Thus, even though the more general laws of relativity and quantum mechanics contradict the laws of classical physics in certain cases, they nevertheless agree in a certain limited domain. In understanding the relationship between laws of differing degrees of generality, mathematical concepts are often useful. One such concept is the idea of dimensionality. The full Reality is like an infinite dimensional space. Subtle levels correspond to viewing Reality as it is projected into high dimensional spaces.
Gross levels correspond to viewing Reality as it is projected into low dimensional spaces.
There is a lot more distortion in the lower dimensional projection since more information is lost. Moreover, the full Reality can never be captured or described within a finite dimensional space. The act of projection is an ignorance of certain dimensions of Reality, and the result of the projection is a limited aspect of Reality. If one is unconscious that any projection is happening, then there is no knowledge of ignorance of the other dimensions and the projected reality is mistaken for the whole thing. If one becomes conscious of the act of projection, however, then the illusion is gone and one will never be fooled into thinking that a finite dimensional projection is anything more than a limited slice of the infinite dimensional Reality.
