 \u00een spa\u021biu. Navele spa\u021biale \u0219i telescoapele montate pe baloane percep acest fenomen ca un model neuniform de gaz u\u0219or mai cald \u0219i mai rece care ne \u00eenconjoar\u0103. Aceste undula\u021bii indic\u0103, de asemenea, locurile \u00een care norii de hidrogen erau pu\u021bin mai densi.<\/p>\n

Pe m\u0103sur\u0103 ce au trecut milioane de ani, zonele dense au atras materie datorit\u0103 gravita\u021biei lor mai puternice. \u00cen cele din urm\u0103, la aproximativ 100 de milioane de ani dup\u0103 Big Bang, gazul a devenit suficient de fierbinte \u0219i de dens pentru ca primele stele s\u0103 se formeze.<\/p>\n

Noile stele se n\u0103\u0219teau \u00eentr-un ritm de 10 ori mai rapid dec\u00e2t \u00een Universul actual. Marii roiuri de stele s-au transformat \u00een scurt timp \u00een primele galaxii.<\/p>\n

Cea mai nou\u0103 camer\u0103 a telescopului Hubble surprinde un focar de formare stelar\u0103<\/figcaption><\/figure>\n

Telescopul spa\u021bial Hubble \u0219i puternicele telescoape terestre \u00eencep acum s\u0103 descopere galaxii care s-au format la aproximativ un miliard de ani dup\u0103 Big Bang. Aceste galaxii mici se aflau mult mai aproape unele de altele dec\u00e2t galaxiile de ast\u0103zi. Coliziunile erau frecvente. Precum dou\u0103 fl\u0103c\u0103ri care se \u00eendreapt\u0103 una spre cealalt\u0103, ele s-au contopit form\u00e2nd galaxii mai mari. Galaxia noastr\u0103, Calea Lactee, s-a format \u00een acest fel.<\/p>","protected":false},"excerpt":{"rendered":"
