150 years ago, many physicists thought that everything important has already been discovered, and all that remains is more and more precise measurements. And then Planck tried to resolve the "Ultraviolet Catastrophe"... The point is, nobody can predict what new physics can do, or how it can be applied, until we have discovered it.

[@mikemondano3624]

I think the most straightforward application for a breakthrough in physics would be smaller and faster transistors, and I am not talking about quantum computers. Modern semiconductor tech has to fight against quantum affects in both malfunctioning and operation. Fun fact, flash memory is based on quantum tunneling. The gate of a mosfet is physically sealed, locking it into a on or off state, then electrons are made to tunnel in or out of the gate to change state.

[@DarkShroom]

that breakthrough happens pover and over again, every time Intel or the chip manufacturers find a new process

[@brunonikodemski2420]

The problem is that all of the present quantum research is in the 20'K temperatures or way below like 4'K. Present FET and transistor technology is already limited by thermal effects, electronic wind, local tunneling, and quantum coupling between cells. 3 and 4 nanometer cells are getting to a 50% point in long term memory retention. 2nanometers maybe unattainable at room temperatures, and maybe susceptible to ordinary cosmic rays. Retention times for quantum machines is only in the few-to-dozens of microseconds range, at cold. Not even possible at room temps..

[@axle.student]

"Modern semiconductor tech has to fight against quantum affects in both malfunctioning and operation." Instead of fighting against the analog system wouldn't it be better to utilize it instead of trying to force it to be digital?

[@xxportalxx.]

​@@axle.studentone of the main benefits of digital signals is that they dramatically improve your Snr, you can largely ignore analog noise. In this case we're talking about signals so small the noise is of similar amplitude, using analog signals would only make this worse. It's like trying to yell accross a loud bar room, trying to speak normally is hard, so instead you use Morse code where you shout the dots and dashes, but if the crowd is louder than you it becomes hard to even distinguish those dots and dashes, what you're suggesting is that somehow going back to saying full words will make it easier to hear.

All microchips are "quantum", to a non-trivial extent. So at least in principle, the technologies and devices available in the microchip industry ought to allow us to access and manipulate aspects of quantum gravity, if and when we get a suitable candidate for experimental verification. So I speculate: if it is physically possible to create gravitational devices, they will be based upon nano-lithographic structures, and built by microchip manufacturers.

[@MPenzlin]

As far as I have heard: When Einstein realised that his theory would predict gravitational waves, he probably said that the effect was so small that it would never be possible to measure them. And vola: that is exactly what we are doing now. And he said that at a time when his theory was already finished. Now someone is saying that a theory cannot be applied before the theory has even been developed?? When I studied physics from 87 to 93: Blue LEDs are impossible Shortly before: Superconductors with a Tc greater than 35 Kelvin are impossible. It would be interesting to have a list of physical impossibilities that were actually possible...

[@shawns0762]

In some ways physics is going backwards. The concept of singularities is preventing clarity. G.R does not predict them. Einstein wrote in 1939 - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to dilation. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light". This doesn't mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Time dilation is just one aspect of dilation. Even mass that exists at 75% light speed is partially dilated. It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. Sound familiar? This is the explanation for dark matter/galaxy rotation curves. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 ultra diffuse galaxies including NGC 1052-DF2 and DF4 to have no dark matter. In other words they have normal rotation rates.

[@QuantumConundrum]

Well, certainly it's true that unexpected results have come, if I sit down and really think about it, blue LEDs haven't really changed my life the same way that say, electricity, or literally anything in all appliances that are used everyday. What you listed is a great example of diminishing returns. GPS accuracy to the meter is great, but centimeter or millimeter accuracy isn't nearly as useful... other than to blow up people in sandy countries. There are applications, just much more limited.

[@DJ_Force]

I think you are conflating impossible like breaking the sound barrier and impossible like breaking the speed of light. I don't think anyone thought blue LEDs would violate physical laws so much as no one knew how to overcome the engineering challenges.

[@patelk464]

​@QuantumConundrum maybe you should look at how many appliances you use everyday make use of blue led's before making such statement. As for cm accuracy GPS, this is already used by the military and will be important for unattended automation. As such it is likely to become much more important in everyday use in the future.

