So today let's talk about the vex. Time travel huh? How do they do it? And better yet, how do they do it without any paradoxes?[quote]for the vex, there is no paradox. ~Preadyth[/quote] We know the vex are able to reach beyond the veil and beyond the veil may be a a sort of void that is separate of time. We can tell this from the FWC device as the device was a golden age experiment to try and mimic the vex portal system. When inside the device people were able to see timelines, but there was no way of telling which one was ours except for obvious deviations. The device, however, can drive people mad. Human minds are too weak for the device and so the FWC, as of the end of RECORD 343-CHASM-789, were going to try using a machine. So with that knowledge in mind let's look back at the vex. Their portal system can reach beyond the veil. A place that, can safely be assumed, is separate of time. Now for a twist. I don't think the vex time travel. Now if you remember from the book of sorrows, Crota (while helping his sisters with an experiment) cut open a "new wound," into a "new space". From this wound the vex came out. Now consider this. What if Crota accidentally cut into a pocket beyond the veil? One that just so happened to contain a bunch of vex. So what I bet the vex do in order to retain information about the future and change the past without causing a paradox is, hide in a pocket beyond the veil. When the vex get to a point in a timeline where critical failure is imminent. They pack up all the knowledge they had in relation to major events that happened up to then and give results on tests that failed or succeeded and ship it out with a collection of precursors. The precursors then retreat safely to a pocket beyond the veil and wait for Crota in the next timeline to screw up the experiment and open a hole into the next timeline. However with each timeline there's bound to be a few differences so they have to scan to see what's different and they simulate things to make absolutely sure everything goes according to plan. [spoiler]for an example. In one timeline, they managed to survive until the taken king arrives, then critical failure was achieved when a majority of vault of glass assets were taken. They made note of that for the next timeline and captured a guardian to lure the light into the vault to kill off the taken. That guardian was Preadyth.[/spoiler] Rinse and repeat until they eventually weave themselves into reality and have an emperor of all outcomes. Now I hear someone crying out. [b]BUT THE VAULT! THAT'S A PLACE WHERE THE PAST, PRESENT, AND FUTURE CAN INTERACT![/b]. That it is, that it is. However the places those portals lead to are isolated just like the vault itself. They can interact without a paradox because of this isolation. So where I have no doubt we're time traveling in the vault, it doesn't affect anything because we're just moving to another isolated space. So to sum this up. Think of the movie "edge of tomorrow". That's basically what the vex are doing. Live, test, record, hide, repeat. They don't time travel, they hop timelines. No paradoxes, no time loops, and just a little more victory each hop.
