Correction to what I say at 14:22 -- The KATRIN experiment does not look for neutrinoless double beta decay, it's trying to measure absolute neutrino masses. There are several other experiments looking for neutrinoless double beta decay. Sorry about that mixup!
Interesting video, thanks! I have two things to point out: 1) Experimental particle physics doesn't just consist of high energy collider physics. Many other, smaller experiments exist and deserve funding IMO. I'm sure Sabine is aware, I was just missing the broader perspective in the video. 2) KATRIN measures the absolute neutrino mass (effective mass of the electron antineutrino). Neutrinoless double beta decay is searched at other experiments. E.g. GERDA, KamLAND-Zen, and in the near future LEGEND.
@@FrankWinchester I can't (and won't!) answer for Sabine, but me? I'd make sure every human child had decent educational, food, and health provisions. A very great deal of good, including good science, would be the result. Not to mention happier kids, worth their weight in gold.
LOL the heat death of the universe gag got me. That was actually very very funny. I now remember her doing something like that in a previous video, too. Well done!
...and much like forces of nature, her flood of logic is at times, over intellectually small minded heads; flat earthers and climate deniers come to mind at first...
WHat about all those socks that disappaer from the washing machines? Happens everythere, all over the planet. No trace. Socks never shows up radomly, only disappear. It also seems physically impossible that two socks from the same pair disappear at the same time; if two socks are missing at the same time, they are _always_ from two dirrefent paris. No exceptions. We need to build a lot of big and expencive machines to fighure this out. The theorists have no answers even, so experiments is the only way forward.
I want to thank you for asking the tough questions Sabine, and for pointing out the inconvenient truths. You do this in all of your videos, and it is not an easy thing to do. It takes real courage. But in doing so, you are helping me, and countless others like me, learn the importance of critical thinking. Not just in physics, but in all areas of inquiry. I am always learning from you Sabine, and for that I am truly grateful. 🙏
@repentandbelieveinJesusChrist1 not sure how that is supposed to relate to OPs comment. But anyhow, no thanks, one more reason better not doing any "repenting" to that ominous "he who" - am not particularly interested in becoming a zombie like this J character.
I may be weird but I think this is the not only the best physics channel on UA-cam but also the funniest. Sabine talks about science in a way I can understand and her jokes make me laugh out loud. Who can make physics funny? Now you know.
she is bad, she work for elite, she lied way to much, she was lying also for earth and many more things, for me it takes 2 sec to understand faces, she work for elite, lie as hell, manipulation work,, nothing more, think about this, she knows nothing but anything she talk about is that what she read before make a video.. we call email work, because she is not talking as she know things, she talk only on the way the boss want her to talk
Not the best. Not even close to the funniest. Best among all is russian channel "Ali". Something truly OUTSTANDING. Best in English is "PBS Space Time". Not to be rude, but this chanel is stupid and toxic in some places. I can't remember the name of another russian granma making just the same as Sabine without any hypocrisy and with a ton of humor and deliverance, while in Sabine's field the good'ol Neil Tyson handles all this much better.
That's what irks me about Sabine's dismissiveness here. She doesn't suggest any criteria for when we _should_ build a new collider, much less lay out a path for getting there without the incremental progress of building better colliders.
I took an interest in mond in school and one of the reasons that I kind of got burnt out was because that alienated me from everybody. And I didn't have the social wherewithal to know that that was happening until pretty late into the game. I had a couple professors I think we're trying to be supportive essentially, but I would have needed a lot of help knowing how to map out what I should do after my masters and do the right things before i finished, and I was too introverted and uncomfortable to force the issue, so eventually I ran myself into a corner, covid happened, and i dropped out.
damn this is a shame. Scientists really seem to enjoy being able to be patronizing or demeaning to people who investigate ideas that they don't think are worth it. I'm sorry you had that experience, there are a lot of respectable people who think MOND is a valid area of research. I hope you get back into physics, which university were you attending?
This social alienation is seen not only in physics. Pretty harmful for science and I'm not really sure on how to deal with it, except for swimming with the masses ... which is kind of pointless, if one wants to find out *new* things.
