more cautious approach [*reverse*]{} this conclusion? The question is legitimate, since a heuristic argument, whose qualitative consequences are confirmed by a more cautious analysis [@DMP], suggests that near singularities the [*effective Planck length might diverge*]{} as $\lambda_P  g_{00} ^{-1/2}$.

This might well introduce a metric dependent factor in our formula for the electromagnetic radiation caused by the magnetic moment of neutral matter, making it considerably larger in the last instants before the collapse into a black hole, heuristically as $$\frac{d \cE}{dt}      =   \frac{1}{g_{00}^{2}} e^2 \lambda_P^4 M^2 R^2 \omega^6,$$ where $g_{00}$ is the time-time component of the background metric.

This qualitative conclusion is supported by the results in [@DMP], which mean in particular that in a flat Friedmann- Robertson-Walker (FRW) background (which is spherically symmetric with respect to every point), with metric, in spatial spherical coordinates, $ds^2 = - dt^2 + a(t)^2[dr^2 + r^2dS^2]$, the size of a localisation region centered around an event at cosmological time $t$, measured by the radial coordinate $r$, must be at least of order $\lambda_P a(0) /a(t)$, $t = 0$ being the time of the present epoch.

The situation that we have in mind, namely that of a neutral object rotating in the gravitational field
