[ WP ] Unknown to us mirrors actually are just windows into an alternate dimension that is exactly the same except right and left are reversed . Until one day something throws the mirror dimension out of sync ...

“ You see… us and them, we inhabit two worlds set into motion with the exact same starting conditions. ” 
 
 The Professor has my full attention. 
 
 “ Back in the days, the looking glass used to render a mirror image of our world. Us, and them too, used to conveniently call it the ‘ mirror ’. We used to look into the mirror to check if there is something in our teeth, as that would always show a real-time reflection of ourselves. ” 
 
 Yes, we are all familiar with that little piece of history. I have always wondered how the world then must have been, with these mirrors. Those intriguing mirrors in the old movies that always captured my attention. 
 
 “ Then all of a sudden, the mirrors stopped behaving that way. In the beginning, everyone was freaked out! Them too. They must have been. Then, we started communicating to the other side by writing on these signs and holding them up to the looking glass. ” 
 
 Those days must have been wildly exciting for everyone. It ’ s like the laws of the universe has just changed and God has given us, all of us, a hint into his creation which now seems even more elaborate than previously thought. 
 
 “ You see… when two universes mirrored each other for all that time, just because they have matching initial conditions, that fact alone, has huge implications. It means that our destiny, is predetermined, and our free will is nothing but a mere perception. But when things fell out of sync! What does that mean? We thought one of our worlds must have cracked the code and escaped its predetermined destiny! ” 
 
 Yes, and it was at that time… that all the looking glasses in our world stopped rendering anything. What an ironic name, when all we look at through this looking glass is the darkest of darks, as if you are taking a peek into the deepest mysteries of the universe.
