For a particle to fall into a hole, it has to meet its antiparticle. It's
well known that when both are closeby the configuration is NOT very
stable. :)

Into breaking the brane up despite binding energy, perhaps.

These are very preliminary speculations. An actual physicist with the
requisite maths and more than an undergrad degree can try seeing if they
can develop this into a truly predictive, quantitative model. I'm just
indicating that there might be something to this.

Meanwhile someone should investigate whether a superposition of all
evolutions from all possible initial states of a given universal Turing
machine has interesting statistical mechanics...

Topological defects such as knots and such, zones where the effective
physical constants are out to lunch, even junctions like in semiconductor
chips?

Anyway, I disclaim here that most of that stuff will, like many
speculations, probably turn out to be false. But checking it out may lead
in interesting directions. And someone really should check out the
nonlocal correlations that occur in quasiperiodic tilings and whether they
might give a clue to what goes on in quantum physics with its nonlocal
correlations -- it shouldn't be hard to track down that Martin Gardner
book I mentioned on the internet.
