Physicist and cosmologist Paul Davies, author of The Demon in the Machine, argues that the deepest mystery of life’s origin is how chemistry came to write its own code.

Davies traces the question from Aristotle and Schrödinger’s “aperiodic crystal” to Maxwell’s demon, Michael Levin’s two-headed flatworms, and the possibility of a shadow biosphere hiding on Earth.

About Paul Davies:

Paul Davies is a theoretical physicist, cosmologist, astrobiologist, and bestselling author. He is Director of the Beyond Center for Fundamental Concepts in Science and co-Director of the Cosmology Initiative, both at Arizona State University. Previously he held academic appointments at the Universities of Cambridge, London and Newcastle upon Tyne in the UK, before moving to Australia in 1990, initially as Professor of Mathematical Physics at The University of Adelaide. Later he helped found the Australian Centre for Astrobiology in Sydney.

Davies’s research focuses on the “big questions” of existence, ranging from the origin of the universe to the origin of life, and include the nature of time, the search for life in the universe, and foundational questions in quantum mechanics. He helped create the theory of quantum fields in curved spacetime, with which he provided explanations for how black holes can radiate energy, and what caused the ripples in the cosmic afterglow of the Big Bang. In astrobiology, he was a forerunner of the theory that life on Earth may have come from Mars. He is currently championing the theory that Earth may host a shadow biosphere of alternative life forms.

Davies has lectured on scientific topics at institutions as diverse as The World Economic Forum, the United Nations, the Commission of the European Union, Google, Windsor Castle, The Vatican and Westminster Abbey, as well as mainstream academic establishments such as The Royal Society, The Smithsonian Institution, and the New York Academy of Sciences. Davies devised and presented a series of 45 minute BBC Radio 3 science documentaries and a one-hour television documentary about his work in astrobiology, entitled “The Cradle of Life.” Among his bestselling books are “The Mind of God,” “How to Build a Time Machine,” and “The Goldilocks Enigma.” His latest book, “The Eerie Silence,” was published by Houghton Mifflin Harcourt in 2010.

    Davies saying the deepest mystery isn't just that chemistry happened, but that it somehow learned to write its own code, really stayed with me. And ending with Wheeler's delayed-choice experiment felt right, because it hints that observation and origins might be more tangled than we like to admit.

    He's missed Assembly Theory from Lee Cronin, Sara Walker et al wrt to a 'Life Meter', it uses high complexity index and high replication numbers, this is unique to life. Turns out the Chemists are aligned with his thoughts. They go one further in that complex chemistry has tendency to form stable complexity using predecessor 'index'

    What about the Receptor Theory of Consciousness? Many examples from medicine and pharmacology demonstrate that drugs and toxins can alter our consciousness. What about a new understanding of how our biological receptors work? Perhaps the physics of receptors is the missing ingredient for understanding ourselves? At the most fundamental level, we are the summation and interplay of trillions of our cellular receptors. These receptors are poised biochemical balances that interact with our environment and with one another in a grand symphony that has evolved since the universe began. We are currently unique beings who can reflect on the universe and discover our origins within it. We reside upon the cusp of an unfolding creation, like a surfer trying to catch a wave. See the book, Origins of Life's Sensoria, for more.

    "The laws of the universe are unable to explain these origin mysteries"

    The "laws" of the universe is just our description is how universe works. To say that how universe works is unable to explain how universe works is to claim that the universe is one big self contradiction. It's a claim that is not even wrong, it's total, unadulterated nonsense.

    One can say that, at present, we do not fully know how X works. In fact, that's what we should say to be honest if we don't fully know how something works. That's it. Making magical assertions beyond that, such as:

    1) We will never know how X works
    2) We can never know how X works
    3) Nobody can can ever know how X works
    …
    N) X works by magic

    are ALL nonsensical bullshit claims, but in some sense, are INCREASINGLY nonsensical claims. Any so called scientist making these assertions is NOT doing science, but is engaging in magical bullshit.

