"Each mirror is a world of it's own," Joe explains.
"Joe, that's bulls***! Mirrors are just mirrors!" Rita proclaims.
Joe proceeds to lay out the following~
- Law of Rotation: For each one orientation of a mirror (rotated spherically or in 3D space) there is exactly one universe perfectly symmetrical to our own.
- Law of Quantity: There are infinite orientations possible in a sphere, so there are infinite universes parallel to our own. (Sidenote: Why not just have one mirror universe? Why do we need infinite parallel ones? Because moving an entire universe when you pick up a mirror seems like a lot more work then connecting to a bunch of other ones)
- Law of Non-Uniqueness: Every universe began at the same time and progressed in the exact same way, with the exception of being "flipped" as we observe in a reflection. That means we are nothing special.
- Law of Boundaries: The line of symmetry in each case is defined by the mirror itself.
- Law of Congruent Copies: Changing the orientation of a mirror links to another exact replica of that mirror universe - they are all congruent to each other through transitivity
- Law of Interaction: We cannot exchange matter into these universes because for every one particle that attempts to cross the threshhold, exactly one congruent particle meets it at the barrier.
- Law of Weak Reflectional Attraction: A weak force along the mirror accounts for substances "stuck" to each other across the threshhold. This is why mirrors can be dirty: the boundary has a slight pull that makes dirt, etc stay on the plane of the mirror instead of falling as if there was simply air.
- Law of Rigidity and Flatness: Boundaries such as funhouse mirrors or reflections in water serve only as distorted windows; they must be flat and rigid to allow actual interaction.
- Law of Heat Transfer: The medium of the mirror (metal, etc) moderates heat transfer, which is why you don't feel immediate warmth when you touch a mirror with your hand.
- Law of Medium Maintenance: That which would break the mirror surface due to pressure or momentum will do so before trying to pass through. Each new shard is its own boundary.
"Joe," says Rita, "Your 'theory' doesn't account for this."
Rita picks up a household object and demonstrates why mirrors are simple reflections of light, and nothing more.
Her demonstration produces results that would be different if there were multiple, congruent universes bound by mirrors (for example hitting the mirror with something that should have gone through if there were actually an alternative universe on the other side)
