I would imagine Halo has a maximum pulse range, that after going on for so long, the energy ceases to be enough to do any more significant damage.reaperdude42 wrote: "why does the aray only effect one galaxy" if it is some kind of galactic death ray that gets fired then it wouldnt stop when it reached the edge of the galaxy it would just keep going. How did the forerunnrs keep the wipe out to just one galaxy.
I would also like to point out that the fact that there was a 100000 years between firings and the fact that the galaxy 100000 light years across seems like to much of a coincidence to me...
Heck, maybe it keeps going throughout the entire cosmos. That would suck.
And the 100,000 re-ocourance is a rather tricky coincidence... hmm...
