Principle X – Empiric – Imaginary Multidimensional Worlds existence:

In Euclid’s geometry, if we consider ourselves a point in a plan, we only can observe just a line: this means that if we are a point in a two dimensions world, we only can percept one dimension.

The same rule can be extrapolated to understand that if we are an Entity in a four dimensions World Scale (X, Y, Z, and Time) there is, at least, another extra dimension that we cannot see or understand its existence because it is not possible to percept it from the World Scale where we are in. Only using the imaginary complex number i=(-1) ½ it is possible to mathematically define that imaginary dimension from the World Scale where we do belong.
