I still stand by my claim. In fact, the IsoDidact revealed that Forerunners didn't fully understand how Halo would effect slipspace - if at all, so they resorted to performing calculations to determine when to fire Halo at a point where the pulse would hit virtually all Flood and Precursor forces out of slipspace. Assuming some did survive Halo's pulse in slipspace, they would still be dead. The Flood would exist in a galaxy without substantial life, and would die off, while the Precursor star roads would be rendered inactive, as they only activated in the presence of Flood in the final years of the war. I also have to apologize. I want to support my claims with quotes, but it isn't really feasible to store my library of Halo lore in my dorm room.
