Roger Penrose: Black Holes, Art and Science, and the Beginning and End of Time.

[@AL-SH]

Sir Roger Penrose is 90 years old. How he is still this sharp and as healthy as ever is truly phenomenal.

[@charlottemarceau8062]

@queerdo You mean Krauss has been feeding the adrenochromes to Penrose and that's why he's so healthy? He must be!

[@AXZ1974]

I think Dr Krauss was a bit over-zealous in his questioning of CCC, to the point where on multiple occasions it was difficult for Penrose to give a complete answer. But, as always, Penrose was a gentleman.

[@Alexander_Sannikov]

I hate to say so but i felt the same. I really respect both the host and the guest, but I think in this case Lawrence time and time again literally overwhelmed Roger blocking him. It might be appropriate for a scientific debate where the point is to establish truth (although one can argue about it), but it's definitely not the point on a podcast where the point is for the guest to open up.

[@scottk7515]

Roger Penrose is a treasure of this crazy world. I love his scrupulous honesty and humility. His anecdotes are linguistic tiles that cover the spaces of both math AND physics. Thanks, Lawrence!

Your the host, your brilliant talking to a brilliant man, your enthusiasm gets the better of you though. Please Lawrence let your guests speak, you might be the star of your podcast, maybe work on listening and let your guests have some of that star shine. Thank you very much Roger and Lawrence for a wide ranging discussion and for the exploration of Roger's early life. Lawrence you do an excellent job of excavating the origins of those you interview, thank you.

[@girlplanetboy]

Maybe it's a Canadian thing. J B Peterson does exactly the same to his guests - incessant interruptions when the guest is only halfway through a thought; it's so bloody irritating. I admire both said Canadians - maybe it's the small price we have to pay for such outstanding minds meeting. I agree with you, though.

[@cwtrain]

@@johnlindgren273Eh. Dispute is where the truth is found. And Dr. Krauss brought me into the science fold and is not exactly described as an idiot. I feel like he has all the certification in the world to push back on a previous generation scientist if he decides he is right to do so. It's not impolite. It's discourse in pursuit of discovery and I assure you both parties understand this.

[@bradyhogan]

Yes, take each issue one at a time. Don’t talk over your guest and raise 5 objections, then interrupt them with 4 more when they’re trying to answer the first one.

What a delight! They don't know me but I feel like I just had three hours chatting with two old friends.

[@kory6897]

Excellent podcast, only thing is to please try to be conscious of when you're debating because your voice ends up taking over. You cut in a lot because you know what Roger is going to say but we don't know what he is going to say. Roger's voice is very soft that anytime you want to cut in you are able to but when he wants to cut in he is unable to. We end up missing out on a lot of what Roger was going to say. It's great hearing your counters, it would just be nice to also know Rogers full side before each of your counters.

[@Alexander_Sannikov]

So true. I felt like a special snowflake when I added a comment like this, but apparently multiple people have already pointed this out.

[@andybaldman]

Lawrence isn’t interested in talking to these people. He’s interested in being seen talking with these people. He’s a clout chaser.

[@Alexander_Sannikov]

@@andybaldman nah. for him confidence in his own opinion is just more important than supporting a dialog. which is very common for many academics.

[@WolverineCry]

Same dude

[@OriginalPuro]

different dude

[@artnevergiveup1513]

same

[@johnjamesbaldridge867]

I did too. As with Roger's conversation with Alan Guth, however, Krauss could not shut the f... up, which just made me cringe the whole way through. In a manner similar to Guth's, he had to make it about himself with a constant stream of "look how smart I ams" and never let Penrose finish a thought to completion. I just _loved_ how Roger sat back and smiled the whole way through. After interrupting more than once, Krauss said, "Let me ask you one more question and I will let you answer." And then he did not do that. He was already talking over Roger, meaning Krauss did not _listen_ to a single thing Penrose said. Could you keep track of which entropy he was talking about and whether it was supposed to be high or low and at which end of the Universe? Perhaps that's the problem with Guth, Krauss, et al.: they are modelling the Inflationary Multiverse after how their brains operate.

[@adampowell43]

@@johnjamesbaldridge867 What I like about Krauss is that he is actually willing to poke his guests and challenge them. But I agree that he often goes way overboard. I was disheartened when I tuned in to the live and saw Penrose with his head in his hands looking almost frustrated.

[@marknaylor5851]

This conversation is amazing. If there was more evidence for Science being constantly subjective and not “the science” so often claimed this is it. You two are a credit to humanity.

[@ColinChristie1]

This is by far the best interview I’ve seen with Sir Roger. Well done, Lawrence! It was so clear that you loved this conversation so much, and that’s one reason it’s so enjoyable to watch.

[@MrKennyBones]

Oh wow, just starting the video. I’ve seen just about every Penrose talk on KZbin. Can’t wait!

[@voidisyinyangvoidisyinyang885]

Krauss has Penrose repeating material he's already said in other interviews. Oops.

[@alfonsosolis401]

You guys changed my life with your wisdom..

