Has the second law of thermodynamics finally been proven?
The second law of thermodynamics has been shrouded in mystery for a century and a half. Now, after building on the recent breakthroughs in the foundations of physics, Stephen Wolfram has finally provided a resolution to the mystery.
Stephen Wolfram is a computer scientist, physicist, and businessman. He is the founder and CEO of Wolfram Research and the creator of Mathematica, Wolfram Alpha, and Wolfram Language. Over the course of 4 decades, he has pioneered the development & application of computational thinking. He has been responsible for many discoveries, inventions & innovations in science, technology, and business.
In this in-depth interview, he shares his findings, shines a light on some of the most misunderstood concepts in physics, and answers some of our most pressing questions about the nature of the second law, entropy, and the dark side of the universe.

I wonder which Steven does? Also it strikes me that when he mentions "possible histories" that literature has pioneered this . What is a book of fiction? There are millions of duplicate paradigms. The venturi effect is reproduced no matter what the material that flows . Space, and carburetors, black holes... ? Have that shape? The flow speeds up. Of course there are "possible" histories. Of course the flow of electrons, air, water, plasma speeds up when it is "venturied" lol. Scientists need more generalisation. His explanations of space and time are awesome.

    Wow. This is the best physics interview-podcast I’ve seen since a long time. Happy to see Stephen is now translating his mathematical insights into unconventional physical interpretations. We badly need this, as our current 100-year old physical theories (GR, SR, QP) are based on mathematical correct approximations, but incorrect underlying equivalence relations. There are many things Stephen guesses correctly; such as dark matter actually being a yet unknown property of space. Bravo! Indeed. Finally someone who gets that we need to focus on the grid itself, not on some imaginary invisible mass. Actually the erratic erratic galactic rotation curves are the result of a LACK of spacetime in between our spiral arms. But again; happy at least the discussion is on the grid itself! We need these disruptive insights of top people! Another mathematician, Roger Penrose, made a similar deep remark, as he stresses time and again that mass fundamentally equals not energy but inverse time! In his words; ‘…If you have mass in the QP world, you have a CLOCK…’. He realises this by substituting Planck E=hf into E=MC2. To finish things off, Heisenberg already defined the other CORRECT inverse relation, namely Energy equals inverse space as per dXdP>=h/2, a polar notation constant. Do we know see what is going on? Why we fumbled for 100 years? If we take these two correct inverse equivalence relations, then Einstein’s SR now says that a speeding object contracts frontal space and time, resulting in an INCREASE in its energy (inverse space) and mass (inverse time). In in slightly different terms; the speeding object wraps continuous ST fieldlines around itself in a standing wave of a discrete quanta of inversed spacetime windings, giving the object potential and inertia. Now do we see that speed induced effects on spacetime on the one hand and energymass on the other all cancel out? Want more proof? Stephen wants to know where complex number come from in the QO world. Well, we must compensate [m/s] speed with its dual QP equivalent speed expression of [J/kg] or [J/kg=Nm/kg=m2/s2]. So, the only way m/s and m2/s2 cancel out is to use a prefix of i2=-1 at the QP side. So dual inverse physics requires math to have complex numbers. Do we now get it?

    While I have tremendous respect for Wolfram's many accomplishments, most of the ideas that he talks about here do not originate with him. By the way he talks about things, it's easy to mistakenly think it's mostly his work and ideas, rather than the collective work of generations of scientists. I wish he presented things a bit more modestly so that casual observers get a better perspective. In terms of his work on computational irreducibility, it is an interesting perspective, but these ideas can also be framed equally well in more traditional mathematical physics terms.

    The way he thinks about computation being a limited resource rhymes with how I think about the speed of light being a hard limit on motion. A particle cannot move faster than with the speed of light because it runs out of time to move even more quickly. More generally, the speed of light is really the speed of causality, so it tells us how fast the process of applying the rules is running.

