Class 5 - kinda off topic but inspired by this week's questions

When I was an undergraduate, I took a multidimensional math class. It was called something like 'Beyond the Third Dimension'. I took it because the instructor was brilliant and it pretty much blew my mind. I do have a knack for numbers, but my training and experience was not at the level of being able to comprehend 4th and 5th dimensional space, and I had no real intention of even trying. (There were two TAs for the class - one was involved in computer modeling of hyperspace, and the other was a poet. Fortunately, I was in section with the latter.) I just wanted exposure to some of those mind-blowing ideas, to have a little more idea of some of the things of which I was totally ignorant. In that I succeeded! My takeaway for the class was to get a very broad-concept grasp of things. 

In all of the talk in this class that we've had about dark matter and dark energy, part of what has been running through my head is what if some of the ‘missing’ matter/energy resides primarily in dimensions that most of us don't know how to perceive or access. Those brief moments when electrons appear in one place and then another place - who's to say those two places are not contiguous in some other dimensional space, that we are simply seeing projections of a more-than-3D object pass through 3-dimensional space? I don’t know enough to provide any substantiation or evidence for this idea – I just know enough to wonder…  (Alas, this wondering does not fall neatly into any of the questions for the week, but I started intending to write about fractals and sacred geometry in hyperspace, and this is where ended up.)

(By the way - if you have never read Flatland by Edwin Abbott Abbott, I highly recommend it. )
