Query: Big-Bang Nucleosynthesis as a Probe of the Geometry of Superspace   We study the effect from a general ultralocal supermetric on primordial
nucleosynthesis for Friedmann-Robertson-Walker Cosmology. The parameter
$\lambda$ of the supermetric changes the effective number of degrees of
freedom, $g_*$, which modifies the Friedmann equation. This modification
produces variations in the production of primordial $^4He$. The observations of
the primordial abundances of light elements ($^4He$, $D$, $^3He$ and $^7Li$)
allow to estimate bounds on the values of $\lambda$ consistent with these
observations. We obtain $0.87 \le \lambda \le 1.04$. In addition we analyze the
importance of $\lambda < 1$ to explain possible incompatibilities in the
standard Big-Bang nucleosynthesis.
