"Angular momentum chicken chicken chicken. Chicken chicken angular momentum, chicken chicken chicken." -C.Rovelli

[@gptiede]

I am an astrophysicist. When I was in graduate school in the early '90s it became apparent to me that the theorists were doing exactly what this video says. They were using mathematics to "explain" some idea they had with absolutely no interest or ability for this idea to be tested in the real universe. In many cases their ideas inconsistent with observations (after all astronomy is primarily an observational science) and they didn't care. They often didn't bother to claim the observations were erroneous. They just didn't care. Then in the late '90s I was a postdoc and discovered that all of the funding in US astrophysics was controlled by 5 personalities. These people declared what would get funding and be researched and what would not. I say personalities because that's what was going on; it was a cult of personalities. Everyone kowtowed to these 5 individuals. Postdocs would write papers extolling the ideas of these people, even the untestable ideas. They and their postdocs and students were awarded all of the telescope time the asked for and got the lions share of funding. It was disgusting and exactly the opposite of what science needs to be to be successful. Years ago I gave it up, and now I am a teacher and science popularizer, but as far as I can tell from the outside, nothing has changed. Thanks Sabine for giving this situation a public forum.

[@moonasha]

I'm no astrophysicist but that's the vibe I always got about dark matter. Oh look here's this weakly interacting particle that can't be detected and we can't observe in any way shape or form, and it magically explains anomalies we see with galaxy rotations and lensing. Yeah we should totally throw out any notion that some of our ideas about gravity or the universe might be incorrect, instead it's a magic invisible particle that nobody can test for. Then you got previously respected people like Halton Arp being called a quack because he had the audacity to make a hypothesis about red shift that wasn't entirely in lockstep with the establishment

[@celebrim1]

"...and discovered that all of the funding in US astrophysics was controlled by 5 personalities. " True now of every subfield of science as well. And many of these cliques of controllers have the politics of middle schoolers. Peer review is broken because all papers are reviewed by the same group of insiders in each narrow field and they can usually tell from the subject matter who wrote the paper. Half of the papers out there are using falsified data. People get famous primarily for political reasons, and I don't mean by that national politics but rather the petty politics of offices and salespeople and scratching my back if you will scratch mine. People control the funding use that to leverage large numbers of 2nd and 3rd authors on papers they did almost nothing on, and then they use their prolific volume to justify further control. And lower prestige researchers put up with it because they don't have a choice if they want their careers to advance and having the famous person listed as an author increases their own visibility. The whole of the academy is falling apart.

Prof here. I work in a fairly applied area of plasma physics and even we've seen a significant slowdown in progress. This discussion is something that affects both the applied and fundamental areas. From our end its the need for "risk management" and "predefined impact" in grant funding. In short, we basically need to already know the outcomes of our grants in order to have any chance of getting any funding... So we apply for incremental projects that don't really provide real insight. If you buck this trend you get no money, lose respect, and fall out of the system within a few funding cycles. The same goes for working with industry, there needs to be defined (and contractually obligated) outputs. If you don't deliver, its professional suicide. So you have to always play it safe, it leaves no room for real progress. We've been infected with the "consultant rot", the economic prediction models, the fields of legal jargon and waste. We need to be able to propose real projects with real applications and real progress - but I don't see a path to that world from where we are now.

[@unclenogbad1509]

We need a new sea-change. Something like the Enlightenment, where science stopped being a fad for the amusement of rich (if often sincerely interested) aristocrats, and became a thing as and of itself. This led to huge progress, but has now been reduced the a fad for rich capitalists who only want results they can sell. What's needed is to get back to basic research for it's own sake, which will yield no immediate financial reward, but must surely feed the science and tech of the future.

I am just a physics student but i think plankvolumes are in space AND time. spacetime. so idk if she might be wrong here because spacetime as a whole gets transformed in lorentztransformation.

