I’ve been wondering about this most incredible idea, that, quantum mechanically speaking, there may exist any number of universes. As hard as I try to visualize such an idea in my limited three-dimensional capacity to imagine spatially it all seems pretty much beyond comprehension. When I add time to the mix I can sort of get an idea of it all. After all, the world as it is right now is not quite the same as the world as it is right now. A micro-second in the past or the future might define an entirely separate reality, a parallel existence.
I wonder if these separate realities float around, bump into each other and maybe intersect for brief periods. Is it possible the remarkable sparkling landscape you saw last week was of another world never to be seen in your reality again? Maybe realities are nested within each other. Do the places you glimpse through the trees and bushes on that familiar winding trail through the woods have a certain other-worldly feel?
I find such thoughts intriguing. I revel in the possibilities, and, as long as I don’t think too hard about trying to define the multiverse in three-dimensional terms, I remain content in the limitations of my understanding.