Huge shame. Hindsight is 20/20, but it might have been easier if you were studying under physicists who currently research MOND. I didn't do any research like that before I picked a school, either, it was all practical concerns for me. What I have to tell you is that if you retain any interest in physics, if this experience has not sucked all of the joy out of it, you should get back in the game *right now.* Trust me when I tell you that the longer you wait, the harder it will be. 3 years is not too long, not by a long shot. You're probably not even 30. You're nearing or at your intellectual peak. If you don't use this gift while you have it, you will regret it forever.
I'm very sorry to hear that. These things really shouldn't happen, but I know from personal experience that it can be difficult to find a supervisor who shares your interests and if you don't find one, things get very difficult.
Hi, try super-fluid dark matter,(condensed matter physics) if i understand acording to Sabine its great chances to explain dark-matter. ....all the best.
Anyone who has raised little children can tell you, this is a behavior deeply ingrained in our species; telling semi-logical stories to justify getting a new toy.
It’s like my dog. When he needs to go outside, he rings a bell we put on the door with his paw. He doesn’t understand what a door or a bell is…he doesn’t know the mechanisms of why a bell rings…but he knows that if he does this certain action, we let him outside. Now imagine you’re a physicist. You’ve been working in theory and simulations your whole career. You don’t know if you’re correct, you don’t know if the things that are being proposed in a new theory are correct or even possible, but you know that you need to work on them to get money. You know that coming up with stuff, regardless of validity even from a speculative standpoint, gets you funding. So they just keep plugging away. One must imagine a physicist happy…
I don't think it is snark, I think she is on the 'spectrum'. She has zero filter relating to people's emotions or feelings. I don't think she is snarky, just 100% cold, hard facts. She just as easily points out when she herself has made mistakes recently. She kinda reminds me of Spock. But that is just my speculation.
@@aquafyre- You can't do hyphens like that or it does a -strikethru- I think you need --double-- or a - space - EDIT. Ok, double don't work, but a space did.
As I oscillate between watching “Launch Pad Astronomy” videos and Sabine’s videos, my brain oscillates between “Oh,.. I think I’m beginning to understand” and “Way above my head, but at least I have a better chance of BS-ing my way through at the next cocktail party”.
The Newton Constant G also Oscillates as it is slowly decreasing as we cycle through to a different part of the Milky Way Orion Arm! Newton's "G" is dropping because Ambient EM Field Density in Vacuum is Dropping! SO THE MOON IS MOVING AWAY FROM THE EARTH AND THE EARTH IS ALSO MOVING AWAY FROM THE SUN FOR THE SAME REASON! The Constants cycle back every 130,000 - 200,000 and is the major force function of LARGE GLACIER ICE AGES! We are due for one in 10,000-50,000 years! ua-cam.com/video/Ygq-DK1p17E/v-deo.html
Wish they would do a collider in space using planets and the Sun. After setting up shop on the moon, let's build a collider to shoot stuff towards the Sun, using it's gravity to slingshot it back to us on the Moon over n over till we reach darn near "C" hopefully 0.999932% the speed of light. Then,. we will need a bigger one that utilizes Black Holes and Neutron Stars... Ever consider doing a piece on Long-Vax / Long-Vaxer ??? Sure, there are plenty of other channels doing pieces on the vaccine, Covid, and Long-Covid. You should do one on us Long-Vaxers. I will be your resource for accurate data on my 3+ year ongoing battle with Long-Vax. Yes - I got Long-Covid from the Pfizer Covid Vaccine. Shortly after getting the Pfizer Covid Vaccine I had been ambulanced to the E/R. My blood was starting to clot - Everywhere and my Heart couldn't keep up. 20bpm was my pulse when admitted to the E/R. I was that doctor's first Post-Vaccine Disorder. aka: Long Covid He went pale when he realized I was dieing right in front of him. And that was just the beginning... 3+ years and 5 Ambulance trips to the E/R, and 9 Doctors later, I still have Long-Vax. Most haven't heard of Long-Vax so I just say Long Covid because the symptoms are the same. Hell, some of my doctors initially refused to treat me since I had NEVER tested positive for Covid while in the E/R I had Long-Vax / Post-Vaccine Disorder / Long-Covid for 6 months before testing positive for Covid. Some of my doctors even refused to treat me because I didn't test positive for Covid!!! Im now seen by 9 different doctors, yet still have Long-Vax and sleep 16-20 hours a day. The fatigue that comes with Long-Vax is amazing... May God help us . . .
