  In an extension of speculations that physical space-time is a fractal which
might itself be embedded in a high-dimensional continuum, it is hypothesized to
"compensate" for local variations of the fractal dimension by instead varying
the metric in such a way that the intrinsic (as seen from an embedded observer)
dimensionality remains an integer. Thereby, an extrinsic fractal continuum is
intrinsically perceived as a classical continuum. Conversely, it is suggested
that any variation of the metric from its Euclidean (or Minkowskian) form can
be "shifted" to nontrivial fractal topology. Thereby "holes" or "gaps" in
spacetime could give rise to (increased) curvature.
