> "The" fifth dimension is a scifi concept, > not a real one. I'm confused now. How Is it possible for a dimension to "not be real" when a dimension is just a way to relate multiple points together? Unless you run out of points, can't you describe their relation using as many dimensions as you need? Maybe our communication is breaking down over the term "parallel universe". I don't mean it as a sci-fi thing, I mean it as a Schrödinger's cat thing. Without possible universes, we can't explain our intuition that an event can have multiple outcomes. Why should one of them happen, and not the others? With possible universes, there's no problem, because they all happen. How would one describe the relation of where they happen without a dimension higher than time? I don't mean a parallel universe as some fantastical place that we could "visit" etc.
