  Discovered as an apparent pattern, a universal relation between geometry and
information called the holographic principle has yet to be explained. This
relation is unfolded in the present paper. As it is demonstrated there, the
origin of the holographic principle lies in the fact that a geometry of
physical space has only a finite number of points. Furthermore, it is shown
that the puzzlement of the holographic principle can be explained by a
magnification of grid cells used to discretize geometrical magnitudes such as
areas and volumes into sets of points. To wit, when grid cells of the Planck
scale are projected from the surface of the observable universe into its
interior, they become enlarged. For that reason, the space inside the
observable universe is described by the set of points whose cardinality is
equal to the number of points that constitute the universe's surface.
