  The standard interpretation of the observed redshifted spectra and
luminosities towards distant astrophysical objects is that the universe is
expanding, an inference which is found to be consistent with other cosmological
probes as well. Clearly, only the interpretation of {\it dimensionless}
quantities does not depend on the physical unit system as opposed to {\it
dimensional} quantities whose dynamics does depend on the arbitrarily chosen
system of units. All that redshift or luminosity measurements really indicate
is that cosmological scales expand {\it relative} to local scales. An
alternative choice of a ruler could be the distance between two remote
galaxies, in which case local distances have to decrease with time (with
respect to the ruler) for consistency with redshift measurements. In the latter
choice, microscopic scales such as the Compton wavelength, or the Planck
length, decrease with time, and consequently fundamental `constants' such as
the Planck constant, speed of light, Newton gravitational constant, and
particle masses, are spacetime-dependent. To illustrate this fundamental
indeterminacy we construct an alternative interpretation to the expanding model
that is characterized by a static metric with time-dependent fundamental
physical quantities. The two alternative descriptions, are referred to as the
`expanding' and `static' space perspectives, respectively. Cosmological
inflation, recombination, and all other early universe processes are unaltered;
the `expanding' and `static' perspectives are associated with exactly the same
cosmological model.