Please do a video on us Long-Vaxers ! ! ! (Those of us who contracted Long-Covid from the Vaccine) I have all the medical records and Covid tests to validate my story...
The funding part regarding colliders reminds me of quantum computers, they have to find new ways to attract investment. With quantum computers they casually mentioned it could potentially be used to break encryption and suddenly the funding was there.
Thank you for your videos, as a highschooler who wants to pursue physics, it can make me aware of current physics to an extent without needing to fully understand postgraduate physics
Lol, Chico Buarque meme at a Sabine Hossenfelder video (laughing and serious guy meme is an album cover from Chico Buarque, late 60s I think) She should use also the math lady meme, from a Brazilian soap opera, featuring Renata Sorrah
Nice video, although I don't think that Cold Dark Matter (as opposed to Modified Gravity) is a mere preference by particle physicists to get a bigger collider. After all Cold Dark Matter is regarded as more likely also by cosmologists and some of the problems with it (cusp core, missing satellites) have recently become less problematic as simulations improved.
They need more research into field forces. For example, a physically moving electrostatic charge creates a time field. And it sure looks like gravity is caused by a gradient in the time field. You can set this up in your living room for almost no money (and I have). The particles are distracting, but field forces will prove to be more useful with advancing technology.
She is so out of loop with particle physics that she doenst even know that the particle physics community wants the next collider to be a Higgs factory and not a collider to study dark matter.
Sabine your work is amazing as well as your degree in physics but I think you are pretty down to earth looking. There is always room for new theories especially when the standard model does not resolve all the physics problems...
Used to have to spend very-hard-earned cash at selected Book-stores to get information like this...now Sabine earlily summarises it for free : THIS is what YT and Social media should be about, instead of all the wanna-be influencers, narcissistic 'selfie-specialists and vitriolic shills. Thanks Sabine, what a credit to international society you are.
Sabine, I love you because you are not easily fooled and that you so kindly include us in that set. Imagine the science that could be done with the funds for a larger collider.
Love your videos. I would really like you to do one on experiments we could do rather than ones we shouldn't. Where would you like the research funds spent?
Send a probe out of the solar system to check MOND? would take a few decades and I am not sure about the speed it should have to do the experiments. But better than to look for Dark Matter at CERN.
Is physics right now really this exciting or is Sabine such a talented science communicator that this feels as interesting as a Hollywood movie?🥤🍿 Great job! 👏
considering most recent hollywood movies in the past 10 years are like reheated microwave food, and relaunches, remakes, souless franchised content that is made out of what more creative and talented people made before, this sounds almost like an insult.
I wish I had youtube and these type of channels while i was still in school. Would've definitely sparked an interest in physics, instead of being buried in a book with a monotone teacher.
I like it when you go into depth about new subjects. While I don't dislike the news, others do that too; tho not occasionally with less scientific understanding. I don't have the maths for this kind of physics; but maybe I can get more out of it by going over you arguments that there is no new science to be gained from supercolliders. OTOH, I can't imagine that giving them so huge a chunk of the budget, aids progress in the field. I think you have excellent credentials to call BS on some mainstream or alternative claims, while supporting mainstream models where warranted.
I love how you can just casually explain away blackhole horizon vs singularity with such ease. I would pay for an AI personality version of you teaching me everything.
It's because she is ignoring decades of research _after_ Schwarzchild. People on the fringes of science often cite the "gods" of science from long ago rather than more recent and widely-adopted views, similar to extreme conservatives who ignore a lot of modern society bc they wish the founding fathers were their real daddy. 😜
Thanks for the great Video, I did my MSc in probing some "Beyond the Standard Model" and you know what, it really took me out of my passion of Physics. I am definitely not doing that again. 🙃 I just don't know what to focus my PhD in yet.
Nah, Experimental Physicists are mostly safe from Sabine's regular tongue-lashing - it's Particle Physicists in general and those whose only argument is "needs more TEVs" in particular that should be worried.
