IN THE BEGINNING, packing problemed every single base plank level, cube shaped, magnetized, RGB, Plank bucky cube into as tight of shape as they can form magnetically leaving no empty spaces that can be moved into without a force to cause the cubes to separate magnetically.

If no cube has any empty locations, free from other cubes, that it can move into, and is magnetically locked together into a singular magnetic object/structure without any gaps at all, and is unable to detach and break off, then there exists no time.
Time in our universe is the movement of 1 magnetized, RGB, base Plank length cube into 1 empty cube location, Front/Back, Left/Right, Up/Down, and the ratios thereof (much like a blackhole, the Universes parts, broken down to base Plank sized cubes, packed together as tightly as possible leaving no empty cube spaces, no time = no movement).

So, in order to get to the point where we can actually separate the singularity blocks magnetically from one another, we have to create our circle in essence, or close our loop.
We connect the end of the build, to the beginning through a circuit.
So the build itself is connected to itself from the beginning solid blocks, to the end of the universes built block arrangement, but also from the end of the build, then back to the beginning separately.
Creating our circuit.
The past then affects the future, and the future affects the past.

The wave function collapse, in essence.
