Was Our Universe Instantiated From A Superclass Universe?
If my memory isn't too disconnected, then quantum mechanics -- to how I remember best -- is a science describing the smallest of the smallest matters and realms in which everyday physics rules do not apply. Quantum mechanics would try to explain the inner working mechanism of the smallest realm that forms particles that are even smaller than electrons - and these particles form electrons and other similar matters. To this day, the inner working mechanism of the quantum realm isn't so clear, and so scientists sometimes can't explain such as why one particle can appear to be at two different places at the same time. Theoretically, scientists like to think every matter in the universe is a wave of some sort, and this wave of some sort allows any matter to appear to be in multiple places at once.
So, I imagine, you could too, that quantum mechanics could be like mechanics that allow our universe to import features from a superclass universe in which the inner working mechanisms of these features won't be revealed to the human mind since the human mind is boxed inside this universe. Perhaps by chance, the superclass universe is generous that it would allow a mechanism to allow the quantum mechanics to reveal the thread back to itself, but to find out this truth I surmise it won't be easy. Regardless, it's not so hard for any of us to imagine this universe of ours is an object which could have been born from a superclass object like how a programmer could create a new object from a superclass without knowing how the superclass was created. If this is true, we could easily tempt to believe that this universe of ours is just one object among many hundreds of billions of similar objects out there that were also instantiated from the superclass universe.
