A love so profound. Across worlds in what way? — Grre
It requires a vague understanding of quantum dynamics and entanglement. But, let me break this down.
There's something esoteric about consciousness, no? I mean, you studied it? Now, let's assume that we have two beings across possible worlds, that just won't accept anything less than perfection in love. They just want to find the best possible candidate across possible worlds, that would allow them to do so.
Breaking down the sci-fi part, there's a plane of existence, (think of it as overcoming a mountain, though it instead of over it), that allows these two beings to meet, across the set of all possible worlds. I don't quite understand this plane of existence that would allow transworld connectivity/communion; but, let's just assume it's true, no? I really don't understand on what basis this would be true; but, you've dabbled into psychs, right? Know where this is going?