The best analogy I can make is of a man creating the tools to work stone to ultimately build a cathedral. The dogged pursuit of his vision of understanding reality in ways no one has done before is amazing. I do not begin to understand his work in a meaningful way, but I have to believe, that if he lives long enough, he will build that cathedral. If he succeeds the consequences for our understanding of reality are profound. If he fails, he will still learn amazing things.

    Wolfram is undoubtedly one of the most brilliant minds alive in the last few decades. His current slew of presentations are intriguing, but it would be nice to be shown some actual maths, algorithms, explanations, or (heaven forbid) testable predictions from his work. The fact that he's not tied to academia gives him a lot of freedom, but freedom to work also means freedom to utterly ignore the scientific process and just go on podcasts to claim he's solved all the problems without actually telling us HOW, in a way that can be understood, scrutinized and replicated.

    That is a pretty good definition of time. From my physics, nuclear and mechanical e, background… I would say time is the change in relationship between physical things. This incorporates the computational steps Wolfram suggests but also includes the notion that if there was nothing physical in the universe, then we don’t have a universe and we don’t have time.. just having a potential energy of no form existing and not changing would be a state where time does not exist.. no one can know if that state ever existed before the Big Bang. 1/x^2 vs 1/x discussion.

At 0 K all motion stop. If molecules move, they possess energy, kinetic energy. If they have energy, temperature must be higher than 0 K. So I can agree that second law have a boundary, but as I understand, it is related to temperature. Can someone help me out here?

    Well I'm not him but I think I can take a stab. I think the point he's making is that they are only related in the fact that they are emergent properties of a system that has matter. Temperature doesn't make any sense outside of having matter interacting with other matter. While entropy itself is a much lower level conceptualization of there being states of the system that change over time and what the rules of those states tend towards. They aren't tightly coupled as concepts and it's not obvious that either one requires the other perhaps.

Actinides decay that is true, but that is caused by them being created by interacting with other matter (neutrons) thus becoming radioactive. Trying to keep up with Mr Wolfram is hard. Maybe harder than the capability of my intellect, but I will give it a try. Entropy of matter can only be caused by two things. Chemically or kinetic interactions. The result is the same. Alteration in energy states that manifest into lower equilibrium. If this is true, then temperature is related. I have to confess that I am grappling here. Maybe I miss something. What role does photons play? Let's ask; Gamma radiation dependent on temperature? No. It moves in 0 K space. What happens when it hits matter? Energy transfer if it hits a nucleus. Result? Increase in temperature. Same with lower frequency radiation. EM radiation causes temperature increase and alpha/beta radiation does to. Am I in the woods here?

    Entropy is a higher level concept in itself caused by irreducibility. The farther away one is from the beginning of when the rules started; the more “encrypted” they are due to the complexity of the rules that have been applied over each iteration. Pseudo example For n in 100: If n modulus 3: 2+3^n Else: 2+ 3^n*2 Is less complex than For n in 1000 The reason why that causes more entropy is because there’s more information to unpack. Hence, the concept of “uncertainty” and “chaos” are historically used. Temperature is what we subjectively experience but it seems more like it’s related to the density of the functions that are being applied as entangled rules. The lower temperature indicates there’s less rules being applied to the system

Take into account special relativity and the seemingly limitless size of the universe then for any proton/electron to view all other matter in a state of entropy would require all matter to have always existed in a state of entropy otherwise the forces of gravity/magnetism/light energy would still be affecting it (from afar) and that would also flow back.

I suspect the moment we observe and we confirm the observed particle was left spin and the unobserved will be right spin particle, I suspect the universe is not transferring any information between particles rather the moment any one of it is observed at the same time they both are being materialize of same spin instead of opposite spins, there is no possibility of information transfer rather generate the same out put for both situation, whether you choose to observed chosen particle or you chose to observe destroyed particle, you will always find same outcome, if let say you chose to see a particle and concluded it was left spin , i insist if you skip that particle and try to observe it's entangled particle which you was not observing before, you will be surprised to find that even that spin is left, so despite its entanglement particles but universe has decided same spin for both particles at same time and put restrictions that you can only observe one out of these two. The basis of my argument is a religious text book and some personal experience of reality.