Your reflections feel like a call for awakening, not just in physics but in how we approach progress as a collective. The question, ‘What problem are we solving?’ resonates far beyond science-it challenges us to confront whether our pursuits align with deeper truths or merely distract us. This video reminded me of the importance of clarity and purpose in both individual and societal efforts. Progress isn't just about solving puzzles or achieving breakthroughs; it's about engaging with complexity in a way that brings us closer to understanding ourselves and our place in the world. Your call to contribute-rather than passively await solutions-is such a powerful reminder. It’s through collective curiosity, courage, and alignment that we move forward, not just as scientists or thinkers but as a species. Thank you for framing this so clearly.

[@shawns0762]

@@Leyrann I studied physics for my own knowledge not for a career so I don't have a PhD. I realized dilation explains dark matter before those galaxies were discovered. All galaxies with low mass centers have normal rotation rates. More will be discovered soon. A graph illustrates the phenomenon of dilation. It has velocity from stationary to the speed of light on the horizontal line and dilation on the vertical. This shows its squared nature, it increases at an exponential rate the closer you get to the speed of light. The best way to understand it is to imagine a spaceship traveling at a constant acceleration rate. When the ship reaches 50% light speed, as viewed from an Earthbound observer with a magically powerful telescope, it would appear normal because as the graph shows nothing has changed at that point. When the ship reaches 75% light speed it would appear fuzzy because as the graph shows relativistic effects would be noticeable at that point. When the ship reaches 99% light speed it would not be visible because every aspect of its existence would be smeared through spacetime relative to an Earthbound observer. This is the state of mass in our galactic center. It's not just there, it's everywhere.

So, I am fine with scientists researching and learning about the physical principles that makes up existence.

What if it is masked by a field that might be turned off locally? Then the engineers get to work, and…..

I am an electrical engineer (applied electromagnetics) working in corporate applied research and new product development. In the corporate applied research world that I experienced, the "big question" used to evaluate the benefit of working/spending money on a topic was ""So what?" While this experiencve may not apply to fundamental or basic research at university or government labs, this question was used to focus our corporate research dollars to provid bigger "bang for the buck" in improvement of existing products/processes or on technologies that could radically disrupt existing products/technologies. I think there is a general understanding in research that we can never know all of the potential upsides to new developments in a technology or science, and that the "killer app" for a new technology is not often the answer to the "So what?" question that drove the research in the first place. As a tool for evaluating what new research to sponsor, it can be a valuable guide. Having said all this, sometimes intellectual curiosity should be allowed to be our muse for discovery, I just wouldn't fund it with 50% of my research budget.

Electricity could obviously be used for neon lighting when the near-vacuum gaseous vapor atop a column of mercury is ionized. Volta's frog legs stimulated by bimetallic junction's electricity showed that electromotive force to generate motion was possible. The bipolar-junction transistor was invented because electromechanical relays were unreliable, bulky, and required much electricity to work. The cat's-whisker-crystal radio has already been working for decades before the post-WWII peace allowed the leisure to try to understand the physics of the semiconductor radar rectifying tubes used during the war. The Bell Telephone Laboratories had a real business problem to solve because the electromechanical relays could get stuck or stay open. They are very difficult to be isolated and replaced. The telephone money was coming in so the reliability of conversation had to be achieved. People usually do have an inkling of what the applications may be.

Not a physicist, with my mathematical skills I’m barely an engineer (struggled with multi variable calc)… but such topics are interesting to learn about as I drive to/from work… That said: I have a question I’m mildly curious about. For the sake of this comment section it’s rhetorical, maybe it’s a proposed question for minds more adept than my own to go explore…. Or perhaps it’s not a novel thought and then y’all can just move on: If quantum effects break down under observation, what other events cause quantum effects to break down: is there a way to prove the effects are breaking down without attempting to observe them? I would think if minds much more keen than my own could find other events, more knowledge can be gained in the absence of the quantum effect: having a more significant list of criteria which cause the effect to break down means more opportunity to study why it breaks down, and if we learn about the “why”, we may learn more about the “why not”. This may be a naive question, but then again, maybe not. Thanks for reading.