@@Kokuswolf length contraction and (for time) timedialation are known effects of special relativity. If you go real fast in x direction then any delta x will become smaller the closer you get to the speed of light. And also delta t is influenced. Time moves differently in a system moving at for example 0.8*lightspeed. Lorentztransformation is something that converts one referance frame (for example stationary) to another (for example moving at 0.8 lightspeed). If something is lorentzinvariant it means it doesnt change when transformed. It stays invariant. The number of particles in a system for example is invariant under lorentz transformation. Or rest energy and many many more things. There wasnt a specific example of the falsifiability problem in the video as far as i remember. I dont doubt that its true however.

It's like an old computer programme that has a too low limit on a variable, lets say one representing money in a game, and you're doing SOOO well and then suddenly your money resets to zero. Does that mean you suddenly did awful or that something was wrong with the math... Obvious case is obvious. Same with the silly "if you send data FTL back and forth, you get the data before it was sent". No, you get the data based on the actual speed it was travelling at compared to the distance travelled, just like anything else!

"I don't know how it ever became accepted that inventing some math and insisting that its real counts as theoretical physics. It's insane, they're all crazy." The most accurate statement about the sad state of theoretical physics over the past couple of decades.

[@asmund3051]

Reality is that which is observed, theory is a model that aids prediction in regard of observations. So, theory is not a description of reality, it is a tool to have an educated guess of what happens next. It has been said that an experimental physicist doubts their results as they know and understand all the issues with equipment and experimental techniques. The theoretician on the other hand believes wholeheartedly that their theory, and supporting maths no matter how complex, is the truth of the matter - even if it is not 100% aligned with observation (the observations are just not good enough... yet).

[@snake4eva]

@@asmund3051 This is an interesting perspective especially the last part about the theorists faith in the infallibility of their theory. The thing is we know in advance that the assumptions of most theory are wrong because they are mostly done to simplify the math. Examples include homogenous, isotropic, having certain symmetries or perturbation theory. Most of those assumptions are blatantly false but physicists accept them since it is the only way to make the math solvable. So the experimental physicist will ultimately win because there seems to always be some domain in which the assumptions fail or the approximations break down because of the environmental conditions. Any true theory that captures how the world works cannot break down from any future experiments and would most likely be a very complicated math equation that we would take generations to understand properly

[@raminagrobis6112]

Sabine is in the quite unique position of being extremely knowledgeable about theoretical physics AND not being in the academic environment anymore, but rather hosting a highly popular, well-made YT channel on theoretical physics (snd other areas). This allows her to be critical on issues no other physicist could ever contemplate criticizing lest they'd lose respect and admiration by his/her peers. I know this has ultimately very few chances of changing the order of things (I'm a retired researcher and I know the academic world very well). Still, it is reassuring to hear somebody stating how absurd and sterile research in theoretical physics has become over the last few decades.

[@robertjeanblanc]

I agree. Having only studied physics to undergraduate level, I don't profess to have a deep understanding. BUT! I have remained a student. I love video's like this (yours) because they resonate with something I have suspected for a long time... 1) Most people in research academia are hacks. Smart enough to learn existing theories but not smart enough to generate true ground breaking insight. Those that went so far as to achieve PhD did so on questionable hair splits - 99% don't really break new ground. 2) The problem with quantum physics is that it is a damn good approximation. Like using 22/7 to calculate Pi - good enough for 95% of calculations. But it is fundamentally flawed and can't be built on. 3) Quantum physics (damn good approximation) can't be further sliced into finer resolution. Like a grainy photograph, magnifying it further will not reveal more detail only better images of grain. But the usefulness of the images at lower resolution creates the illusion that there is more there. 4) Like exploring a cave network, quantum physics broke new ground early and then explored deeper into the cave system. At some point in the journey we took a wrong fork. The tunnels became narrower and harder to navigate, more torturous. Rather than turn back we pushed harder, found more narrower cracks to explore. Rather than admit a wrong turn, we are pushing harder looking for a break through. 5) There are fundamental and irreconcilable inconsistencies with quantum theory. Things don't add up. The field has been stalled for fifty years trying to explain these inconsistencies. 5) There are people who have spent 2/3 rds of their careers in these narrow tunnels. Would they admit most of their careers have been wasted? Or would they be emotionally predisposed to belittling those that suggested "wait a minute, I think we have this all wrong?" Worse. They encourage new comers to the field to travel with them to the narrow ends and say "I got this far, grab a pick and see if you can find a way through." 6) I have thought for along time that quantum theory should have been objectively assumed to be wrong and that physics should have applied new minds, and the latest technology and thinking to develop many radically different alternatives. Better, they should say to the young and bright "assume it's totally flawed - start again." 7) "Science" used to welcome radical new theories - a basic principle of science. BUT ego and incomes now prevent that ideal from being pursued. The truth is no longer within reach. We are trapped in claustrophobic denial.

