I was riveted as she explained how it is totally invisible to us (or put more scientifically, undetectable by any means we have), but it is evidently there. You can see that in the gravitational pull of galaxies, and most strikingly in the incredible gravitational lensing which I won't attempt to explain (follow the link for stunning pics).
Another thing that stuck in the mind was the fact that ordinary (i.e. visible) matter is estimated to make up only 5% of the mass of the universe. That made me think irresistibly of Being (Wujûd, وجود) and Non-Being (3adam, عدم), manifest and unmanifest, two concepts I have worked with before but that were now presenting themselves as a pair. This piece is a reflection on their relationship, inspired by the current state of science's understanding of dark matter.
At the centre is Being, occupying a tiny area of the canvas which is otherwise filled with Non-Being. Our friend mentioned that "dark matter" was an unfortunate name so I wanted to move away from associating it with black, and as the paper equivalent of the black emptiness of space is whiteness, I decided to use cut paper, white on white. The word stretched into a green ring can just be guessed: it is just a glimpse, similar to what we observe through gravitational lensing, of what lies much further out, beyond the Nothingness — what Sufis call Absolute Truth.
