      the penrose tiles thing is what brought him to my notice, it's one thing to be smart, but to be smart outside your field, and to solve 100 year old problems for fun boggles me. i was beginning to think his marbles had begun escaping when he brought up the subject of micro-tubules, but it seems there might even be something to that. my hero too.

    What an extraordinary privilege it is to be able to hear a conversation between a Nobel laureate who not only continues to explore the frontiers of knowledge but does so in unconventional, not to say eccentric, ways, and an accomplished, seasoned theoretical physicist who is also one of the great science communicators of our time. It's fascinating to glimpse and even to feel the tensions in the physics community, and at the same time to appreciate how much confirmed and shared knowledge we have gained. I'm enlightened; I'm uplifted; and I'm grateful. Thank you both.

And neither throws their toys out of the pram about the others' perspective.

      Greene was fine up until nearly the end, where he (successfully) drew out Penrose to mildly voice his departure from (modernized) string...uh, 'theory (theories)'... and then countered with a rebuttal of the objection by, ironically enough, presenting a scattershot of leading edge string -theory- conjecture variants, with a so-that's-a-wrap, thank-you very much, The End (roll classy music outro).
      Penrose was clear that he found the original concept of strings intriguing, and Greene could have ended by asking, "OK, elaborate on the features of string theory that you took a fancy to?...what could have been a better path to explore?"

      Man if everyone could just grasp this simple act of having a conversation with someone who has an opposing view, I can only imagine how great a world we could live in together... unfortunately politics and yes religion (sometimes the worst offender to this idea) basically keep the majority of the population from ever learning, much less practicing these type of dialogues/conversations...so many are still of the ingrained mindset that, if your not on my team, then you "must" be against me...Why as human being is so damn hard to realize the obvious, that being, we all have FAR MORE IN COMMON, than we do in differences...It starts with how we are indoctrinated from the beginning, and while breaking away from that indoctrination can and does happen, for many it's so ingrained to believe that should they question what they've been told, then the whole thing will just crumble to the ground...And this couldn't be wrong.

      @@Jackson09 I couldn’t have said it better myself. I don’t get to say this often, but I agree 100%. Religion is where it all begins, they start brainwashing their young parishioners into their cults. They pretty much inoculate them from asking questions. They teach them to be obedient and to be afraid of Gods wrath. Until they are afraid to even think about the inconsistencies that are found all through their religion. And the truth becomes a very scary thing that must be avoided. Because anyone that looks to closely might just be tempted by Satan and could cause unholy thoughts to arise. And fear is a powerful tool. And religion’s have been using it as the foundation for controlling their sheep for thousands of years.
      I bet you felt pretty alone when you were growing up. Anyone who chooses to look more deeply eventually will be either cast out or pretending to believe something they know isn’t true. It’s hard to go against the beliefs of family and friends. But it’s harder to just ignore the truth and pretend everything is okay. It’s truly a evil thing to do that to adults, but they do it to children.

    Dr. Penrose. I hope you happen to read this at some point. I would just like to say these few things.. Your views and feelings on these big existential questions, have always resonated with my own so perfectly. I, like yourself also don't feel comfortable with the exponential expansion as an explanation. The expansion unending, heat death, maximum entropy no detail, the end forever etc... I LOVE your theory of Aeons, and how you say it wasn't initially respected. I fully believe the same and I have had such a similar experience. The big bang being a continuation of a remote future of the previous cosmic Aeon. It is great to say that big bangs have low entropy in gravitational order, expansion has to be overcome, the big bangs are special, photons might get through, the conformal geometry flows through to the next aeon etc.. But we cant just step out of the disorder at the end into a new perfectly ordered big bang. We'd have used up all the order long ago. We have only seen that entropy marches on,. What new big bang, new Aeon, conformal continuation will our photons enter if entropy has won in this layer of conformal geometric progression. What conformally invariant hero will remain to go through and save our backs if expansion is not stopped, and no information remains, only complete entropy. We have to win, we have to find a way to beat entropy, someone has to restore order. I have been working on this for some time.. Entropy is loss of order, potential energy is distributed to more random arrangement. And as Brian Green says, we humans are like little widgets running around and causing increases of entropy. Consuming energy. Making the universe expand just that tiny bit faster with every thing we do....

      @bp1910 หลายเดือนก่อน

      It's very likely I am misunderstanding a great many things. Be that as it may, it seems to me that Sir Roger Penrose has provided an elegant solution to the critical entropy. In the far remote future of the previous Aeon, if the remaining ultra massive black holes have tidied up the entropy, they may evolve to an even lower temperature. Upon reaching critical absolute zero they then radiate the only forms of energy (massless photons and gravitons) which are capable of the translational invariance required for the conformal geometrical inflation.

