Entanglement Entropy and Cyclic Cosmology
---
We discuss how an infinitely cyclic universe
might be achieved by requiring that the entanglement
entropy of the introverse (visible universe)
be cyclic. This has the advantage that the
extroverse (the remainder of the universe)
becomes classically disconnected at turnaround
and may be jettisoned with impunity. This
avoids a multiverse and enables a model with
only one universe.

As an afterword, the status of the hypothesis
that the dark matter constituents are
primordial intermediate mass black holes
is provided.
