Trancendental Punctuation to fill the Gap-Toothed Galaxies

It is a matter of some doubt what constitutes the vast amount of 'dark matter' that is believed to fill the otherwise totally inconceivable interstellar spaces. I imagine that dark matter consists of an almost infinite number of punctuation marks. Interstellar punctuation to clarify the grammar of the universe. And which punctuation marks? Given what I understand about the known universe, my bet would be on quotation marks, that being the most ironic.
