So I was having a discussion with the boys tonight about dimensional things--like what does a fifth dimension mean or whatever. I had an intellectual breakthrough for myself tonight. So, as mathematical/physics theory has it right now, something will exist in all the dimensions. However, it occurred to me that a being that was able to perceive a higher dimension should then be able to perceive things much easier in lower dimensions than vice versa. For example, if a higher being were able to navigate time, it could much more easily observe another being that did not have that power. The lower being could only perceive the higher being when their time axis intersected. If the higher being could also see through time, then it could perceive the lesser being without being noticed.
Basically all I'm saying is that humans right now have senses that were made for survival in the third dimension and although we are aware of time and can observe it's passing, there's nothing we can do about it. But if we could navigate it, it would vastly change our perceptions.
I'm gonna stew on this a bit and see if I can explain it better in the future.
