Bölverkur, name of Óðinn, means he who perforates, he who makes holes, he who splits up, he who penetrates the so-called matter.
He uses worm-holes, drilled by Rati the rat.
This is how we expand to infinity,

Óðinn simply takes on the guise of a worm: bregðst í ormslíki.
We can easily do that.

Worm-holes (physics). We all can easily use them.