Back in the 90s, when I was a teen getting deeply into computers, I had a thought: If you went back in time to like 1850 and you told someone 'hey, one day we are going to have machines that can do billions of mathematical operations per second' and asked them what impact they thought such machines might have, there would be no chance, whatsoever, that they could have imagined how radically computers have altered every single aspect of human civilization. And then I wondered what development like that might be likely in our own future. Something which at its heart seems like it'd be simple, but which bears world-changing fruit. What I came up with was that a fundamental understanding of the nature of complexity would revolutionize everything. The ability to design, intentionally, very simple systems of dynamically interacting parts which can give rise to predictable, controllable, engineered large-scale change. While mathematicians delude themselves by saying mathematics is the language of the universe, you ask them to figure out nonlinear dynamical systems of a dozen parts interacting and they immediately fall apart. Physics obsesses over vacuums and isolated systems, and doesn't much want to even nail down where 'temperature' comes from and is comfortable with merely observing that a 'large enough' collection exhibits it with predictable dynamics determined by observation rather than through generalizable principles that might enable us to design our own 'large enough' collections of interacting particles to give rise to something different from, but sharing traits with, temperature with its scale-free phase change diagrams and whatnot. THAT would be new physics. THAT would change the world in ways too monumental for us to be capable of imagining it.

[@ardalla535]

Interesting to note that completely empty space has no temperature. It's not zero K. It doesn't exist at all.

I would classify 'a fundamental understanding of the nature of complexity' under the P = NP discussion. I may be biased based on my background (Industrial Engineering/Operations Research/Computer Science), but that question has very far-reaching practical implications at every point in life. It doesn't quite fit the criteria you're looking for, though, as it is very understandable (at least to some of us) how revolutionary that would be. Unfortunately for the topic, I think the nature of complexity is impenetrable to rational (not just scientific) inquiry.

But does that answer offer practical application such as fast interstellar travel, or efficient access to energy conversion or greater confidence in the physics that we use already such as landing devices on the moon the right way up. > We have a lot of competing theories so for me it would be practical to bin everything that doesn't work and only keep the "correct" principles.

I know it's a poor analogy because photons don't fall into a shadow like particles of mass fall into a gravity well. But I still can't help but feel that gravity is the "lack" of something (Like the lack of space-time or some inverse concept of the vacuum.) > 7:35 For me Quantum is and always will appear to be fuzzy, not because of our measurement but because it is naturally fuzzy. If we imagine the now moment as a wave (either half or full) so it is a physical period rather than a time period as we typically think of it; I can imagine the universe being manipulated and formed (hidden) near the front of the wave, and classical reality (what we and the universe "seams" to experience) emerging near the back of the wave. The back of the wave being local and the front being non-local as well. So we have a kind of perpetually cycling wave moment from back to the front. We don't have direct access to the front of the wave (quantum) and can only ever realize it at the back of the wave. In some sense this allows for some non-local leeway "across" the wave so to speak. (I was attempting a thought experiment to visualize if I/we could "push" something into the non-local part of the wave for FTL information transfer.) > > I know I often say this, but take it as an alternative perspective/thought rather than any concept of a solution. . Make everything mathematically blurry/fuzzy. No discrete finite points, no '=', only approximate. So, everything that approaches a discrete mathematical boundary transitions through rather than ever reaching that point. . You can imagine a line of width passing over a line of width rather than an invisible point passing over an invisible point. (Is there such a thing as a physical non existent point?) . Everything is a transition, so the cat isn't dead and alive, it becomes not fully dead or fully alive as it is in transition. I wonder if it would be possible to emulate the analog precision by using whole numbers with mechanical analog for the fractions (infinite float values).

[@NemisCassander]

@@axle.student So a couple of things. 1) If gravity is the lack of something, why does it increase with mass? (That is, the gravitational force increases with mass.) Given the macro equation (Newton's), if gravity is a lack of something, it's... free space? If it increases with mass and decreases with distance, then you could say it's a measure of crowdedness. On a weird tangent, I build discrete pedestrian flow models, and if you don't get the parameters right, you often get this huge mass of colliding pedestrians, none of whom can go anywhere. It's sort of like gravity. 2) While the 'fuzzy' perspective should not be lost, neither should the crisp delineation of the = sign. It's the difference between describing something and defining something. A definition, as the term implies, is definite. A description can be quite loose. The danger in moving to a purely descriptive approach is the loss of certainty.