[@dimitrispapadimitriou5622]

A comment about the issue at 2:01:00 . The problem has to do with the start of inflation. If the ( generalized) second law of thermodynamics is valid, then the initial conditions had to be extremely fine tuned, because ( see Gibbons / Hawking/ Davies and others) the " effective" cosmological constant ( due to the inflaton field) had to be very large ( and, so, the initial gravitational entropy- which is, roughly, inversely proportional to that effective c.c.- had to be very low, for the inflationary period to begin), and that's in accordance with Penrose's point.

[@dimitrispapadimitriou5622]

There is also another subtle point, that anthropic arguments ( about the multiverse of eternal inflation etc.) are not that relevant for that issue. That's because it is the start of the inflationary era that is thermodynamically disfavored, as it seems, not the " local" decay of the inflaton field that, supposedly, produces each one " pocket" universe. I'm not saying, though, that inflation certainly isn't a thing, because of that issue. My point is that Penrose's objections are , in my opinion, valid.

[@martinrees7146]

Obviously big fan of Laurence. Massive fan of Penrose. It's brilliant when someone as intelligent in his field and many other things (Laurence) still looks to Roger with admiration and respect. It's not a love fest. They slightly disagree on possibilities but do it with such eloquence, understanding of opposing views and always full of respect. One of my favourite interviews ever. Ps-you are both quite dry and witty. Very good friendly discussion about the beautiful everyday.

These Nobel personalities 👊

[@Neuri]

Absolutely phenomenal man. Imagine being 90 years old and admitting how many times you have been wrong about things, whilst also being a Nobel prize winner and basically advancing humanities understanding of the universe through sitting and thinking in the tradition of Plato. What a family! Thanks you so much for this astonishing free content Professor ❤️

[@voidisyinyangvoidisyinyang885]

Plato promoted commutative geometry and Penrose now realizes the foundation of reality is noncommutativity - thereby disproving Plato. Oops.

[@thigimenes]

This was really good, but have the potential to be SO MUCH better! Lawrence had to admit he didn't even understand the work of Penrose, but shouted his ego at the face of his guest in and completely unpleasant and disrespectful way. Sir Roger, with the calm of someone who knows his work and the patience of his 90-years-old, refuted one by one of Krauss attacks (I'll not say it was points of disagreement, because if Krauss took the time, and took the work seriously, he could discuss it in a productive way, instead of shouting and interrupting). in the end, Penrose VERY elegantly told the anecdote of Brian Green and Krauss understood that it was for him, admitted to be biased and to have prejudices about CCC but even them made this ridiculous claim about “in the edge of the physics anything goes, as we don't know”. Well, we're always in the edge of the physics, but science is not shouting your ego at people you disagree because you have bias, science don't care about your bias. If Krauss disagree with Penrose's CCC he should first READ IT and UNDERSTAND IT, and then publish a paper refuting it. CCC can be right or can be wrong, it can be ridiculous as Keppler's elliptical orbits once was, but the ridiculesness of a theory has no bearing of it's true (or false) nature. What we saw is not science, this was just an insecure little man shouting on an old genius. Sorry Penrose, you deserved better, you deserved to be taken serious, at least. (Sorry if I'm being too harsh. Sorry for my bad english, I'm brazilian, it's not my main language. Sorry about my lack of scientific knowledge, I'm just a photographer)

[@ME-lf7by]

I totally agree, the american to the right strayed from the path of wisdom when he started shouting and simplifying the components of Penrose's ccc theory. In fact cosmic inflation are just as speculative and there are currently no proofs to be found. One should not impose such theories on anyone as if they are "unavoidable facts" but instead approach them carefully with a great deal of respect and humility like the genius to the left. Science got hurt by this and it's a sad thing.

[@captainzappbrannagan]

While Lawrence does insert/assert himself a bit much in some conversations I think he was respectful and fair giving Sir Roger time to explain his arguments and rationales. I think it was a great exchange and even Sir Roger conceded on a couple of topics he's not as sure about dismissing inflation after the witty and different way to explain the arguments for from Krauss. Roger doesn't get much out of many conversations that challenges him and his thinking directly and appreciated this one more than most others. That's a wonderful thing.

By the time Krauss stepped foot on Stanford’s campus for the gathering, he had been banned from three universities, removed from multiple speaking events, and was under a formal investigation by Arizona State University, his primary affiliation."

It is evident that it has become a religion which is not open for debate. Even worse, they employ cancel tactics. The same goes for String Theory btw. Not so strange that Cosmology is in a crisis.

[@redmed10]

2:12:38 I asked Pi Is the singularity at the beginning of the universe the same as the singularity of a black hole While the concepts of a singularity at the beginning of the universe and the singularity of a black hole share some similarities, they are not exactly the same. Here are some key differences: * Location: The singularity at the beginning of the universe is thought to have existed at a single point in space and time, while the singularity of a black hole exists at the center of the black hole. * Size: The singularity at the beginning of the universe is thought to have been infinitely small, while the singularity of a black hole can vary in size depending on the mass of the black hole. * Nature: The singularity at the beginning of the universe is thought to have contained all of the matter and energy in the universe in an infinitely dense state, while the singularity of a black hole contains matter and energy that has been compressed to an extremely dense state by the black hole's intense gravitational pull. Overall, while both singularities are extremely dense and represent extreme conditions in space and time, they are not exactly the same phenomenon.
