Heisenberg\'s Uncertainty Principle
I didn't mean to imply Heinsenberg was the first to theorize "multi-dimensionality", merely that his principle "seems" to lend credence to this long hypothesized possibility. I'll try to explain how, but remember, I'm a lay person.
When an electron jumps orbit, it emits energy (quanta) in the form of a photon. (An as yet, theoretical wave/particle.) We can induce this event as well as several others that allow us to attempt to measure such events to try to determine just what the behaviour of these "quanta" is. There are many forms of quanta we can perform this experiment with in the particle accelerators. (I wont go into Leptons, Hadrons, Photons, Mesons, or other descriptions of Quarks here. Suffice it to say that the following problem exists for virtually all of them.)
In trying to measure this event, we place a medium or "screen" in it's path to detect its presence. An impact point occurs in the medium showing where the "particle" struck, but the path it took indicates that it behaved like a "wave" during transition. (This ALSO becomes a topic for separate discussion as to what THIS means.)
At this level of matter/energy, the means we use to conduct the measurement itself, actually influences the outcome. It is also imprecise enough that it becomes impossible to determine the velocity of a quanta at the time we know its exact position. It is equally impossible to determine its exact position at the time we are able to measure its velocity. This is the core of the Uncertainty Principle, but it gets worse.
Since we "know" we fired a "particle", and an impact point shows that a "particle" struck the medium, and it behaved like a "wave" on the way there, we have another seeming paradox that arises. In certain experiments, the "impact" seems to occur at the SAME INSTANT as the "firing". This is what Einstein referred to as the "Spooky force at a distance" where a particle comes into existence in two places simultaneously!
It is THIS situation that then led to hypothesizing about the possibility of evidence for multi-dimensionality. (Remember, Einstein never bought into it tho since this is in fact at odds with relativity. If the quanta is a particle, how can it travel at, or faster than light? You don't even have to bring in the "mass increase" problem to complicate it even further, since the speed problem alone is at odds with relativity.)
In SOME cases, the "target" particle even seems to "spring" into existence at the target an infinitessimaly small instant BEFORE it is fired. This is what leads to hypothesizing about "time travel". In the truly empirical or physical sense, that is.
So... The Heisenberg principle itself does not hypothesize multi-dimensions or time travel, but the problems it poses do.
I therefore have come to believe that we should never rush to conclusions regarding dimensions or time travel based on theories that arise out of our inability to measure with certainty in the first place. It's THAT simple for me.
Multi-dimensions and time travel are going to have to come up with WAY WAY more foundational evidence than we now have for me to buy into any of it. In fact, I think we are using these theories to fool ourselves into believing something we have always WANTED to believe, but have never had any shread of empirical evidence for. (See my Bill Nye analogy for this.)
As for metaphysical or etheral time travel, sure. Why not. You can go anywhere your mind will take you if you want to. But this is a seperate issue.
Finally,
You'll have to explain to me what you mean by "multi-density". I'm not familiar with the term or how it is relevant in the context of time and dimensions. I think this must be a seperate issue also.
Thanx.
