I read both of your posts. No need to find further quotes. Slipspace isn't fractal on itself. It is only artificially fractal in very specific instances because of how the Forerunners manipulated it to suit their needs. IE, they shaped it into bubbles, or used it to create repeating patterns of infinite depth as your quotes indicate. Even then though, the artificially fractal nature of some of the Forerunners' slipspace technology is not explicitly stated to be why Halo's pulse can't enter slipspace. As I mentioned earlier, it's ambiguous to what effect - if at all - Halo has on raw slipspace.
