I gotta say that I'm right there with him on information theory being a key to understanding life. Most things that store and replicate information have oddly life like behaviors. And from a universal perspective all life that exists in the universe has a direct informational chain of cause and effect that goes all the way back to the begining of the universe.

Totally agreed. I really like that way of framing the idea of life. It expands nicely beyond the limitations of trying to define life by being carbon-based or involving chemistry that uses other elements in the same way we use carbon (drawing a line thereabouts has always seemed awfully arbitrary to me), and also it neatly ties up and puts a bow on the question of whether viruses are alive. No more ambiguity. Does the matter go through chemical or physical processes involving transmission of information instead of just purely physical (either gross level or molecular/atomic level) reactions? Bam, it's alive. Then the only fuzzy line relates to "artificially" created engineered things that could fit under that umbrella, like computers. Which I think fits, I mean, I think it'd be healthiest if we'd all start framing AIs as life, with limited AI being simply non-self-aware life, life that can't make real decisions of its own. That seems to be to be a good ethical foundation for linguistically forming how humans relate to AI as it develops. I like this, I'm adopting this.

Highly recommend. There really isn’t enough time to ponder the questions of the universe in one lifetime, but research and listen for hours upon hours and always be fascinated. Keep up the great work Mr. John.

There is no [permanent] alternative to Creation. The physical universe is an alternative to Creation, and that is why it is changing and moving, for it has a beginning, a middle and an end. You are somewhere in the middle in the great span of Creation. Only a very small part of Creation is involved in manifest life. But to you, of course, it is immense and incomprehensible, as it should be. It is not possible for your intellect to comprehend the scope and the magnitude of this. For you, Creation is the physical universe. It seems to be forever, but it is really temporary. It has a beginning, a middle and an end. You have not even reached the middle spot of this expanding universe, so this is something that is confounding to your understanding. Both of these powerful quotes are from a book The One God, by Marshall Vian Summers.

My parents witnessed a meteorite strike the earth on a camping trip in the 70s. It was too hot to touch when they found it so they scooped it up in a coffee can. Keeping it in a fishing tank for years because of the pretty color. When I heard this story as a teen I searched for it and found it stowed away in the garage. I used an old tungsten carbide industrial planer blade and a sledge hammer to fracture a piece off for testing. I was told it was specular hematite and that is indeed what it appears to be. So my question is were my parents mistaken in their account? Is there some way this piece of hematite was ejected and returned to Earth? It does appear to have some heat marks or something that all other hematite I've seen lacks. Maybe it was just somehow involved in a tiny impact event? Was it maybe just launched from a thermal event only to reenter the atmosphere in view of some campers? Whatever the case it was always a fun story for me so I though I'd share and ask for some opinions.

It's actually weird that the volcanic vents exist at all. If one or two values were slightly different, then matter itself couldn't exist in this universe. And even then, if there wasn't just a slight asymmetry between matter and anti-matter, again nothing would exist. And even then, conditions in the universe had to be just so, ever so slightly, for matter to begin to clump together. Had that been ever so slightly off, nothing would exist. This list goes on and on before getting anywhere close to life. That it made it to life and intelligence is really just icing on the cake.

