I was thinking about extra spatial dimensions. So we have three visible dimensions, but most of physics now is predicting that there must be more. Brian Greene describes this as tiny curled up dimensions. The dimensions are so small that we can’t see them. What I was thinking about is why we must call them too small to see. Isn’t it perfectly logical that the dimensions are just as large (maybe larger) as all the other ones, but since we are three-dimensional beings we just can’t see them like in Flatland. Why must they be too small? Is this just some analogy in attempt to satisfy the media?
Edited: I re-read this post and was horrified. I had spelled “spatial” as “spacial,” so I quickly changed all the spellings. Then I looked it up in a dictionary, and apparently either one is correct. Interesting.
