The question originates from what is often said in accounts of superstring theory, that (perhaps) 7 space dimensions might be curled up into such a tiny scale as to become undetectable.
So the question came up, if dimensions might be curled up or extended into different scales, say "very tight" or "very open", might that mean that also our 3 familiar space dimensions could be extended into different scales? and if so, what might that mean in practice, if anything?
We assume that the 3 space dimensions of our spacetime are "equally extended", the 3 of them to the same scale. 1 light year has the same extension in any direction or at least it looks so to us. Is it conceivable in any way that the 3 spatial dimensions might be extended to different extents in our whole universe? and if so, what might that mean? could there be any observational clues in one or another sense?
Thanks!