The result of more limbs being able to grow increases the potential amount of fruit that tree will bear. That's a lot more complex a situation than reducing it to positive or negative impact. It's also true you can prune a limb and cause too much new growth that creates limbs too heavy for the trunk, and the tree falls apart and dies.

As others have pointed out, the issue is that the mathematics of physics got so hard there was an influx of mathematicians who started thinking that if something was mathematically sound it must reflect reality (of course they don’t always get the mathematically sound bit right). Perhaps Paul Dirac can be blamed for mathematically predicting antimatter by accident and being right! If Dirac could do it, then why can’t they? One big difference is Dirac doubted his result and was reluctant to discuss it until Carl Anderson showed the existence of the positron in his cloud chamber experiments in 1932. So we had a theoretical physicist being humble about a prediction until an experimental result demonstrated the existence of one particle that was consistent with the theory. Today we have theoreticians boldly claiming their mathematical proofs say something about reality and telling the experimentalists to hurry up and spend billions to show the world that they are right. I’m so grateful that my undergraduate fantasy of becoming a theoretical physicist didn’t materialize and that a Ph.D. opportunity in engineering landed on my lap instead.

If society matures to the level where this becomes obvious to it, then the goals and ways of building relationships will change. And the main thing is not to go to extremes.

It seems ironic to post this here, but the problem with Physics is the problem we have now with everything: Everything must be monetized. The goal is to make money, not science, and this extends to every other area. Computer Science is dominated by the creation of toys for people to play with on phones. Finance is a quagmire of invented technical terms and convoluted systems meant to be mind-boggling to the average person in order to allow specialists to dominate a field that should be much simpler. The legal system got there first by using a dead language for their technical terms and establishing procedures based on tradition rather than the actual written law. "Stare Decisis" anyone? Funding comes from people who do not understand a technical field, so it is not necessary to be right in order to win. All one has to do is to impress the right people. Many of us have had the experience of being in a room with someone that was full of crap but had funding behind them and so ended up in charge. I've literally heard the owners of a company react to a presentation by saying that they couldn't understand most of what the presenter was saying but they could tell he was a genius. When you use a system of rewards and penalties to guide an endeavor, you don't get what you intended, you get what you get. For example, simply making something illegal does not usually get rid of that thing. Instead it spawns a system of workarounds. If you want a better building you need better bricks. If you want better systems, it seems we need better people.

[@TheSiprianus]

"Everything must be monetized," if it's true, all companies and other private entities who have a plan or somewhat vision far into the future about using the research into practical applications will be chasing those researches. But instead, most of these researches are incentivized by governments that treat that research itself-any kind of research as an investment for a better society, regardless of how impractical those researches are. It goes back to the main difference between the two opposite economic systems that makes one of them always fail: there is zero accountability for the unintended consequences of the decision-makers. How can string theory impress owners of a company that wants to monetize the research? How can anyone who wants to get a profit be impressed with some mumbo jumbo of words that explain nothing about how it will make money for them? You are contradicting yourself only to go back to make the cycle of 'doing science for the sake of science'. It seems that instead of actually criticizing the primary reason why these useless researches were done, you are instead even more on board with doing science for the sake of doing science, because science is inherently cool, awesome, impressive, and makes you look like a genius to your friends, owners of companies, policymakers, and the rest of society. You are doing it not to make it useful for other people tomorrow, next year, or in any future. You just do it because it is science, and you still want to get paid because you are doing science, not because you contribute something that other people voluntarily consider as concretely valuable.