fun fact(s) by tracing back conserved core genes among all extant organisms it suggests that LUCA(the Last Universal Common Ancestor) was an organism which metabolized iron ions fixing carbon through something called the Wood-Ljungdahl pathway. In other words it depended on dissolved iron to both fix carbon(chemosynthesis) and access chemical energy(respiration aka breathing) It is important to note that even today much of Earth microbial biosphere still relies on metal ions for chemosynthesis and respiration. Even the oldest metabolic machinery to use dissolved gasses rather than metal ions i.e. those organisms which use Sulfur are most abundant in and around hydrothermal systems. Even photosynthesis which we tend to associate with oxygen seems to have evolved early on within photoferrothroph bacteria which at least today utilize Bacteriochlorophylls (the group of photoreactive pigments life uses to fix carbon storing chemical energy from sunlight in various sugars. Closely elated to them there is a another important anaerobic group of organisms developed another way to fix carbon from sunlight using hydrogen sulfide also utilize Bacteriochlorophylls though notably both of these paths are in terms of carbon fixation compatible as the waste products react turning into insoluble pyrite a process which in the absence of oxygen can be a closed cycle. Aerobic photosynthesis is probably a result of a tweak to the hydrogen sulfide reaction trading out hydrogen sulfide for the much more abundant water resulting in O2 as a waste product. The catch here is that it requires more energy to break apart water molecules than it does to use other photosynthetic pathways so this is actually the least efficient way of fixing carbon of the 3 main photosynthetic pathways. This inefficiency at photosynthesis is ultimately the consequence of the very same reason that makes oxygen so good for respiration enabling multicellular life the extremely large oxidation number of Oxygen. For reference oxygen has the highest of all non Nobel gas elements 4th highest if Noble gas cations are included. The oxidation number's magnitude determines how much energy an organism needs to invest to trigger a reaction in either direction. Life doesn't seem to care if the reaction is oxidizing or reducing as in either case the reaction itself can be flipped around to provide energy one way and take energy the other way. What matters is the magnitude of the reactant which is sort of like the weight it pulls in chemical reactions. This always favors the release of stored energy i.e. the process which stores energy must provide energy obviously and a system tends towards its lowest energy state. The more effort it takes to metaphorically push it up the chemical hill the more you can get back when it falls down. A bigger push "uphill" requires a higher initial investment of energy. However as the end products organic molecules are the same this means the net effect is the quantity you get out the other side for a given amount of effort. As a consequence it seems the billion year delays between the invention of aerobic photosynthesis and the large scale oxygenation of the ocean are likely caused by natural selection favoring sulfur and iron based photosynthetic metabolisms, which are easier to perform give less energy in return, as they get to consume more resources more quickly. More importantly as the energy investment threshold for phototrophic reactions is quantized meaning a photon must have sufficient energy to drive the reaction or it will not occur. As light diffuses out more and more with depth this means anaerobic photosynthesis to be biologically sufficient both occur lower down in the water column compared to aerobic photosynthesis. This is relevant as in the open ocean far from land diffusion drives access to essential nutrients most importantly Phosphorus. The more biological reactions the more resources are depleted which means less and less nutrients get to diffuse upwards from the seafloor with depth. Thus for oxygen metabolism to win i.e. produce an accumulating amount of oxygen you need nutrient scarcity to not be a problem in order for it to build up to concentrations where its high toxicity matters. www.nature.com/articles/s41467-019-10872-z The conditions where local oxygen accumulation is favorable thus are restricted to either extreme influx of nutrients injected into the system such as Large Igneous Provence's particularly rich in Phosphorous, and or more importantly shallow water and or costal waters where aerobic photosynthesis can succeed at or near the seafloor. As the first geochemical evidence for any significant exposed land mass is roughly 3 billion years ago it isn't surprising that the first appreciable oxygen accumulation was a brief short lives window around 2.9 billion years ago where polar glaciation was able to occur. The nest time there was any significant evidence for land seems to be right around the onset of the Great Oxygenation Event and the subsequent Huronian glaciation 2.4 billion years ago aka the 1st snowball Earth. Eventually after around 300 million years the planet was thawed and the system had by 2 billion years ago settled into a steady rate of a few percent of oxygen after a brief spike known as the Lomagundi Excursion Event, where rates climbed into double digit percentages also coinciding with the first clearly macroscopic multicellular organisms of some affinity the Francevillian biota. From that point on up until 720 million years ago aerobic life was probably restricted to shallow costal or fresh water environments with evidence for prokaryotic extremophiles colonizing the land to some degree. Among this life were the first Eukaryotes which likely appeared around 1.8 billion years ago and rapidly diversified within the aerobic biosphere. Then something happened at around 720 million years ago that changed the equation. A large amount of phosphorus came from somewhere the leading suspect being the Franklin Large Igneous Province a phosphorus rich flood basalt LIP associated with the break up of the Supercontinent Rodinia. Regardless of the cause the planet froze over once again as oxygen levels soared in a boom bust manner with a series of episodic global glaciations the first of these the Sturtian glaciation was the most significant, followed by a second Marinoan glaciation both of which involved glaciation of areas that paleomagnetic records indicate were equatorial there was then a third almost snowball glaciation the Gaskiers glaciation which extended to midlatitudes nearly as low as 30 degrees latitude. rocks dated only 9 million years younger start the first appearance of the Ediacaran biota and the last snowball style glaciation. Hmm I wrote a lot more than intended... well hopefully it is informative... Might modify this into a blog style post w/ more citations

