I know HN hates religion, but after being an atheist all my life, and graduating with a STEM degree (the 'S' part) from a top tier institution, I've started in the last year or so to turn to the church (Roman Catholic) and theism, both to find answers to some of life's mysteries, such as the origin of the Universe, and for personal reasons (I plan to start my initiation, starting with a baptism, within the next year…

Do you think satisfaction is a good measure of what we should believe to be true?

I am sure a lot of HN do it in private. In modern world (>90s) to be non-religious due to stereotyping people.

Nobel Prize winners are not immune to crank thinking, usually outside of their area of speciality. There is Linus Pauling and vitamin C, and Penrose also writing about consciousness having quantum mechanisms.

It’s a little unclear why his theory about the universe being reborn can’t be a possibility. It all just started 13.5 billion years ago? We simply don’t know.

Occam's Razor: what problem with simpler theories does this "possibility" solve?

IANAP - why are these ideas so controversial? The article seems to suggest he has some (potentially) supporting evidence, and I don't have an intuition for how damning the counter-argument is ("This would necessitate making all particles lose mass as the universe gets old." Again, IANAP and physics can get weird).

I don't understand what you expect me to take from this by your sharing of it.

I myself am partial to the Latter-day Saint teaching that matter/energy has always existed (and forever will exist) and that the creation of the world involved "organizing" existing matter in an iterative process. That matches the pattern of creation I've experienced myself where I take something that already exists and iterate on it until it is in a refined state that I desire.

I find it hard to believe that the mindboggling complexity of protein machinery was purely accidental/probabilistic. I understand how evolution works, and it makes sense, but... to me at least, it seems more likely that there was a creative iterative process that "guided" matter towards the evolutionary system we have on earth vs lightning striking an ocean full of amino acids and DNA/cells/proteins coincidentally arranging in the right configuration to jump start evolution.

Those are controversial because in science you show the proof of something occruring, an primary proof being shown here mostly anounts to „trust me bro, the guy saying this got a nobel award in physics”. But the fault here is on media reporting, not Penrose himself.

> What proof does the physicist have for this theory he dubbed “conformal cyclic cosmology” (CCC) that goes against the current Big Bang dogma?

It doesn't go against the current "dogma", as the Big Bang theory only covers history up until a fraction of a second after the big bang. Anything before that is basically fair game, even though some ideas are further out there than others.

Penrose admits it's a "crazy idea of his", and that's fine. He's looking for evidence and not just speculating. It's much less out there than Hossenfelder's thoughts about FTL travel in her video from yesterday. And not even remotely comparable to Linus Paulings musings about vitamins.

Do you think satisfaction is a good measure of what we should believe to be true?

Don't you think that question presupposes a materialist world view?
