The universe flying apart and cooling doesn't contradict Penrose, it's part of the theory just to address that point. An infinite structureless, massless universe is a singularity, or so the theory goes. Assuming this was "settled" (whatever that means in science let alone theoretical physics), mavericks like Penrose are frequently proven right. 'Kuhnian' paradigm shifts are the norm in science, particularly in a field like this. Expect many more...

Penrose's CCC predicts all biological life on our planet and all biological life on all other worlds within our universe will end, just like the conventional Heat Death. To point out this fact - that all biological life is doomed to die - was the purpose of my original post. We can talk about nuclear war, climate change, hostile aliens, and other short term threats to human survival. We will survive these short term threats or we won't. But in the long term it is 100% certain we don't survive. We only survive the Heat Death if it turns out we are living in a Matrix of sorts and the computers of the Matrix are hosted in a datacenter universe that is truly eternal, unlike our universe which will die the Heat Death. Or we survive the Heat Death if there is an eternal God who gives us a post-biological existence after the Death of our universe. My point is that present humans and far-future humans are in the same boat as prehistoric humans: we all must learn to face death bravely. Future humans will never have permanent biological immortality, because our universe does not allow it. Neither does Penrose's universe. Furthermore, Penrose's only testable prediction (CMB concentric rings caused by past reboot of universe) proved unable to be replicated by three independent attempts. Einstein's theory in contrast said the orbit of the planet Mercury should have an observable precession if true: so we pointed our telescopes at Mercury and lo, Mercury did indeed precess just as his set of equations said it would.

  Sure we will all die, assuming humanity was alive at the end. To be specific about my objection, you said that this event will not repeat and I'm saying, I'm not sure and neither are certain others. An eternal recurrence is not ruled out. Nothing would survive a reboot though, sure. To be clear, assuming there was an infinite reboot sequence I'm not saying that there would be life again, let alone intelligent life. I'm just making a statement on the fate of the universe.