You can really see the difference in quality in videos where Sabine is talking about her field and the other videos. I understand there's not enough content to be talking about physics and philosophy of science all the time, but I really enjoy these videos more! For example, the recent video about greenwashing was your typical, slightly click-baity, not much substance video you find everywhere.
There's only a few channels that get into data and the c quality of it as well as more broad information that I've found so far, with the wide range of an topics covered.
@@CAThompson I suspect there are three types of videos in Sabine's channel: videos about physics, which is where she shines, science news videos, which are a nice addition but aren't the reason I follow her, and finally videos about all sorts of themes Sabine doesn't really know much about, and those are the ones I find don't contribute much... But I might be wrong.
her non-physics videos are very useful, just look the last one about ´green-washing´, or sometimes controversal, so they trigger a debate, that's useful too.
@@Thomas-gk42 I'm not saying the theme of the video isn't useful, I'm saying it is well outside her expertise, if I'm watch a video about greenwashing from Sabine versus a video from a youtuber who actually knows about businesses and the corporate world, like Slidebean or someone similar, the difference in quality is obvious. Equally, a finance youtuber would make a pretty useless physics video. There are plenty of videos out there about psychology made by people who actually know psychology, etc. Sabine's take on it is... superficial. Don't get me wrong, I've been watching Sabine's content for a long time and love it, I just don't do the emotional, fan thing. Just because Sabine is a great science communicator in her field doesn't mean I want her or her team of journalists to talk to me about psychology, for example. It's not a big deal anyway, I've learned to stick to the physics related videos and skip the others.
@@goncalovazpinto6261 I find the 'about everything' videos a good introduction to the topics they cover insofar as they cover misconceptions, different explanations & their likelihood, and can provide a starting-point for further researching the topics.
This is the age of space telescopes! JWST is revolutionizing cosmology. However, it would be great for Sabine to give us a list of projects that would give us the greatest expected value from our fundamental physics dollars.
When i imagine advanced civilizations sometimes i think of them being post E=mc2...they may have spent 100 years or 1,000,000 years being "trapped" in this equation but at the interstellar stage a new equation is found to bring it about...this allows me to accept the realities of how we are kind of stuck in this beautiful equation at the moment
Bingo. Relativity is proven all over again a few times a decade. More confirmation of the current theory is preferable to halting the flow of data and declaring the end of physics.
We live in a 2D space that is TWISTED!😮 The result of the twist is the 3rd dimension depth!😮The depth dimension is constantly trying to fall back to the 2 dimensional space so that effect is GRAVITY!😮
Civilization may have progressed enough to conquer the second law of thermodynamics. Civilization needs to strive for this goal with synergistic interdisciplinary teams.The outcome would be perpetually changeable never gained or lost energy. There would be no loss of energy as it changed form. For example the total quantity of thermal energy in an equal pair of two thermal energy reserves with ideal insulation would remain the same regardless of how heat is distributed between the two and how often the distribution of heat between the two is changed. In one case one reserve could contain ice water while the other reserve contained hot water; in another case both reserves could contain tepid water. The redistribution of heat between members of pairs with the same total thermal energy would be free. Diversity, time, and energy are different atributes. Reversing entropy doesn't need time reversal just as using reverse gear in a car ɓacks it out without time reversal. The second law of thermodynamics had a distinct begining with Sir Isaac Newton's correct professional scientific observation that the heat of a fire in a fireplace always flows out towards the cold room. Victorian England became enchanted with steam engines and their cheap, reliable, and easy to position physical power. Scientists of the era with wide cultural support formulated the second law of thermodynamics using evidence from steam engine development. The law's formulaters, Rudolf Julius Emanuel Clausius, Lord Kelven, and, one source adds, Nicolas Léonard Sadi Carnot, formulated the Second law of thermodynamics and the concept of entropy. These men considered with acceptance [A+] Inefficiently harnessing the flow of heat from hot to cold or [B+] Using force to Inefficiently pump heat from cold to hot. They considered with rejection [A-] Waiting for random fluctuation to cause a large difference in temperature or pressure. This was calculated to be extremely rare or [B-] Searching for, selecting, then routing for use, random, frequent