[@axle.student]

@@NemisCassander On point 1. I know its a difficult thought, but it is along the lines of inverting a vacuum. So false vacuums, +/- vacuums etc. So it is a concept of "inverted" when I say the "Lack off" Like the lack of light in a shadow. So you can think of it like a lower pressure region (lake of) in space-time, where pressure pushes stuff together, rather than a force that pulls stuff together. > This is a point (2) that is strong on my mind and may ultimately have no easy solution if there is a solution at all. Analog (mechanical, fluid systems) have no '=' operator. There is no such thing as '=' in analog. It is always a comparator between a lower and upper limit with a fuzzy approximation "somewhere" in between. Nature appears fundamentally analog (like). To attempt to describe that in a static discrete way breaks the very principle of an analog system and it no long behaves as an analog system. . It is possible that we are "breaking" and loosing the fundamental property of the universe by forcing a discrete digital description of it. You can't correctly describe an analog system with digital. This problem shows up everywhere in both relativity and Quantum. . In some sense it is like attempting to illustrate motion by taking a finite photographic snapshot of it. You will never find the property of motion in that static image. Placing a series of static images in a row still does not solve the problem, even if it tricks the human mind into thinking that it has. . The description of the above problem becomes extremely complex, so I will stop there :)

[@NemisCassander]

@@axle.student Perhaps what we need to look for is not the concept of equality, but the concept of equilibrium, as those do appear in analog systems (e.g., chemical reactions). Having said that, I'm not sure I agree with the idea that you propose that equality cannot exist in analog systems. If that is true, then the statement is an attack on reason itself, as mathematics cannot prove anything without equality. And once you start attacking reason, quite literally all thought collapses, as Chesterton so eloquently argued. Put a bit more simply, if you ever propound a theory that would invalidate reason, that theory must either be wrong or meaningless, as reason had to be used to develop that theory.

[@axle.student]

​@@NemisCassander "Perhaps what we need to look for is not the concept of equality, but the concept of equilibrium," This is in the correct direction in my view. . Analog systems, beyond a singular object, exist in a state of comparison. That's why we talk about "comparators" in analog systems, but it has no "=", only ≈. A small even infinitesimal amount of uncertainty always remains. This does not mean we can't pull close approximations of discrete digital values from it (logic). This is exactly how a modern digital computer function. > So yes, there are states of equilibrium, but they are a kind of fuzzy balance. Analog is dynamic, always in constant flux and never static. But like passing wave crests we can count the frequency with some degree of certainty even if we can't measure the exact peak of the wave crest. (Exactly how we convert the underlying analog system to emulate a digital representation in a modern computer.) . I feel that it is this fuzziness or uncertainty in that measurement that gives rise to a non deterministic universe where complexity and stability can emerge from the subtle noise (fuzziness) in the system. Like being able to count the fuzzy crests of the waves we can also have an emergent form of determinism (certainty), but the infinitesimal uncertainty always remains. > Make no mistake though, it is a difficult dilemma for us humans to deal with if correct. It breaks most of our math, and goes against some parts of our logical thinking. I have no current solution for that. Maybe Wolfram will find it in the hyper-geometry, but I am not confident. > P.S.

Well yesterday I was watching interview with Prof. M. Czachor. He is working on new arithmetics for physics. He concluded that time flow in large scale (long period) should be calculated differently. It's something like calculation of speeds near light speed in Einstein relativity theory. He had recalculated physical formulas which suggests that there is dark matter and it seems that if you take into account his new arithmetics everything fits without those dark matter and dark energy. He compared serching dark matter and energy to serching of ether. One of his works: "Non-Newtonian Mathematics Instead of Non-Newtonian Physics: Dark Matter and Dark Energy from a Mismatch of Arithmetics" and "Cosmic-Time Quantum Mechanics and the Passage-of-Time Problem".

*"Many theories that were once deemed "fantastic propositions" became paradigmatic. The big bang, quantum properties, black holes were all ridiculed at some point."* ... And rightfully so. Big Bang is a perfect example. Whereas everything after BB's singularity is logically conceivable, the singularity is not. Even Big Bang proponents accept that the singularity part is problematic and cannot be logically reconciled. However, "Multiverse" posits an "infinite origin" (no beginning) which is logically inconceivable; therefore, everything that follows in the Multiverse hypotheses is moot. To prove my point, the universe is estimated to be 14 billion years old. So, if I asked you what the midpoint is for the universe (with today being the most recent time) you would answer with, _"Seven billion years ago."_ However, if I asked you what the midpoint of the Multiverse is (with today being the most recent time) you would not be able to give me an answer. You can't because any proposition that's based on "infinite origin" cannot be logically reconciled within the human mind, ... yet we still waste so much time discussing it like it's something that might be "real."

