Aceasta dovad\u0103 a venit 2 decenii mai t\u00e2rziu \u00een anul 1965 c\u00e2nd Penzias \u0219i Wilson descopereau prin telescoape performante ecourile exploziei primordiale, adic\u0103 a conceptului de Big Bang<\/em> \u00een forma pe care o \u0219tim ast\u0103zi.\u00a0Lema\u00eetre \u00eensu\u0219i \u0219i-a descris teoria sa ca „oul cosmic care explodeaz\u0103 \u00een momentul crea\u021biei<\/em>„. Aceasta a devenit mai bine cunoscut\u0103 sub numele de „teoria Big Bang”, un termen peiorativ inventat de Fred Hoyle. Cu toate acestea, Lema\u00eetre, ca preot, credea c\u0103 Universul \u0219i deci \u0219i P\u0103m\u00e2ntul au fost create de c\u0103tre Dumnezeu.<\/p>\n