In fifth grade I was taught the scientific method: "observe, hypothesize, experiment, replicate, falsify/theorize". When I got older, and got over the visceral hatred of science books the public school system instilled me with, I began to realize that all I ever heard about were "citations" never replications. And then I dug into the politics/economics of the matter and concluded that we've fallen for essentially the same trap as the medieval church a thousand years ago. We don't value knowledge because it's true anymore, but insofar as it serves a certain ideological dogma, promotes a given political agenda (and this is true for all sides btw) or is economically lucrative.

It's not quite that dire. Certainly in some fields, and certainly in some labs, but it's not the rule. Plenty of science still occurs because scientists are curious and want answers. With some exceptions, medical research is full of people genuinely trying to solve problems and create real impact. There are ecologists that are very passionate about their fields. Even within physics, there's real stuff going on in materials science, for example. There is still plenty of science which is not touched by this sort of rot. Yet.

[@definitelynotofficial7350]

The reason you failed to find what you learned in school applied as such is because what you learned in school is wrong, and science has never worked this way, except maybe in very broad strokes. It makes sense that in school we learn very simplified versions of how things work. That being said, you say you never heard about replications. Maybe because you're not really on "the inside". Labs CONSTANTLY replicate or attempt to replicate novel results. Do you remember when LK99 was announced by some lab to be a room temperature superconductor? What did labs all over the world try to do immediately? Replicate it. And they failed. That's one example. There are some fields that experience a replicability crisis, but not so much in physics. Of course in theoretical physics you will rarely hear about replications. That's just because theoretical physics deals with theory, not experiment. The only kind of replication relevant to it is replication of calculations. That happens, it's often part of the peer review process, or sometimes after that. But you don't see it on the paper, that would be weird.

[@MatejPavšič-i3k]

