Okay, let me start this off by saying this, I have no idea what section this belongs in. On break between Spring and Summer classes, I stumbled upon a tesseract, or hypercube for the first time. And it got me thinking, on a purely philosophical level (ie, I have no where near the mathematical or physics knowledge to try to approach it scientifically). What a body moving through 4 dimensional space would experience. I've had several ideas come and go, but, based on the appearance of a tesseract, at least it's representation when drawn on a 2 dimensional surface, the best assumption I've been able to make, is that, in 4 dimensional space, you would observe movement in 3 dimensions exactly as we do now, however, my visualization for 4th dimensional movement involves the object or body expanding volumetricly (I don't think that is a word) as it moves "outward" in the 4th dimension, with the opposite happening as it moves "inward" in the 4th dimension... Now, let me apologize now if this is the most nonsensical thing you have ever read. Trust me, I have put off bring this question to all of you for fear of this. However, as many of you probably know, when your brain gets stuck on something, there is very little you can do. In any case, I appreciate any insight into my question, because as of now I can't go 5 minutes without pondering on it. Requ.
