Easier to grasp for the current (and previous) cycles perhaps, but where did the first universe come from?Makes sense.
The idea that the universe began as a point of singularity from nothing is hard to grasp. But the idea that it cycles from expansion to contraction over billions of years seems to be easier to grasp.

Interesting - a lot of physicists think it’ll be infinite expansion followed by heat death. I guess we’ll start collapsing again or is something more exotic thought to happen?

Not sure how much more exotic it could all get
Everything we know up to this point says heat death of some kind. It’d take some drastic evidence to shake that view at this point, even if it is Penrose making the claim.

Their paper discusses some wild stuff, but even that's proasic compared to what you raised, which is the big question: How does existence...exist? [Or, to borrow phrasing from Hawking: Why is there something rather than nothing?] I love this question because it puts us face to face with the seeming impossibility of existence: Either nothing existed—no reality whatsoever—and then reality spontaneously came into being from absolutely nothing (not to be confused with, say, the spontaneous generation of particles from quantum fluctuations in spacetime, since spacetime, and all its associated laws, is something), or reality has existed forever, with no possible explanation for its existence.Easier to grasp for the current (and previous) cycles perhaps, but where did the first universe come from?
It's not only that we don't know why, but that it seems we can't ever know why.So there was once no there there, or else there was always a there there. Either way we don't know why.
I like that. It leaves room for so much more sci fi, and so many more creation stories as well, not to mention ongoing job opportunities for everyone from poets to scientists.... until "the end of time."
