Vex and multiverses

What is a Dream? What is an illusion? What is real? Am I real? In the Ghost Fragment: Vex 1-3, Esi, Sundaresh, and Shim research a captured vex. They figure out the vex had made simulated world inside itself that had predicted everything that the doctors were doing at the time, all based on what it had seen. The Vex could predict the future. They decide to bring a Warmind, something too complicated for the vex to predict and they were able to save themselves inside the Vex's simulated world. One question they had was if they were the simulation. Could the Vex then hurt them? My theory is that the worlds that live inside the Vex are not just simulations, but entire universes. One theory of time says that there are infinity many universes based on possible choices. If you had to make a choice between eating a candy bar or an apple, two or more universes can be made. The Vex simulate entire universes inside their minds, based on what is known to them(Vex Gatelord Qodron sees only its Glorious future). When the unknown is encounter to them, those universes diverge into multiple universes all based on the possibilities they can see. Now what if the Vex can choose which universe is real. The choices you would make are bound to the Vex. This what I believe is the true power of Vault of Glass. The Oracles for see a possible future, ones in which you and your fireteam make mistakes leading to their deaths, while Atheon and the Templar provide the power necessary to make those universes a reality. Perhaps Atheon is from another universe that has foreseen the Vault of Glass. Are we just a simulation of Atheon or is Atheon a simulation of the Vault of Glass or are both real in their respective universes and Atheon is just passing through a window. Here's another theory. What if those Vex structure are simulating an entire universe, one in which the Vex have achieved their ultimate goal. Is the exo stranger from that universe. Can they bring that universe into this reality. One thing is certain about the Vex, they can't predict the unknown. There is nothing more mysterious then the Travel and Darkness. Why are Vex losing on Mars. Maybe they want to what the Cabal are truly capable of so they can see a future in the cabal ultimately lose and take the correct actions to achieve that future. Don't lose faith Guardians. You are a wild card that the Vex can't predict. Their is future where you are victorious. Make your own fate.