Our efforts to make better batteries or more durable glass are all done by trying things at random and testing to see if we have improved anything. We have spent decades in trial and error, not by actual design from knowledge on both of these. The same goes for electronics and biology. If I ask what is the optimum topology for an antenna that has certain characteristics, we don't know. We can guess at something and simulate it, but we can't simply design it without randomly trying things. In electronics, we try different gate structures, different semiconductor materials, different dielectrics, different doping, adding strains, etc., but it's all by trial and error, not by design.

Summary of my model. Here are the key components of all my physics posts: Photons are eternal and outside of time and distance. The singularity of photons began the Big Bang. Photons created mass through pair conversion of electron positron pairs in the Big Bang. These electrons and positrons made the elementary particles which in turn made the atoms. Protons are made of two positrons and one electron. Neutrons are made of one proton and one electron. Protons, could mostly be created in the immediate era after the Big Bang when positrons were plentiful Neutrons are unstable protons and decay in 10 minutes. The proton neutron bond in the nucleus, kept neutrons from decay and was key to building all elements. Neutrons and hydrogen atoms may be the same thing, but with different electron placements. The key to atoms stability may be the deuterium nucleus or deuteron that help binds one proton to one neutron. The missing anti matter is in protons and neutrons. Photons, electrons, and positrons, may be different versions of the same thing. Both electrons and positrons may move in a helix motion. Charge may be opposite helix movements. The horizon problem may have another possible solution. Virtual particles may be a key part of quantum leaps. Virtual particles may power beta plus decay. The mass of the universe comes from photons converting to electron positron pairs in pair conversion. The energy of the universe comes from electrons and positrons annihilating and converting to photons. The universe is 5% charged matter from Electrons and positrons, and 95% neutral force from Photons The universe is 5% electromagnetic force and 95% Dark energy or Antigravity. Dark matter is not gravity from invisible baryons pulling, but antigravity pushing from empty space. Dark matter and Dark Energy are both anti gravity pushing from empty space. The cosmological redshift supports this. The force from the Big Bang singularity was photons / dark energy / dark matter /anti gravity . They are the same. The force caused by acceleration is anti gravity, not gravity. Galileo and Newton's discoveries work for either gravity or in reverse for antigravity. Big Bang may be energy in, not expansion out. Time has speed limits up to the speed of light. The universe is open ended and will continue to expand. There may be two universes. This one and one of photons.

Newton's gravitational attraction, F=H(m1m2)/R2 says motion comes from mass and yet no matter what m2 is F (motion) is always the same. So, cross off gravitational attraction, the big bang, dark matter, expanding universe and you are left with the Acceleration question. Where does Acceleration come from. Religion says a creator god set the universe in motion. F=ma says Acceleration comes from Acceleration in an infinite universe. By definition, an infinite universe is one that is undefined, unbounded. Which is a mathematical impossibility. As a physisist, you have to either accept the notion of a creator god or the mathematically impossible. Or you could create a totally fictitious universe to dwell in. The majority choose the later. The alternative has already been explained by Religion.

It is very surprising how long its been since any new Physics has been discovered...

Try Plasma Cosmology, the only self-contained physical theory of the universe (the science is still called "physics", after all). Your comment is exactly right as applied to academe.

Thanks for getting back to physics. I'm sorry for the trouble you went through but to be honest I was falling off as a viewer for the brief time when it was just about scientists arguing with each other. There's way too much of that everywhere else so I hated to see you get pulled into that world of arguing and resentment. I treasure channels that are just about the topic as it is a welcome escape from way too much constant conflict we all encounter. I hope that's not insensitive of me. I just wanted to give my honest feedback as a loyal viewer, and tell you that we really appreciate and enjoy what you do. Thank you for that. We love it.

I am surprised the most practical used of Dark matter is not mentioned...employment!!!!!

its so hard to imagine what one can not touch or reach.

[@williamschlosser]

Try a theory based on proven EM forces, that make your appliances work: Plasma Cosmology.

Looking for an honest woman. 😂

Oxymoron? 😂

Advanced Physics is often enabled by Advanced Engineering. Currently, we have reached the limit of possible experimentations enabled by engineering. The hypothesis that cannot be verified in experiments does not meet the criteria of the Scientific Method. Without the scientific method, humans usually go into circle jerks.