    • @THEmomentumJUNK1E
      @THEmomentumJUNK1E หลายเดือนก่อน

      @@bp1910 Wow. Very explanation there. My above comment was only the first part, leading up to my theory of how to achieve conformal translation invariance. My view is something like this: Critical entropy will not naturally evolve into a translationally invariant medium. Even with the help of ultra massive black holes. The models and cosmic observations we have seem to indicate now way for the entropy in black holes at the end of the universe to conform under causality. With accelerating cosmic expansion whatever they might radiate is just lost, with dark matter filling the voids between with ever growing randomness and proliferation and domination. I feel that we need a new force to come into the fray, a force to challenge the flow of entropy, the invasion of dark matter, the acceleration of expansion. Perhaps one that increases in strength and influence as order decreases. I have started looking for this force by studying what is the results of, or the opposition to entropy and entropy's effects. I have found a candidate for an observable effect of this new force: Complexity. When a system such as a Human Being causes an increase in entropy, for example by moving, hunting, eating, living, thinking. Energy is spent, order is decreased, and entropy increased by that process...but something else also happens. That process performed by the Human costs entropy, but also the scattered distribution of those bits of energy in nature are collected and concentrated into that singular system which is that human being. That concentration of energy can be arranged into a complex structure within the human being's understanding, relations to nature, and behavior. Although the entropy of nature was increased in order to yield this higher state of complexity manifest by the human agent, that higher complexity state of energy is more complex than what would have occurred if nature just took it's path without that process increasing its entropy or if that same entropy was added by a process which did not involve agency. So in this context, processes in nature driven by potential energy loss can break order up into less order, nothing else is involved and the only result is that potential energy is consumed and entropy is increased. That natural system has more distribution and detail afterwards, but the process is no more complex than any before it and does not add complexity. It is just governed by Natural Law. Also, the more fragmented and distributed arrangement of matter resulting from that specific system's natural entropic process, makes the total mass of the once orderded system less available to the workings of gravity to hold it together, and more susceptible to the effects of dark matter to push it apart.
      On the other hand, if an entropic system process involving agency occurs, loss of potential and increase of entropy can yield an arrangement of complexity exceeding the process of natural law. For example, memory and writing can provide a way to achieve the result only discoverable by a long and costly entropic process, and send that complexity as information into the future so that the result can be re-produced again later without repeating that massive expenditure of entropy again, as would have been necessary under the complexity of natural law only.
      This property of agency to yield higher-complexity arrangements of energy from entropic process, and use them to overcome the entropy penalty and total increase of entropy over time that nature would dictate necessary under natural law... Is something which has never been observed by us before in the entire history of the universe.

    In the realm of quantum mechanics, time isn’t an absolute, flowing entity but rather a dynamic, interconnected part of the universe's fabric. Black holes, with their immense gravitational pull, warp spacetime to such extremes that time itself seems to slow down near their event horizons. To an outside observer, a clock approaching a black hole would appear to tick slower and slower, almost frozen in time as it reaches the event horizon. Yet, from the perspective of that clock or an observer falling into the black hole, time would continue normally until they cross the point of no return. At the quantum level, where particles flicker in and out of existence and uncertainties rule, black holes present an even greater paradox. Quantum theory suggests information can never be destroyed, yet black holes appear to swallow all information beyond retrieval. This is the famous "black hole information paradox," a clash between quantum mechanics and general relativity. As scientists explore ideas like Hawking radiation and the potential for black hole evaporation, they inch closer to a deeper understanding, hinting that black holes might not be the end of time or information, but a gateway to quantum mysteries still waiting to be unraveled.

    De Sitter Space, can be tricky to describe. Where expansion occurs everywhere, equally. You could imagine, it's a series of nested regions, where we occupy, one of the innermost zones, with larger scales surrounding us. It is, a key concept discussed here. Something which some, may benefit from, incorporating De Sitter Space into their thinking, particularly when thinking on cosmic scales. It's important to keep in mind, being not hypothetical, but having been shown to be, reality. Which changes the way in which everything is relative in 4D spacetime, especially to us on Earth, being at an inner region, within De Sitter Space. Like Dennis Sharma, once taught Sir Roger Penrose a lot about humility, Sir Roger Penrose, taught me the same. Truly a remarkable man!

    I appreciate Penrose’s Occam’s razor approach to the universe, not proposing so many things that we cannot observe to explain the problem.
    No doubt, the universe is only as complex as it is and it might still be wildly more complex than what we presently observe.
    Whether that means multiple Ions or unseen dimensions & energies we can only speculate about.
    Regardless, I appreciate also Penrose’s focus on physics being connected to physical observation and not merely mathematic speculation.
    While fantasy is necessary for imagination, without observation, there is no way to know if fantasy is merely fantasy.
    Plato imagined a realm of ideas, where the ideas existed independent of matter; the Christians imagine God; the String theorists imagine other dimensions.
    All of these ideas are beautiful, but none can yet match the physical potency of the earlier age of physics, which brought the physical power of a sun to the surface of the earth.
    Without physical evidence, we have a real problem here; we have no physical force to manipulate, no physical result to show.
