Vex Time Travel Explanation and Speculation In the Multiverse theory, every decision, whether you are rejecting one thing or twelve, creates an alternate timeline where you did, in fact, make a decision, instead of the one you think you made. To clear this up, think of it like this, you walk into an ice cream store, which sells three flavors, chocolate, vanilla, and strawberry. If you choose chocolate, in your timeline, you will purchase and eat the chocolate ice cream, however, this also creates two alternate timelines in which you choose vanilla and strawberry respectively. Logically, time travel must work the same way, yes? If you travel back in time and change something, then there is now two timelines, one where you change something, and another where nothing is changed. Let's go back to our analogy from before. So, your walking down the street, enjoying your ice cream, when suddenly, a crazy British guy jumps out of a police call box and slaps the ice cream out of your hand. There is now a timeline where he slaps the ice cream out of your hand, and one where he does not. From our ice cream analogy, this theory seems a bit small and unnecessary, but if you apply it to a larger situation, say, your birth, it becomes much more interesting. There was a small chance for the one specific sperm to fertilize your mothers egg, so say, another sperm fertilizes it by chance, and you are born a completely different person, and it doesn't end there. (Which is crazy, considering that already changed most of your, and many others lives, and, that is over 1000 timelines!) Now, the chances for complications at birth are higher when the mother drinks or smokes, and, in the alternate timeline, your mother may have chosen to do one of those things, and at this point, your self in our timeline and your self in the metaphorical timeline are literally different people. Now, assuming you were even born, your parents and grandparents, and great grandparents and so on, have now effected your life by altering their own timelines, putting them in trillions of different social, economic, political, and geographic situations, that you never had control over. Then, every decision you make after you are born, makes more timelines, and, in the grand scheme of things, sounds like a lot of hoopla, and yes I know what your asking. "But Turtle, what does this have to do with the Vex?" "But Turtle, what is up with the Doctor Who reference?" "But Turtle, why do you sound like the crazy guy on the history channel with the Jew fro that says aliens?" Some of these questions and more, answered, lower down this page So, back to the theory. I have already made a theory that touches on the origin of the Vex, but nothing on how the Vex work. according to the theory, the have their own dimension, where they can base operations and breach holes into other realities and times. We can dub this place, the "HubWorld" seeing as it is the center of something big. Now, every hole they breach into another reality, another reality is made because of this decision. You can see where this is going. Every time the Vex change anything, it changes an infinite amount of other things, blah blah blah, there is a lot of dimensions, we get it. Now, this brings up the paradox argument, which I totally agree with, but, it is more of a pesky road block, rather than a loopty loop. Now this paradox is where the HubWorld comes in. The Vex can make dimensions, so, they make Interdimensional portals, to guard their HubWorld. Then, they can use these portals, or "Gates" if you will, to enter realities linked to them, so in other words, the Vex have made a dimensional Hierarchy, where larger worlds under Vex control, in turn control smaller worlds with life, possibility, and chance. Also, I will now refer to any of these smaller worlds as "SubWorlds" So now the questions are- "So why do they need these gates?" "Ummm, we didn't really solve the paradox, did we?" and- "Is my head supposed to hurt?" The answer to the last one is yes. The answer to the next few are coming up. The gates are required for protection, because if the HubWorld is destroyed, so is everything else the Vex relies on. The Gates act as protection from pesky intruders using the gates' breaches in time, space and dimension as there own personal taxi service. The answer to the paradox question? There wasn't one in the first place. The reason the light is so much of a threat to the Vex is because of the number of dimensions there are that have soldiers of the light in them. The simple solution is to simply close the portals into those SubWorlds. Unfortunately you can't exactly do that in worlds that are directly linked to a gate, such as ours. The vault of glass, isn't just a vault. It's a gate. Beating Atheon isn't the reason Kabr went to the vault, it was to open us up to the Vex HubWorld, and we were just too foolish to see it. Atheon is just the guard, and we need to do more research into the vault to determine how to activate and use it. We just went over a lot, let's have a recap -The Vault is a Gate -Our SubWorld is lucky enough to have a Gate -The Vex can solve their paradox by effectively locking Subworlds out of the system. -The Only way to stop the Vex is to enter their HubWorld Alright, last topic, the HubWorld. Your first thought about the HubWorld may be to destroy it, but there would be dire consequences. Closing all those portals abruptly at the same time could make all of spacetime collapse, and, that is bad, because we happen to live there. The only way to stop the Vex is to capture the Vex HubWorld, and use it against them, but be careful guardians, because power that strong could corrupt even the brightest of soldiers, and if put in the wrong hands, could destroy everything.