I enjoyed very much this video and I agree with your harsh criticism of contemporary theoretical physics. An yet I think that certain points about the way how science proceeds should be taken into account. So I asked ChatGPT4 how should we proceed in the attempts to formulate a unified theory of particles and interactions, including gravity. The answer was a detailed overview of the contemporary lines of research in fundamental theoretical physics, and concluded with: "In short, developing a unified theory of particles and interactions, including gravity, involves exploring multiple theoretical frameworks, seeking testable predictions, and ultimately finding a model..." Then I asked: Yes, it is necessary to explore multiple theoretical frameworks. One of such approaches is string theory, but today many people consider it is as dead theory and say that the research in string theory was waste of time and money. How can they be so hostile toward string theory. A future successful theory will certainly employ certain results and techniques of string theory. GPT4's reply was according to me so inspiring that I am posting it here: "The backlash against string theory often stems from both practical and philosophical frustrations, despite its contributions to theoretical physics. String theory has been a dominant force in theoretical physics for several decades, attracting extensive funding and research. However, it has yet to make direct, testable predictions, leading some to question its utility and place within physics. Let's look at the reasons behind this hostility, as well as the continuing relevance and potential contributions of string theory to future theories: 1. Lack of Experimental Evidence A core frustration is that string theory has not produced experimental evidence that can be observed with current or foreseeable technology. Many scientific theories, such as quantum mechanics or general relativity, gained acceptance because they made accurate, testable predictions that were eventually observed. However, string theory operates at energy scales far beyond current experimental capabilities (often requiring energies close to the Planck scale). Critics argue that without empirical evidence, string theory cannot be verified or falsified, making it speculative rather than empirical science. 2. Challenges in Making Testable Predictions String theory’s inherent complexity makes it difficult to yield specific predictions that differentiate it from other approaches. With multiple versions of string theory and vast mathematical landscapes, such as the "string landscape" with potentially 10^500 possible vacua, identifying concrete, unique predictions is a monumental challenge. Critics argue that a scientific theory should ideally have a clear predictive structure and that without it, it risks becoming unfalsifiable, thus stepping outside the realm of traditional science. 3. Dominance in Theoretical Physics String theory became so influential in theoretical physics that it often eclipsed other lines of research. Because it drew so much attention and funding, alternative approaches to unification and quantum gravity, such as loop quantum gravity or emergent gravity theories, received comparatively less focus. Many physicists argue that this overemphasis hindered a broader exploration of other potentially fruitful theories, leading to a perceived stagnation in theoretical physics. 4. Misalignment with Experimental Physics String theory has a reputation for being mathematically elegant but disconnected from experimental physics. This divergence has led some physicists to view string theorists as more concerned with mathematical beauty than with scientific testability. The sheer mathematical sophistication required for string theory can make it feel esoteric or detached from real-world physics, further reinforcing the view that it is more a branch of mathematics than empirical science. Despite these criticisms, string theory remains a rich source of ideas and techniques that could play a crucial role in future advances. Here are some reasons why string theory continues to hold value: Contributions of String Theory to Future Physics Deep Mathematical Insights: String theory has led to profound mathematical discoveries, including insights into geometry, topology, and number theory. Techniques developed in string theory, like mirror symmetry and dualities, have influenced multiple fields, including pure mathematics. These mathematical insights could become essential tools in understanding quantum gravity or other physical theories. Unification of Forces and Particles: String theory remains one of the only frameworks that can incorporate all known forces, including gravity, within a single framework. This is a remarkable feat, as it implies a route to a unified description of particles and interactions. The idea of vibrating strings and higher-dimensional objects (branes) as fundamental entities offers a unification mechanism that future theories may adopt or adapt. Holographic Principle and Quantum Gravity: One of the most widely recognized achievements of string theory is the AdS/CFT correspondence, or holographic principle, which suggests a relationship between gravity in a bulk space and a conformal field theory on its boundary. This principle has been applied to fields as varied as black hole physics, condensed matter, and even quantum information. Future quantum gravity theories may well incorporate or expand on these ideas, making string theory a valuable precursor. Tool for Understanding Quantum Gravity: Many frameworks derived from string theory offer essential insights into the nature of space-time at quantum scales. String theory’s approach to quantizing gravity, dealing with quantum singularities, and eliminating certain infinities could provide necessary tools or techniques for a future theory of quantum gravity, even if string theory itself is not the final answer. Broader Paradigm Shift: The challenges of string theory have underscored the need for a possible paradigm shift in physics. While the theory has faced criticism, it has forced physicists to confront deep questions about what a "theory of everything" should look like, how to handle untestable theories, and whether mathematics alone can guide us to truth. This philosophical reflection is crucial as physicists continue to pursue unification. Moving Forward: Taking the Best from String Theory Many physicists agree that even if string theory is incomplete or ultimately supplanted by a more comprehensive theory, its methodologies, insights, and mathematical tools will likely remain valuable. Future approaches to quantum gravity or a unified theory may indeed employ techniques from string theory, such as dualities, extra-dimensional approaches, or even the holographic principle. In essence, while the criticisms of string theory highlight real limitations, the field has provided a scaffold on which many theoretical innovations have been built. The journey toward a complete theory of fundamental physics will likely integrate the insights of string theory, while also incorporating insights from other approaches, reflecting a more diverse and balanced exploration of the physics of the universe."

