The discussion about how many dimensions "really" exist is pointless because there is no other way to define "real" than to define it as the reality that I experience. And I experience 3 dimensions. Physics is a collection of models expressed as formulas, plus recipes of how to translate these formulas to the reality that we experience. If I have a formula with 5 dimensions in it that tells me how to build a teleporter then that's great but it doesn't change the fact that the world that I experience is 3 dimensional in space.