I'd be more amenable to the possibility that we don't have a right understanding of gravity or time, or that we don't understand how large distances affect our observations of distant events in respect to time, or whatever, than that the bulk of the universe is made of some otherwise completely undetectable matter, that somehow amazingly seems to have no measurable effect on our experiments done here on earth.

Secondly, the cosmological constant isn't thought to change over time as far as I know. Thirdly, I believe the concept of Dark Energy and the cosmological constant actually would work quite nicely with Dr. Wolfram's approach. I don't think he's trying to refute that. What he's trying to refute is that the universe is made up mostly of matter that can't interact with other matter except via gravity. He thinks that some fundamental process other than an undiscovered particle might be responsible for the odd behavior of galaxies. And he's extremely vague about what this might look like. I certainly wasn't very convinced from just this conversation.

    Wolfram is talking about computation and at the same time saying that entropy does not require for the concept of energy (24:35). Energy quantifies the system capacity to accomplish physical work. Without physical work, we cannot even know (compute) the entropy of the system! Entropy concept by itself only give us information about the current state of the system. However, what really matter is the entropy variation, which tells us about whether the system gain or loss information. To change the system information in just one bit, any computer machine must dissipate (at least) 2.9×10^−21 Joule of energy (at room temperature), which is called Landauer's principle (already verified with experiments) = k_B T ln 2, the Boltzmann constant by the system temperature by logarithm of 2.

If you are stationary, your velocity is pointed completely in the direction of time. Whereas when you move spatially, some of your fixed speed is spent on moving through space, and the time component of your velocity vector is decreased. In this context, what is speed of light in Stephen's model? Is it essentially an expression of the unit of computation resources used by a node to compute one step?

    The speed of light is probably the speed of computation in the model if I were to guess. I wonder why that would be the limit within this framework though? What dictates the amount of computation that can be done?

    @@6ixpool520 If we take the analogy with the velocity vector in spacetime, it is not just the maximum limit of computation, it is THE amount of computation done in every step. You can't go higher, you can't go lower either. So it would essentially be a (universal? local?) constant, a quantum of computation. And speed of light in space would be derived from it, a mere emergent phenomenon.

    The Second Law, like the First Law in their full generality are axioms of phyiscs. The conservation of energy is an axiom of physics. In its appearance in mechanics or in E&M, it may be "derived": energy is a constant of motion or an integral constant of a dynamical equation. That may be shown. Similarly, the Second Law may be shown for particular thermodynamic systems. But it is axiomatic in full generality.

    To simulate a vat of warm water you need a way to program it in a fluent time passing manner. This would basically be a pool-table simulation. In programming the issue is to make the time flow and not tick. If time in a computer simulation ticks it will be subjet to aggregating integral error. I wish he could go deeper in the programming aspect it self in how to consider a particle bouncing more than once in a single frame/update cykle. Is there an approach of doing this in so called (P) time? I have always thought you can only enter the computing of heat within the realm of (NP) it feels like (P) vs (NP) and Maxwells deamon is interlinked with the way we makes modells of heat.

    @1:10:26 Did he just say time dilation is essentially that, there is a certain bandwidth for processing movements (recreating yourself in another location) and the effect/passage of time, and if you move fast enough, you’re essentially causing more displacement calculations, taking bandwidth from time calculations, resulting in the dilation. Why was my first thought: “That’s exactly like setting off a bunch of TNT on a Minecraft server to tank the frame rate of the server, overload it with calculations so that as everyone else (the player observer) ages at the same rate, the server only processes a fraction of server time due to the explosion calculations”.