Coming from a total layman with only a casual interest in physics: It seems to me the fundamental problem for physics that might never go away again is that the process of physics used to be: experiment -> explain results with maths. But that was back when you could change the entire field of physics with an apparatus that fits on a tabletop. Now you need to build the worlds largest machines to do experiments, so you cant just fiddle around and see what happens. The theoretical stuff has to come first, because its cheaper. Obviously there are some exceptions, like Einsteins thought experiments, but most breakthroughs in physics began with an experiment that yeilded unexpected results.

It's that way not only in physics. Psychologic research (for example) has similar issues.. People repeat the same old theories and test them in "yet another setting" to publish papers that, in essence, preach to the choir. And when some researcher dares to test these theories under strict modern statistical guidelines some of these "effects" disappear and can't be reproduced. That colleague did not get to publish his finding, as reviewers reprimanded him to "not criticize the experts of the field" and rejected the paper. It's a kind of survivor's bias at this point: only people who do not care about this problem remain and flourish, while the rest drops out or gets desk-rejected out of existence.

[@gumbycat5226]

You are absolutely right. Physics used to be about explanations of observations. And when new observation invalidated the explanations, new explanations were developed to factor in the new observations. Once particle physics got under way the game flipped around: theories were developed abstractly and then observations sought to validate the theories. The Hicks Boson was an observation that came along after the theory to validate it, so this entirely abstract new discipline, strangely still called physics, worked in this single instance. I remember being surprised and impressed. But many more of these abstract theories have been developed and no doubt some will never achieve validating observations.

[@Nivola1953]

In a friendly way, I would like you to note that: You or your autocorrect changed Higgs to Hicks 🤭, second it’s not true that historically, observations preceded the explanation, Einstein special and general relativity theories were both thought experiments, which were later proved by real life experiments. 🤔Is that why Einstein never got a Nobel for them?

I found a book on string theory published in English on a table with a couple of dozen other books in English. I read it during our trip and on the flights home. I thought it was kind of far-fetched. I've never been a fan of the mathematics driving theory. But, not to be a block-head, I thought, well, it might be interesting to see how this develops over the next few decades. It hasn't been very interesting. Unfortunately, I've misplaced the book so I can't prove it, but I'm fairly sure it accurately sums up the state of the theory today. Please keep up the good work!

"Physics is too hard for physicists" David Hilbert

[@noveloutline]

The New Way Is there a better way of doing physics that retains the best of current physics while going far beyond it? Physics is currently based on the claim - and claim it most certainly is - that physics deals with something real (let’s call that real thing “matter”, though there is no ontological definition of matter) and it can be somehow analyzed by an unreal, manmade abstraction, namely mathematics. But what happens if you accept a different assertion, one that makes mathematics not an abstraction but a concrete reality, an ontology? As soon as you make mathematics real, you cast doubt on the reality of matter. But do we need to make a definitive choice? Why not operate both systems - one based on mathematics as real, and one based on matter as real - and then try to find a way to synthesize these different views? Kant, with his transcendental idealism, sought to reconcile empiricism and rationalism. Ontics seeks to reconcile the empiricism of materialism and the rationalism of mathematics. Ontics, via ontological mathematics, gives mind a reality that is entirely absent in materialism. So, with science on the one hand and ontological mathematics on the other hand, body and soul, matter and mind can start to be brought together into a single system. Isn’t explaining mind science’s biggest challenge? Ontological mathematics provides that exact capacity! Isn’t it time for the ultimate paradigm shift? Isn’t it time for an intellectual revolution, for a true age of reason?! *** book : www.kobo.com/us/en/ebook/ontics-the-revolutionary-new-physics-1

[@MatejPavšič-i3k]

