A related question looks something like this: Can two particles, two points of space, be related; be in sympathy; be "entangled" -- regardless of the distance between them? Well, Quantum Entanglement, AKA "Spooky Action At A Distance" -- says yes. If so, if that's indeed possible -- then the next question looks like this: Are these two particles, two different points in space, really somehow the same particle, the same point in space, but it's just that this particle exists in two simultaneous places in our dimension, but in only one "place" (for lack of a better term!) -- in a dimension of the Universe higher than ours? If the answer there is "yes" (I don't know that it is; I don't know that it isn't) -- then some other really interesting questions come out of this, such as: Is it possible to link two particles (two very small geometric areas of space) -- not just in a higher dimension, in space, but in TIME -- as well? And then of course, if the answer is "yes" again, then the next question is how to do this with groups/multiples of points in space, and multiple points in time, etc., etc. But the thing that starts all of this line of questioning off is the original one about two particles in space, and can they be linked, such that they be in sympathy, such that changes to one affect the other, and vice-versa... Anyway, there are some very interesting questions related to the dimensionality of space, and how this dimensionality, if it exists, could or would apply to Physics... If it indeed does exist... I vote that we call this future science: "Dimensional Engineering" Sort of like what Star Trek's "Scotty" character would do, if he were a real person... Reminds me of his famous quote: "Ye cannot change the laws of Physics!" -Star Trek's Montgomery Scott ("Scotty") PDS: Well, not without going up a dimension or two! <g> (But all of that is highly speculative at this point in time; as of this writing!)
