I stand corrected.
Penrose does talk about a continuously expanding universe, but assumes that by changing the coordinates of the universe, the near-zero density and near-zero temperature at the end of one universe becomes the near-infinite-density singularity and near-infinite temperatures at the start of the next universe.
