@JohnRennie Thanks for the link. That's related, but my question is in some sense opposite: there the question is about wrapping space up more tightly around a line, and mine is about unwrapping it (orbifold singularities vs. monodromy in math)

The idea of the setup is to create a loop that cannot be contracted without at some point becoming "prohibited" in some sense.

@JimGraber Thanks! So if you pack the black holes maximally close then presumably trying to send a mass between two of them will collapse the whole thing -- will the same thing happen if you shine a light?

I see. Thanks Jim! So then say the radius of the ring is very large and the holes are placed within epsilon of being as close as possible to each other without collapsing (so I'm approximating an infinite line of black holes).