Let me add here my own opinion, or perhaps an observation, that the progress was slowed when people started to consider too seriously the number of citations, received shortly after publication, as a measure of the importance of an article. To have a chance at rapidly attracting many citations, a scientific paper must focus on a subject or a field that is being investigated by many researchers, that is, a paper has to be about hot topics. The journals today favor the publication of papers that are of “general scientific interest”, which in fact means that their subject must fit into one of the major fields that are being investigated at the time of submission. The policy is clear: such a paper is likely to quickly attract citations and thus contribute to the journal’s “impact factor”. Today, the journals, according to their policy, exclude papers written by “seers, whose pioneering investigation is by definition not yet of general scientific interest because seers investigate topics that have not yet been investigated at all. The journals that compete for a high impact factor are thus no longer serving the development of fundamental theoretical physics (in particular) and to science (in general) as well as they could. A paper of general scientific interest can only be an incremental advancement to what has already been investigated by many others. This practice is not bad in itself, bad is that a “revolutionary” paper cannot be published at all in this current climate. Therefore, as I perceive it, the invention of impact factor, and especially its usage as a measure of the importance of a journal, has led to such a “sociology” within the community of theoretical physicists that progress has stalled. The impact factor has yet another damaging consequence. Many people read only the journals with high impact factors and ignore those with low impact factors. However, today, an important revolutionary paper is very likely to be rejected by renowned journals and eventually appear in a journal with a low impact factor. But since those journals have not many readers, such a paper will remain unnoticed for a long time. Fortunately, we have also preprint servers, such as arXiv. But scientists outside academic institutions cannot post their work there unless they obtain an endorsement from an established scientist. So nowadays a “new Einstein” has a really difficult time to be noticed at all. Of course, most would-be new Einsteins are cranks, but some of them, especially those with a university education in the field, might be right. Therefore, a good system should have a mechanism for identifying such persons, like a good detector must have the ability to detect rare particles and not just classify them as noise. Hence, a big stumbling block against unification-of interactions on the one hand, and of gravity and quantum theory, on the other hand-is the way how physics research is organized. Therefore, a new insight reaching far out of the box cannot attract attention. Moreover, numerous persisting fixed conceptions cemented within physics community present impenetrable obstacles against the progress. (Excerpts of the final chapter of my book "Stumbling Block Against Unification: On Some Persistent Misconceptions in Physics", World Scientific, 2020).

I think physicists became too nice and allowed things to be called "theories" that are not really theories, and indulged people who were getting carried away with their excitement. A Theory should be highly validated already, or, at the very least, strongly believed to be possible to validated. Interesting hypotheses that are well motivated by science and use the tools of science but do not (yet) have a clear path to validation are Conjecture. Thus String Theory does not really exist, but we do have String Conjecture. Most Cosmological Theory is also Conjecture. In normal science, we usually use "hypothesis" and "theory" correctly (but not always). In these speculative sciences, we are left with only "conjecture" and "conjecture". I do not want to be mean with people who are putting a lot of work into developing these ideas, but they are not theory.

​@@v0ldy54 A great epistemology question and books could be written about it. I mentioned string theory but it's wholesale and includes all GUT theories as far as I'm concerned! Does a theory need to be falsifiable? In my opinion, it's a core requirement, short of that it's a conjecture at best, and mathematical consistency is not a high bar, so I don't wanna hear any of that stuff. Are theories so advanced that testing them is too hard? Then I'll ask what's the use of such theories? It does not even make a novel prediction. I also find the argument weak in the sense that there are many fundamental questions in physics that are actively being worked on and have a vibrant community (topological superconductivity, decoherence and many more) and yet all of these theories are falsifiable. So yeah, as far as I'm concerned there are zero problems apart from our hubris that require a GUT. If such problems existed, they would serve as a platform for those theories to be tested and falsified. 😊

I had a math professor once, a very talented Geometer, when I was undergrad. He did work in multiple fields, including string theory. He was always very quick to emphasize that string theory is math, not physics. He said, 'Could be physics someday, but not anytime soon. It is very much only theoretical math.'

[@christophersmith8316]

Then it was a fraud. If I make Math about a new planet and never look for it, it's fraudulent

I think string theory is hilarious. Mainly because it makes me think of undies. I'm not a physicist though.