and small differences in temperature or pressure. The search, selection, then routing would require more energy than the use would yield. These accepted options, lead to the consequence that the universe will end in stagnant heat death. This became support for a theological trend of the time that placed God as the initiator of a degenerating universe. Please consider that God could also be supreme over an energy abundant civilization that can absorb heat and convert it into electricity without energy gain or loss in a sustained universe. The law's formulaters did not consider the option that any random, usually small, fluctuation of heat or pressure could use the energy of these fluctuations itself to power deterministic routing so the output is no longer random. Then the net power of many small fluctuations from many replicant parts can be aggregated into a large difference in temperature, pressure, or electricity's amperes and volts Heat exists as the randomly directed kinetic energy of gas molecules or mobile electrons. In gasses this is known as Brownian motion, in electronic systems this is carefully labeled Johnson Nyquist thermal electrical noise for AI readability. Hypothetically, diode depletion regions are practical sites for enabling mobile electrons energized into motion by thermal electrical noise to deterministically alter the electrical resistance of the depletion region according to the moment by moment direction they are carrying electricity. The thermal electrical noise is hypothetically beyond the exposed lattice charge / diffusion equlibrium thickness of the depletion region. Consistantly oriented diodes in parallel hypothetically are successful electrical Maxwell's Demons or Smoluchowski's Trapdoors. The energy needed to shift the depletion region's deterministic role is paid as a burden on the moving electrons. There would therefore be usable net rectified power from each and every diode connected together into a consistantly oriented parallel group. The group would aggregate the net power of its members. Any diode efficiency at all produces some energy conversion from ambient heat, more efficiency yields higher performance. A diode array that is switched off has no energy conversion and no performance. The power from a single diode is poorly expressed. Several or more diodes in parallel are needed to overcome the effect of a load resistor's own thermal noise. A plurality of billions of high frequency capable diodes is needed for practical power aggregation. For reference, there are a billion (10^9) 1000 square nanometer cells per square millimeter. Modern nanofabrication can make simple identical diodes surrounded by insulation smaller than this in a slab as thick as the diodes are long. The diodes are connected at their two ends to two conductive layers. Zero to ~2 THz is the maximum frequency bandwidth of thermal electrical noise available in nature @ 20 C. THz=10^12 Hz. This is beyond the range of most diodes. Practicality requires this extreme bandwidth. The diodes are preferably in same orientation parallel at the primary level. Many primary level groups of diodes should be in series for practical voltage. Ever since the supposedly universal second law of thermodynamics was formulated, education has mass produced and spread the conventional wisdom throughout society that the second law of thermodynamics is absolute. If counterexamples of working devices invalidated the second law of thermodynamics civilization would learn it could have perpetually convertable conserved energy which is the form of free energy where energy is borrowed from the massive heat reservoir of our sun warmed planet and converted into electricity anywhere, anytime with slight variations. Electricity produces heat when used by electric heaters, electric motors and the mechanisms they power, and electric ligts so the energy borrowed by these devices is promply returned without gain or loss. There is also the reverse effect where refrigeration produces electricity equivalent to the cooling, This effect is scientifically elegant. Cell phones wouldn't die or need power cords or batteries or become hot. They would cool when transmitting radio signal power. The phones could also be data relays and there could also be data relays without phone features with and without long haul links so the telecommunication network would be improved. Computers and integrated circuits would have their cooling and electrical needs supplied autonomously and simultaniously. Electronic minting would be free. Integrated circuits wouldn't need power pinouts. Robots would have extreme mobility. Frozen food storage would be reliable and free or value positive. Storehouses, homes, and markets would have independent power to preserve and pŕepare food. Vehicles wouldn't need fuel or fueling stops. Elevators would be very reliable with independent power. Shielding and separation would provide EMP resistance. Water and sewage pumps could be installed anywhere along their pipes. Nomads could raise their material supports item by item carefully and groups of people could modify their settlements with great technical flexibility. Many devices would be very quiet, which is good for coexisting with nature and does