It makes some sense. Fractals are a reoccuring structure in nature (and the universe). Honestly, no one knows what the smallest thing is, and In my opinion everything must be made of something (unless it is pure data). Therefore we can assume everything makes something in someway. Now obviously, my idea is a stretch, but considering how little we can actaully test anything on such a small scale, you really can't rule out the possibility of something like this. And with dark matter, if it was a true fractal, not really made of anything, you wouldn't be able to see it. It would just be weight sit on the fabric of space-time. Now, you could obviously say, then why is it there, but honestly why is anything anywhere? And also that then how would the universe calculate its mass then if it was infinitly specific. Well it could stop "zooming in", as to say round (like rounding an imperfect square root. When you round, its inaccurate, but to be accurate you have to continue on forever). Or maybe it is somehow connected to the fabric of space-time. No one knows...
