Thank you for your comments, @carton383.
Folks who ponder #TimeTravel are rather compelled to think about splitting or parallel universes. But there are other lines of reasoning for scenarios like Schrödinger's cat or #superposition having to do with limitations in our sensory and cognitive apparatus. The apparent collapse of multiple narratives (timelines) into only one may be a function of how our brain works, and the #Newtonian low-dimensional geometric space that we evolved in. We are simply not engineered to see the other narratives, or rather the bigger picture, which may all be one hyper-complex narrative. It is our reading. Didn't #Schrodinger say that the cat is both dead and alive? Parallelism may be more locally integrated in ways that we can't process, instead of a version A here, and a version B elsewhere. Versions A, B, and others may be all here, but not accessible to us. Just some thoughts.
We'll be posting about #quantum #decoherence in a few days.
