A legt\u00f6bb csillag\u00e1sz \u00fagy v\u00e9li, hogy az Univerzum k\u00f6r\u00fclbel\u00fcl 14 milli\u00e1rd \u00e9vvel ezel\u0151tt egy Nagy Bummmal j\u00f6tt l\u00e9tre. Abban az id\u0151ben az eg\u00e9sz Univerzum egy olyan bubor\u00e9kban volt, amely t\u00f6bb ezerrel kisebb volt, mint egy t\u0171fej. Forr\u00f3bb \u00e9s s\u0171r\u0171bb volt, mint b\u00e1rmi, amit el tudunk k\u00e9pzelni.<\/p>\n<\/div>\n

Azt\u00e1n hirtelen felrobbant. Megsz\u00fcletett az \u00e1ltalunk ismert Vil\u00e1gegyetem. Az id\u0151, a t\u00e9r \u00e9s az anyag mind az \u0150srobban\u00e1ssal kezd\u0151d\u00f6tt. Egy m\u00e1sodperc t\u00f6red\u00e9ke alatt a Vil\u00e1gegyetem egy atomot is kisebb m\u00e9retr\u0151l egy galaxist is meghalad\u00f3 m\u00e9ret\u0171re n\u0151tt. \u00c9s elk\u00e9peszt\u0151 sebess\u00e9ggel folytatta a n\u00f6veked\u00e9st. Ma is folyamatosan t\u00e1gul.<\/p>\n

Ahogy az Univerzum t\u00e1gult \u00e9s leh\u0171lt, az energia anyag- \u00e9s antianyag-r\u00e9szecsk\u00e9kk\u00e9 alakult \u00e1t. Ez a k\u00e9t egym\u00e1ssal ellent\u00e9tes r\u00e9szecsket\u00edpus nagyr\u00e9szt megsemmis\u00edtette egym\u00e1st. De egy kis mennyis\u00e9g\u0171 anyag megmaradt. Az Univerzum kialakul\u00e1s\u00e1nak els\u0151 m\u00e1sodperc\u00e9ben kezdtek kialakulni a protonok \u00e9s neutronok nev\u0171, stabilabb r\u00e9szecsk\u00e9k.<\/p>\n

A k\u00f6vetkez\u0151 h\u00e1rom perc alatt a h\u0151m\u00e9rs\u00e9klet 1 milli\u00e1rd Celsius-fok al\u00e1 s\u00fcllyedt. Ekkor m\u00e1r el\u00e9g hideg volt ahhoz, hogy a protonok \u00e9s a neutronok \u00f6ssze\u00e1lljanak, \u00e9s hidrog\u00e9n- \u00e9s h\u00e9liumatomokat k\u00e9pezzenek.<\/p>\n

300 000 \u00e9v eltelt\u00e9vel az Univerzum h\u0151m\u00e9rs\u00e9klete k\u00f6r\u00fclbel\u00fcl 3000 fokra cs\u00f6kkent. Az atommagok v\u00e9gre elektronokat tudtak magukhoz vonzani, \u00e9s \u00edgy atomokat alkottak. Az Univerzumot hidrog\u00e9n- \u00e9s h\u00e9liumg\u00e1zfelh\u0151k t\u00f6lt\u00f6tt\u00e9k be.<\/p>","protected":false},"excerpt":{"rendered":"
