There's a version he described in a video where all the matter and energy in the universe is eventually eaten by black holes, so (not sure why) there is no more spacetime. Just black holes. Then unimaginably slowly (if that means anything in the absence of spacetime), the BH's decay through Hawking radiation and this creates a new universe. I like the imagery which is, as you say, poetic.
Penrose also wrote a book proposing that the human brain is a quantum computer and its thought processes couldn't be simulated on a classical computer. I don't think that one has worked out.
