Hidden dimensions (2)

From my previous post it is evident that the existence of hidden dimensions is a strong possibility in our Universe. The existence may be determined by the strength of gravitation field or space-time curvature. But here one issue arises.

The act of imposing a boundary in the system (i.e. its model) itself raises the possibility of introducing an artificial dimension, which may be very weak or very strong, in the dimensional break up of the system. The dimension is artificial in the sense that it does not exist naturally in the form that it is introduced into the system by the imposition of a bound on the system or phenomenon. More
interestingly, the nature of this artificial dimension will depend on the nature of the bound. That is, whether the dimension will be extremely weak or strong or medium will depend on the nature of the bound.

Thus in reference to the previous post, this raises the possibility of a paradox esp. in the case of hidden dimension of the Universe- i.e. whether the hidden dimension, if detected, are natural or artificial. Every model of the universe has the potential to induce a extra dimension that is not naturally existing in the Universe.

But if we insist that some model is able to capture the “reality” of the universe, then we have to account for whether the extra dimensions detected is due to the model or is existing naturally. this seems to be a challenging problem.