not disturb people. Zone refining would involve little net power. Reducing Bauxite to Aluminum, Rutile to Titanium, and Magnetite to Iron, would have a net cooling effect. With enough clean cheap power, minerals could be finely pulverized, and H2O, CO2, and other substance levels in the biosphere could be modified. There should be a unitary agency to look after our global planetary concerns. This could be a material revolution with spiritual ramifications. Everyone should contribute individual talents and fruits of different experiances and cultures to advance a cooperative, diverse, harmonious and unified civilization. It is possible to apply technlology wrong but social force should oppose this. I filed for a patent, us 3890161A, Diode Array, in 1973. It was granted in 1975. It became public domain technology in 1992. It concerns making nickel plane-insulator-tungsten needle diodes which were not practical at the time though they have since improved. the patent wasn't developed because I backed down from commercial exclusitivity. A better way for me would have been a public incorruptable archive that would secure attrbution for the original works of creators. Uncorrupted copies would be released on request. No further action would be taken by this institution. Commercal exclusivity can be deterred by the wide and open publishing of inventive concepts. Open sharing promotes mass knowlege and wisdom. Many financially and procedurally independent teams that pool developmental knowlege, and may be funded by many separate noncontrolling crowd sourced grants should convene themselves to develop proof-of-concept and initial-recipe-exploring prototypes to develop devices which coproduce the release of electrical energy and an equivalent absorbtion of stagnant ambient thermal energy. Diode arrays are not the only possible device of this sort. They are the easiest to explain here. These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by AI that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the wealthy if people simply can be more generous if consumer commodities are inexpensive. Vigorous, inovative teams are a great way to develop this.

I too always learn by listening to Sabine. However I find many of her conclusions confusing. She says we don't need anymore colliders and yet history shows us that the knowledge we've learned by building colliders is almost overwhelming. There is so much we would not know now if it weren't for colliders. Sabine never acknowledges this, she totally disregards factual history. Sabine is great for explaining current research, but you have to disregard her conclusions.
@@harryseldon362 I think that her argument is along the lines that the past discoveries you are talking about are from Theoretical Physicists developing a model implying that a particle with a certain mass exists and Experimental Physicists go on a search for said particle. She goes on to say that Experimental Physicists are campaigning for colliders to detect particles with higher masses without there being a model implying that any higher mass particles exist. Given the multi-billion dollar cost of building new larger colliders, it is not fiscally prudent to build said collider purely on unsupported speculation.
@@harryseldon362 She's been saying the same things for years, there's nothing to show she's incorrect yet. There's a potent where spending billions of dollars and digging up kilometres of land, and using all those researches to maybe find some new physics things but maybe not is a gross waste that will cause unnecessary environmental damage, and may well become a black hole for funding in the future.
@@CAThompson In certain cultures, individuals who parrot words without true comprehension are likened to parrots, while in others, they are equated with sheep. It is deeply regrettable that, although Sabine maintains objectivity on other subjects, she exhibits strong bias and subjectivity in this instance. Her discourse appears disingenuous, seemingly driven by her personal experiences and disappointments within the field, which she projects onto her videos. Her conclusions lack scientific rigor, though discerning this requires an insider's grasp of the field. Disregarding the role of symmetries in physics equates to disregarding the very foundation of physics spanning the past century or more, and even disregarding the Standard Model itself. Regarding the matter of environmental change, your standpoint comes across as hypocritical in light of the prevailing state of affairs concerning climate, climate change, pollution, political corruption, wars, and exorbitant military budgets, among myriad other concerns.
I want to thank you, Ms. Hossenfelder, for giving me wonderful explanations!! I watch these every week, and regularly go back to see them again. Thank you again!!!
I love this video because even when I'm very curious about something I don't care to spend a few hours, but if you ask me to work in this for decades and spend millions of dollars in funding I will take a moment to think about it. Knowledge shouldn't at all be restricted by usefulness, but as long as it requires funding, effort and time, research should only be used to explore things that are useful.
