Our world was created in co-operation between these three proto-forces. Between Múspellheimr (the stars) and Niflheimr (the frozen matter in space) there was Gínungagap (the void). The universe was resting. It was inactive. It was in a state of complete balance.Everyone knows that Ginnungagap was the boundary between Niflheim (the land of frost) and Muspelheim (the land of fire), where the great icecow Audhumla, who belonged to the giant Ymir, licked Buri out of the ice. And Buri was the father of Borr, who mated with Bestla (a frost giant), to beget the Æsir: Odin, Vili and Ve.
The universe woke after this rest of Freyr. Óðinn's force threw the mass out in all directions again. The stars began to melt the frozen matter in space when they met each other, out there in Gínungagap; in the void.
In Múspellheimr, there was the divine bosom, the explosion which gives new life to the universe. In Niflheimr, there was the resting divine thought, frozen. The ice melted and it became active again.
In Ragnarök, the opposite forces cancel each other out until only one force is left standing. Since the gravitational pull is constant, while the explosion only works over a limited time, gravity will always win. It will always, after a period of time, force the mass of universe together again.
Then the Aesir killed Ymir (whose blood poured forth and destroyed all but two of the jotunn), and used his flesh to make the earth, his bones to make the mountains, and his teeth and bone fragments became stones; and they used his skull to become the arch of the sky.
(See? They recycled.)
Is Varg just insane? The Allfather will destroy him for this heresy! And I can go on at length about how Odin is a metaphor for death, not some stupid proto-force of expansion/explosion.
(That whole question of Varg's sanity is actually a valid concern. I mean, he did do 16 years for murder and arson. On the other hand, he's descended from the Vikings, so burning down churches and slaughtering innocents might just be a genetic imperative for him.)
The whole skycow story makes as much sense as "God was bored, and took a week to make the earth, but we don't know how or what he built it out of," if you think about it.
I wonder if the story of Ymir's blood is where we get these profane bastardizations like "the Great Flood"?
