Unfortunately of course such hypotheses are extraordinarily difficult to actually test. However intuitively I do kind of like where you’re coming from. I’ve always been fascinated by how everything that we conceptually are aware of has a sorta polar opposite that we kind of define it by.
I guess on a similar note, my own wacky theory is that our dimension can be affected at any given time by up to 13 other dimensions, but which 13 can change amongst a potentially infinite number. I imagine certain dimensions would more likely be co-terminus (I term I believe I’m borrowing from a Dungeons and Dragons type source) with ours than others but who knows.
Oh, I hear ya. And although obviously inspired by RPGs, I do conceptualize my wacky theory more in the context of string theory and related ideas.