    I am a physicist, and I would like to explain why science leaves no room for the possibility that brain processes could be a sufficient condition for the existence of consciousness, which means that consciousness cannot be just a product of brain activity and naturalism fails completely in any attempt to justify the existence of human consciousness. It is a scientifically established fact that a conscious experience is associated with an enormous number of distinct microscopic physical processes occurring at different locations. As I will explain, there is no physical entity that connects all these distinct microscopic processes. Therefore, the existence of conscious experience requires a connecting element that is absent from the physical laws. This missing connecting element can be identified with what has traditionally been called the soul (on my YouTube channel you can find some videos providing a more detailed explanation).

    The central idea underlying naturalism is that complex systems (such as the brain) can generate new properties, commonly referred to as emergent properties. In reality, such emergent properties are merely subjective cognitive constructs that depend on the level of abstraction and simplification we choose when analyzing and approximately describing the underlying microscopic processes. Emergent properties are, in fact, properties of conceptual models based on approximations, simplifications, and subjective criteria that lie outside the physical laws. They do

    not exist in physical reality, that is, the reality described by the fundamental physical laws, but arise from the approximations and subjective elements introduced into our descriptions. Identifying conscious experience as an emergent property therefore amounts to introducing elements that are

    foreign to the physical laws, thereby contradicting the fundamental premise of physicalism itself.

    To clarify this point, let us examine the definition of an emergent property.

    An emergent property is commonly defined as a property possessed by a collection of elements that is not possessed by any of its individual components.

    The crucial point is that a collection does not exist as an objective reality, since grouping elements into a collection requires the subjective choice of which elements are to be included. Defining a collection amounts to drawing an imaginary boundary that separates certain elements from others. Such a boundary has no physical existence; it is a mental construct based on subjective criteria that are independent of the fundamental physical laws, which describe only the interactions among elementary particles. Furthermore, grouping elements into a collection does not eliminate the fundamentally discrete nature of the collection itself. Physically and objectively, only the individual elements themselves can be said to exist. The same reasoning applies to temporal sequences of processes: determining where a sequence begins and where it ends is likewise a subjective decision and viewing the sequence as a single, global process does not erase the fundamentally discrete nature of the sequence itself.

    Consequently, any property attributed to the collection as a whole depends intrinsically on the mind, since it is tied to the subjective choice involved in defining the collection itself and regarding its elements as a unified structure. Subjectivity is therefore a necessary precondition for the existence of any emergent property, and consciousness is, in turn, a necessary precondition for the existence of subjectivity. This argument is sufficient to show that every emergent property presupposes a conscious mind that conceives it. Consequently, the mind itself cannot be identified with an emergent property.

    The brain, considered as a single entity, is merely a conventional cognitive construct based on separating a group of particles from everything else and then treating those particles as a single entity. The conceptualization of the brain is based on subjective criteria that are external to the laws of physics. In reality, there is a continuous exchange of molecules with the bloodstream, and when and how such molecules begin or cease to be part of what we call the brain is determined arbitrarily.

    An example helps clarify this point: the concept of a nation. A nation is not a physical entity and does not refer to a mind-independent entity, since it is merely a collection of people grouped together according to conventionally established criteria. Conceiving of these people as a single nation does not erase their fundamentally discrete nature: they remain distinct individuals.

    The same applies to the brain: its actual physical structure is fundamentally discrete, and treating it as a single entity is purely a subjective abstraction.

    Brain processes are likewise fragmented. They consist of an enormous number of parallel sequences of microscopic physical processes involving distinct particles located at separate points. There is no direct connection between the individual locations within the brain, and such connections are merely subjective abstractions used to approximately describe sequences of many distinct microscopic processes. Objectively speaking, there is no single global process but only an enormous number of local microscopic processes, and treating all these processes as a single event is merely a subjective abstraction. The lack of a physical connecting element between these billions of microscopic processes implies that conscious experience cannot exist as the result of brain processes alone.

    In science, we develop approximate models to overcome the limitations of our cognitive abilities. Such approximate models are merely products of the human mind. Indeed, an approximation is nothing more than a cognitive construct rather than a mind-independent reality, because a mind-independent reality is exactly what it is and cannot be an approximation of itself.

