Cosmogonies are also called creation myths.

宇宙也称为创造神话。

There are two modes for the evolution of the large-scale structures in the universe: small to large and large to small cosmogonies, which would be alternately, but progressively, adopted.

对这些结构的形成可以有不同的解释，如引力形成、爆炸形成及宇宙弦等．一般广泛接受的宇宙结构的演化是由于引力的相互作用。
