"Cosmogony" is a song by Icelandic artist Björk, released as the second single from her seventh album Biophilia.

In January 2011, when the app Solar System by Touch Press was released, it was accompanied by an instrumental introduction written by Björk.

"Cosmogony" is a calm and warm song, marking the link between the previous Björk project, Volta and Biophilia, using distorted brass, but in a much more intimate soft way.

So it's all about copper and rotating things and harmony and equilibrium and the universe and where there’ s a place for every little thing and we're all taken care of.Björk also considers the song as some kind of joke, branding the Big Bang theory as a 20th-century creation myth: I guess after watching documentaries about string theory, [the song] was sort of a personal joke [...] Big Bang [is] 20th Century and string theory [is] so 21st Century [...] I guess all creation myths at the time of their making were science.

Björk debuted all songs from Biophilia during a series of performances at the Manchester International Festival in England between 27 June and 16 July 2011.
