Majoritatea astronomilor consider\u0103 c\u0103 Universul a luat na\u0219tere \u00een urma unui Big Bang, \u00een urm\u0103 cu aproximativ 14 miliarde de ani. La acea vreme, \u00eentregul Univers se afla \u00een interiorul unei bule de mii de ori mai mic\u0103 dec\u00e2t capul unui ac. Era mai fierbinte \u0219i mai dens dec\u00e2t orice ne-am putea imagina.<\/p>\n<\/div>\n

Apoi, dintr-odat\u0103, a explodat. S-a n\u0103scut Universul pe care \u00eel cunoa\u0219tem. Timpul, spa\u021biul \u0219i materia au luat na\u0219tere odat\u0103 cu Big Bang-ul. \u00centr-o frac\u021biune de secund\u0103, Universul a crescut de la o dimensiune mai mic\u0103 dec\u00e2t un singur atom la una mai mare dec\u00e2t o galaxie. \u0218i a continuat s\u0103 creasc\u0103 \u00eentr-un ritm fantastic. Se extinde \u0219i ast\u0103zi.<\/p>\n

Pe m\u0103sur\u0103 ce Universul s-a extins \u0219i s-a r\u0103cit, energia s-a transformat \u00een particule de materie \u0219i antimaterie. Aceste dou\u0103 tipuri opuse de particule s-au anihilat \u00een mare parte reciproc. Totu\u0219i, o parte din materie a supravie\u021buit. Particule mai stabile, numite protoni \u0219i neutroni, au \u00eenceput s\u0103 se formeze c\u00e2nd Universul avea o v\u00e2rst\u0103 de o secund\u0103.<\/p>\n

\u00cen urm\u0103toarele trei minute, temperatura a sc\u0103zut sub 1 miliard de grade Celsius. Acum era suficient de rece pentru ca protonii \u0219i neutronii s\u0103 se uneasc\u0103, form\u00e2nd nuclee de hidrogen \u0219i heliu.<\/p>\n

Dup\u0103 300 000 de ani, Universul se r\u0103cise p\u00e2n\u0103 la aproximativ 3000 de grade. Nucleele atomice au putut \u00een sf\u00e2r\u0219it s\u0103 capteze electroni pentru a forma atomi. Universul s-a umplut de nori de hidrogen \u0219i heliu \u00een stare gazoas\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