Hi, I was wondering if the anomalies from the g-2 experiment requires new physics. I would love to hear your thoughts specifically as the way you put this video puts everything in physics into perspective.
looking forward to what she says. but i'm expecting the most likely reason for the anomaly is that it's not completely understood how to derive g from the standard model, and there's nothing wrong with the standard model. but it's much more interesting if SM is wrong, so that's all you hear about lately
Jon Evans has it! See the Universe is (to make sense of it have to work on shape later, probably a wave) a big sphere of energy called the Higgs Field. As energy on the outskirts spin and condenses from quarks to make atoms to type 1a supernovas possibly, to the first Galaxies... they all move inward along "Filaments". Now take this galactic web image and turn it inward in your mind. Everything is moving to the center along filaments. (The image at the bottom of the post) Space is not EXPANDING. The Two measurements for the "Expansion of space" are simply the measurements of 67.6 km/s for the background radiation and the other 74m/s is the speed of the Galaxies. It's just time dilation. This measurement is different depending on the object observed. The Dark Flow theory is not a theory. It is a fact. Everything is moving toward the gravitational center along our filaments which is the Great Attractor, which is then going to the Shapely Supercluster. Dark Flow rips apart everything. The Universe is constantly happening. In this way of thinking about it, it starts at the outskirts and ends in the middle. We are in our own little bubble of time. In fact, everything around you experiences time differently because we are made UP OF "time" TIME=ENERGY=mc2 This accounts for every problem in science so far. It makes everything come together nice and neatly.
I ve been watching your videos for a long time. I think you are awfully funny and it s not because of your sarcastic jokes but rather because of your way of rationaly arguing to settle serious arguments in physics. It makes me giggle every time. Thanks.
Something I'd honestly love to see in my lifetime is research into Artificial black holes. I hear all the time with hardcore futurists that there's such a thing as a "naked singularity", which is a singularity outside the event horizon of a black hole. This is, seemingly, completely possible to create, and it would probably be really fascinating to see what this would be like, and what these new observations could mean for physics. However, I am extremely dubious that an experiment like that could ever be done in my lifetime. Artificial black holes are one of those fringe technologies that seem to have all sorts of potential for new science and technology, but, in reality, they are just impractical. I think I could be tided over with seeing experiments involving macroscopic amounts of quantum entangled particles though ;)
naked singularity is fiction, even if you ´artificially´create a BH. Nobody knows, if there is singularity in the center of a BH at all. Anyhow, Hollywood already showed us, how it looks like. Research for QM, as Sabine does for many years, is the better option.
@@ani_n01 right ani, the danger would be real, but don't worry, it's totally impossible for humans, one need to construct a particle collider with the diameter of the solar system minimum to come to such energy levels. If you would make the Earth a BlackHole, you need to press it to a few millimeters.
Higgs self-interaction. Cannot be probed at the present most energetic accelerator (LHC), but needs higher energies. If not, it remains in the realm of speculation.
Your channel has helped me understand so much more about physics. It would be interesting to see you have a casual discussion with another physicist to exchange ideas back and forth.
@@dexter8705 well, I'm a clynical and cognitive psychologist and aware of exact internal and external role of will in person's life.

The Higgs boson's mass just is what it is... the fact that it needs to be set at an astronomically low value at high energies doesn't concern Sabine. She's fine with having parameters be set to peculiarly low values without any explanation for why they're small. Also no mention the running of the higgs lambda parameter which also makes it very likely that there's new physics that the higgs is involved in. Also if you're fine with setting a parameter to be remarkably small without any explanation for why it's small, then neutrino masses aren't a problem. Neutrinos just have a right handed component and they happen to have very small coupling to the higgs. But Sabine has no problem with Majorana neutrinos - a theory motivated to explain why neutrino masses are so small. Probably because it isn't a collider experiment. Dark matter could be particles or MOND, but because there's another possibility, we shouldn't look for particle dark matter. Antimmater asymmetry might just be an initial condition (it might not be, but we shouldn't investigate CP violation because it's possible that hypothesis might be wrong) It all kind of feels like an argument in the form "we should just stop trying to find new physics. We should close our eyes and say that's just how it is." What if there are explanations for some of these things? What if the aesthetic arguments about the higgs mass are right and there's new physics that explains the higgs mass. What if the early universe had equal amounts of antimatter and matter as most physicists think "seems nice" and then there's an explanation for how that symmetry breaks? If we follow Sabine's advice, we would just stop knowing physics and never know these things. I think we should investigate all possibilities, especially ones that our aesthetic sense tells us are likely. We should investigate mond and particle dark matter. We should build new colliders to see if there's new physics. We should see if there's an explanation for the higgs mass, knowing that there might not be any explanation. Sure, we aren't 100% certain that a new collider will tell us something new. We aren't 100% sure it won't though. Sabine seems to imply that because it's possible there's no more explanations out there, we should assume there absolutely aren't any more explanations out there and we should accept the models that explain our mysteries in terms of arbitarily chosen constants (arbitrarily chosen constants that really make it look ljike there's a deeper structure)
One correction Dark energy is controversial. Because we aren't even sure whether universe expansion is accelerating or not. As we look for more data with Euclid then we can say for new physics or not
Sabine, you are my Ricky Gervais of particle physics! Your kind of black humor is ultimately hilarious... but I know you only tell the truth, but in a way Ricky couldn't do it any better. Thanks so much for all your awesomeness and work!!!