    Using a simplified model instead of a more accurate one may introduce fictitious properties that are absent from the solutions provided by the more accurate model. It is analogous to having two photographs of the same object, one sharp and the other blurred. If we wish to determine the object's real properties, we must rely on the sharp photograph; the features visible only in the blurred photograph (such as indistinct patches of color) and absent from the sharp one do not correspond to actual physical properties of the object. Clearly, the object's real properties do not change simply because we have chosen to reduce the resolution of the photograph. In this analogy, the sharp photograph corresponds to the fundamental physical model, whereas the blurred photograph corresponds to the approximate model. The blurred patches represent emergent properties, which are not genuine properties of reality because they are merely artifacts introduced by approximation and simplification. An approximate description does not reveal any new real properties beyond those already captured by the more accurate description; it merely introduces "blur." For this reason, if we wish to understand physical reality and its genuine properties, we must refer to the fundamental physical laws rather than to the distinctive features of their approximate and simplified models.

    Assuming that emergent properties are mind-independent amounts to committing the map-territory fallacy, that is, confusing a simplified representation (the "map") with the reality it represents (the "territory"). In this analogy, the underlying microscopic processes constitute the territory, whereas emergent properties constitute the map, that is, the simplified conceptual models we use to describe those underlying microscopic processes in an approximate manner. The error is particularly serious because, despite having access to far more accurate "maps" (the fundamental physical laws), naturalism chooses to disregard them in favor of much more simplified and approximate ones.

    Conclusions

    My arguments show that physicalism is incompatible with one of the most fundamental aspects of scientific knowledge (the discrete nature of molecular and biological processes) and that brain processes alone cannot constitute a sufficient condition for the existence of consciousness.

    Since conscious experiences are associated with many distinct microscopic processes occurring at separate points, it is necesssary that a connecting mind-independent element exists and that such element collectively interprets all these distinct processes as a unified conscious experience. Such an element must exist independently of the mind and therefore can only be intrinsically indivisible, that is, elementary. This indivisible element cannot be of biological origin because the physical laws describe no physical entity possessing the required properties.

    Thank you so much for this. You refer what I’ve been trying to explain to people that climate change is not a result of burning fossil fuels. It’s a result of us destroying the very components of life which arrived at a certain level of complexity to be able to work in conjunction with climate patterns and do establish and maintain the stable atmosphere that we take for granted. In order to mitigate climate change the only way forward I believe and reinforced by this is to work to reestablishing as much varied life as possible on as many places in the planet as possible to repair the hydrological systems and to reestablish a balanced climate by de animating our planet we’re actually causing our own demise by destroying the balance between life and the climate which it is in relationship with

    How were the first humans made? And is our consciousness saved after we die? That is the question. Seems possible to create biological drones able to record in all different senses and that can reproduce on their own. Makes me wonder if Humans have been here all along and we have gone through many apocalypses and realized we needed to pump the oil out of the Earth to stop it from burning to a crisp this time. We might be a species that travels the entire universe planting other humans to breed and strip the planets of all their resources. Maybe we were sent to Earth to discover everything and strip it down to its core before our creators come and take us to the next one.

    53:15 Gotta throw a flag here. It's already been clearly established in this talk that life is well beyond our capacity to understand right now. As such, It's quite inappropriate to slide into the role as a life specialist and rule on the question of whether or not a tweaking of universal fundamentals may/may not effect the probability of life arising in a subsequent reboot. We're not life specialists. Nor do we even have a unified theory of physics. Of all the fundamental attributes of our universe that we currently know of, there are quite a few that do have wiggle room. So the answer is a firm "We simply don't know."

    I like the idea that there might be millions of primitive or almost life forms zooming around inside rocks waiting to hit a planet suitable for it to live on and maybe become a much higher life form.😊

    Gotta say, was sad when he said "quantum computer AI – Q AI could 'explore all quantum possibilities" since we know this is not how quantum computers work. Luckily was at end and clearly not his field, but its the whole "heard a great 2 hr symphony and a kid screamed at min 115 and ruined it all" lol

    It's clarified in the Open Tensoriality and the Cognition-Cosmology Equivalence Principle. Info is stored in the software (Symboliad as structural concept). Physics of physics is explained by the equivalence in which we partition the universe (same as the worm is cut, that's what it partitions through its Symboliad.) This then gives cues of now the search for aliens is not a physics problem.

    The universe develops increasingly complex reference points through physical relationships, eventually producing biological systems that maintain themselves and conscious systems capable of constructing internal representations of reality across time.
