Whatever else may or may not be true about magnetic monopoles,
their existence does not depend on gravity. If they can exist,
they can exist outside black holes. If they can't exist, then
they can't exist.
Contrary to what RP moans on about, the existence of monopoles
is still an open subject. All you have to do is insist on the
Dirac quantization condition, and they are perfectly well
allowed. They wind up looking like a very long solenoid,
where the flux inside the solenoid is of a specific value
such that it cannot be detected by an electron that moves
once around it in a circle. Enter such lovely things as the
monopole bundle, the AB effect (I'm lazy and can't spell
Aharonov with any reliability), symmetry breaking, the
"hairy ball" theorm, and so on.

It's not clear that superstrings have *any* model of what
the universe would behave like. Or rather, they have far
too many models, and no predictive ability.