Will this lead to better design outputs of AI, or faster space travel or instant intergalactic communication, what say in some oblique future of theory of mind and self-aware AI, once the 'Emergence' has initiated and introduced new calendar time cycles for A.I.Sapiens 2.0 to observe, and outlying Sapiens 1.0 to terrorize.

    its not circular. Thats exactly what it means. Time, is the progression of a system changing states. when the system stops progressing, "time" stops. because the system is non-isolated, we dont notice this. say we have a system in front of us like particles in a box, and lets pretend we could stop all of its particles from moving. Well we observers of the system dont say time stops, because we humans as a system ourselves, has not stopped. The problem in defining time as existing independent of underlying processes, is a feature of us relying on us observing systems in isolation, which is not possible because we are part of the system. its a basic flaw in the assumptions of traditional physics, and also why theres an observer dependence in every major physics theory.

    I think that's the implication. He goes into how branchial space (the quantum waveform) reconverges and forms coherent structures (the waveform "collapse") in some of his other interviews. The maths is beyond me but what I gather from how he explains it is that being observers at the scale that we are, quantum mechanics is barely felt because the summation of the diverging branches across branchial space statistically evens out to a universe that has "collapsed" onto one state. Similar to how the pressures of gasses are "one number" is a statistical aggregation, and not the ground truth that each gas particle has its own momentum.

    The Maxwell's Demon paradox that Dr. Wolfram mentioned was proposed in 1867 and basically resolved with the advent of information theory in the 1940s. I wish he'd commented on that part. Basically, computation has some minimum amount of energy associated with it, as does measurement. In theory, if you knew the position, velocity, etc. of every molecule in a box, then you could predict how it will change over time. However, you would create much more entropy (in the universe, just not the box) than you've reduced simply through the act of computation. And as the system grows, the amount of computation grows exponentially faster. You can build a Maxwell's demon for a quantum system made up of a few entangled particles today, granted it takes a lot more energy than you could recover. But we could reduce it someday to a negligible amount of energy. However, for something the size of a small box filled with room temperature air, even with the theoretical maximum efficiency in information storage and computation, your computer would collapse into a black hole many many orders of magnitude larger than the observable universe.

    I think there's some incomplete reasoning going on here. Entropy is formally the log of microstates for a given macrostate. A higher entropy state therefore has more microstates. Since after any physical event the more probabilistic thing is the system acquiring a macro state with more microstates associated with it, entropy usually increases. For large number of particles, the number microstates of certain macrostates dwarf those associated by other more 'special' macrostates (think of a room with hot air on one side and freezing on the other) so much that the chance of entropy decreasing is infinitesimal. Probability seems to be a good enough reason why we don't have mixed freezing and hot rooms nor smoke combining with hot air and water vapor to become fuel. I don't see why the need to frame in terms of the computational boundedness of the observer. Even if we had perfect information about molecules we'd still see fuel turn to smoke and the temperature move from hot bodies to cold bodies for large objects. The second law is a probabilistic statement for which the macroscopic probability of violation is a limit tending to 0. When you have small enough systems you will see the other probabilities emerge.

    Some interesting statements: min 24:38 Definition of entropy: How many different configurations are in a system. Described by two to the power of a large number = exponent. The logarithm gives me the exponent and that is what entropy means. The concept of entropy has nothing to do with energy or temperature. min 15:08. What is time? Time is the inexorable(not stoppable) progress of computation. You cannot leave out a step. In other words, for me, the future cannot be predicted. min 15:40 Time is a parameter in an equation. If you know the equation, you can calculate the position of the planet at any time. But then he talks about computational irreducibility. This means that you can not calculate back to the original position of a particle. min 17:00 Computational irreducibility says that you cannot cheat the passage of time, you cannot jump ahead by using a smarter computer. -->This does not sound very intuitive, as we all try to get a better weather forecast. Otherwise, it is good to know that the future is not predetermined and predictable. The proof for "Computational irreducibility" is missing for me or I don't understand it. min 21:42 Heat is the randomized motion of molecules. min 23:17 My aphorism is,: "dark matter is the caloric fluid of our time" --> Maybe min 22:10 The second law is essentially a computational statement that start simple to describe, will typically become complicated to describe. It's kind of like encryption.
