Not a serious lore/theory discussion thread to post some wacky Destiny conspiracy theories such as “Zavala and Ikora keeping the Hunter vanguard vacant so they can prop up Shaw Hawn as a Hunter figurehead” etc etc
The game is trying to show you the shape of the perfect paradox.
One dreaming, the other existing within the dream. How to define consciousness in a world built on definition, all the things you would have to achieve. Creating freewill by creating your opposite and opposing force; then Murphy's law or as the movie title would suggest "Everything, Everywhere, All At Once".
When an unstoppable force meets an immovable object, I allow them to exist at the same moment in the same position.