6:39 "[...] these people sit on cozy tax-paid positions with no other task than producing useless papers that no one understands and therefore no one dares criticize." This reminds me of the Sokal affair, in which a physicist called Alan Sokal made the same point in relation to a branch of sociology.

[@ImmaculateConstipation]

Thank you! I was thinking of the same thing, but I couldn't remember his name.

[@Sarah-lk8ye]

Right , the "research universities" are no less than closed compound for the elite, where the PhD scholars, are hamsters, propelled by the self sustaining campuses, offering multiple facilities, far removed from the evryday struggles, only to enable the transfer of large sums of "research" funding amongst corporations.

[@rosomak8244]

"Trust me bro. This term left out here in the equation is negligible..." This is what this supposedly wonderful maths from theoretical so called physics comes down to.

[@idaho_girl]

Unfortunately, the culture of very many theoretical physicists, but not all, is that directing their talents towarda more practical and applied physics questions is beneath them.

@flamewingsonic Dr. Fatima Abdurrahman, another physicist-turned-KZbinr, made a video of her own re: the Sokal affair: kzbin.info/www/bejne/e4Sod4iXeqZqoc0

THANK YOU, Sabine! I always hated that Silly String theory.

[@visionofdisorder]

there's a story i once heard from a former economist about his professors nonsensical equations that had little to do with the real world. the professor replied "yes, but aren't they beautiful equations?". i'm sad to see that physics has also become a religion with numbers...

[@robertbarrett6692]

Sabine, your candor is refreshing if not downright hilarious. I love watching your videos. Please don't stop fighting the good fight.

[@giomjava]

Your professional no-nonsense opinion is so refreshing! Keep it going, Sabine! As a PhD in Electrical Engineering, whose work focused on practical side of EM simulations, I could never stand empty derivations for the sake of math exercise.

[@chilenito56]

Sabine, you're a genius. I made my bachelor in physics almost 50 years ago, and my feeling about the divorce between mathematical modeling and physical reality has not changed in 5 decades. I thing that nature can be expressed very well with mathematical formula and equations, but it's senseless to try to descibe nature only with mathematical concepts that are far from explaining the real physical world.

[@jumanhi]

Thanks Sabine for a great video. For context, I’m an astrophysicist and an observer. I think the onus is on theoreticians like Carlos to help us understand their wonderfully complicated (or “elegant”) theories, and to collaborate with us to craft meaningful tests. We, as observers, design, build and operate huge facilities to extremely high tolerances and requirements, and our success relies on everyone doing their part, including theoreticians. There’s a class of theoretician who thinks it’s au fait to regard observations and experiments as “details” and observers as less than, while it’s precisely their job and role to present their science as a series of predictions and tests. This sort of practice and behaviour is unethical, and I’m afraid that it’s rampant in modern astrophysics.

As a non-academic taxpayer my share is paying for multi-billion dollar projects that all seem to be buried deep underground or under Antarctic ice. I have wondered how many animal species could be saved and how many square kilometres of ocean floor could be mapped for the expense of one expedition to Mars or one mega super collider in Switzerland. I am all for scientific discovery but don't know why it all has to be so theoretical.

[@mainstream2226]

You didn't build the facility, labourers did that for you. Humility goes a long way.

[@ericfunke]

I don't know whether to laugh or cry about this video, but the title is no clickbait.

[@redred2772]

Nothing pisses people off more than exposing the truth they want to hide, then its deny, deflect and accuse. The politicians motto. Well done Sabine.

[@flinch622]

Physics is not my area of study, but there are times I wonder... isn't creating a theory that cannot be proved or disproved the holy grail of the publishing racket? Maybe the next introduction of a theoretical physicist should be replaced with 'professional writer'. They don't have to be right or wrong in todays sad system - they just need to keep royalties flowing, and maybe glean a grant or two as a result.