Love this channel but being able to listen via podcast would be way better than the dumb YT app, which won’t allow background playing. Is there an audio version of this show? If not there really should be. I think you could automate the whole thing, and not add any additional workload.

Face it, you need infinite possibilities within limited time and space. It's the definition of impossible millions of times over and that is just for the information that already has to have the structure that it has written programming for. You need information for the structure and you need structure for the information. Then you need the same thing all over again for each and every different organism, not to mention a compatible environment.

Dear Channel. is it matter of respect to your auditiory to take care of quality of audio? such big difference between Paul Davies and John Michael Godier recorded speech. for shure, there are some equalisation medhods that could make the guest voice more readable. being not native speaker it is hard to brake through this wall. Thanks for your work, anyway. but please...

Awesome metaphor. I think it was Greg Graffin from Bad Religion who said that the more knowledge we identify in the universe, the more gaps are naturally created between all established discoveries, and so the more we come to know, the more there will be to know, in an infinitely expanding way. Your numbers metaphor really perfectly matches that exact concept of infinite subdivisions of a seemingly finite space.

Also another way to explain why it is right for life is because whatever properties and processes that belong to this universe produces outcomes such as life that you see exist, and no further explanations are needed. It's not as if there was a choice for whatever outcome materialized. Always follow the logic and the answers will arise from that logic. Also the answer is contained within the question

"Shams and delusions are esteemed for soundest truths, while reality is fabulous. ... In eternity there is indeed something true and sublime. But all these times and places and occasions are now and here. God himself culminates in the present moment and will never be more divine in the lapse of the ages." Thoreau put the best words to my same thoughts on this. The more we learn about the incredible depth and complexity and amazingness of the universe, of course the more reverent we'll become of it. It's just truly too vast for us to deeply comprehend. It makes sense that humans would try to interpret it through a human-influenced lens. But yeah, I don't think a bit of subjective spirituality flavors in your personal poetry/metaphors/aesthetic you adopt in your mind is AT ALL in conflict with being scientifically literate and also respecting that the rules of the universe are as mundane and basic and straightforward as they are glorious and magical. It's totally both. Humans have always interpreted the most complex, abstract, mind-blowing things by creating about them. When we have a new idea, we create words for it so we can wrap our heads and our literal mouths (or other word-organs like hands) around it. When we have emotional experiences, we create expressive art of all kinds about it. When we have spiritual experiences, which I'd say includes contemplating science and the universe, we create spiritual metaphors/lenses about it. Sometimes that looks like religion once people add rituals and moral sets to those lenses, and sometimes it just looks like a chill naturalistic spirituality where you know you're in a truly natural universe and all things can be explained rationally but also appreciate that it's incredibly cool and meaningful to be here and spend thoughts on wondering about that meaning. I think it's all healthy as long as people stay flexible and grounded and keep in mind that subjective lenses are just that, subjective lenses, and that our rituals and feelings about them are just our own personal aesthetic just like our own taste in music or food. It's all your prerogative how you want to experience the universe, including how you experience your place and purpose and unimportance and importance in it. That got rambly lol whoops, thanks for coming to my "naturalistic science-mindedness and spirituality aren't mutually exclusive, dang it" TED talk

If life isn't as old as the universe, then the universe can (best? only?) be understood without considering life (and especially consciousness) at all. Those would be incidental side effects.
