These are suitably thought-provoking answers - thanks for taking time to post! I'll do some searching for reading about expansion vs. inflation now.
Have a good week everyone

Apologies in advance if this is a stupid question.
I'm told the Hubble Deep Field shows galaxies as distant as 13 billion light years away.
13 billion years isn't far off the apparent age of the universe - 13.75 billion years, says Wikipedia, from estimates based on the Hubble constant...
I think it was that Horizon: I was watching too.
So is the idea that... because of matter-energy equivalence and the conservation of matter-energy, Penrose's end-state of the universe is effectively all energy (matter-energy decayed to radiation) together in a dimensionless point?