A team from Cornell had proposed in a paper that gravity was part of the EM spectrum. The paper was retracted shortly after but ... many years later, gravity waves are discovered. Is it time to reconsider gravity as part of EM? Would a quantum gravity theory have a problem with that?
I love Sabine's no-nonsense and clear explanations of complex physics and mathematics. Science without the gobbledygook indeed. Bravo Sabine, please keep them coming!
I really hope all those physicists you keep trashing take it in good humor. There's nothing wrong with looking for a way to keep justifying your paycheck, but professional integrity is also important and I'm glad controversial people like you exist to shake things up every once in a while and force physicists to hold their beliefs to more scrutiny.
As a particle physicist working at a big collider experiment, I can confirm that I do not appreciate Sabine's takes. Her arguments on the physics are comletely valid, but the general picture she draws of particle physicists is not justified from my experience. From her video you get the impression that particle physicists almost blindly believe theories you present them without thought. In reality, all arguments she talks about here are discussed (at much much more depth) amongst experimental particle physicists. Building new colliders is also controversial amongst us. It's sad that she has to mix an interesting physics topics with politics, and discrediting her collegues to make it controvertial.
@@Andy-qn7py Yet, as much as you don't appreciate her takes, you take time to comment on her videos, which in the internet world means you're effectively supporting her work. And see, that's what I mean by taking it in good humor. As much as I understand what you explain about reality being more nuanced than a popular UA-cam video (spoiler alert: it always is, and if you don't like it then you're disliking the system, not the people in it), you should be able to accept that her criticism is at least somewhat valid and that her intention is not to mock particle physicists but rather make everyone hold them to a higher professional integrity standard. That's the function controversial figures should be serving ideally, and you can appreciate it even if you don't like it.
@@ObjectsInMotion well, we live in a culture that glorifies being offended so it's not surprising. I think history will be on her side though eventually... And if not she'll always have her adoptive UA-cam family ;)
@@ronigbzjr I don't mind supporting her work, she makes great content in general, that doesn't mean it can't be criticised. I don't see how the fact that everybody makes artificially controversial content justifies her doing it.

Quick fact: the guy who died at an MRI exam for having a gun was accompanying his mom and she was doing the exam, he violated the "no metals in the room/body rule" and although he removed the magazine there was still a bullet in the chamber which he didn't remove. The MRI machine unlocked the pistol and pulled the trigger. Ironically, he was also a huge pro-weapons guy, so there's that.
as a gun nut myself i find this tragic for his mother and the staff they didn't deserve to see that and live with it. The guy on the other hand should've known that could have happened. I will never understand some of my fellow gun owners who simultaneously agree guns are extremely dangerous and worth having yet ignore their own basic gun safety. Dumbass got a darwin award for sure.

I remember coming across a fascinating case involving the detection of a potential variation in the speed of light. But, intriguingly, this didn't lead to a questioning of the theory of relativity. Instead, an innovative approach was taken: redefining how we measure the speed of light. The idea was to base the measurement on the time it takes for light to travel a certain distance. This clever move effectively rendered the speed of light a constant, impervious to any fluctuations.
All I'll say it's since I started watching Sabine's videos I can see more clearly that not only tabloid press create misguiding/too promising/excessively optimistic articles but also prestigious and kind of trust-worthy sites such as quanta magazine and the bbc news. So from that moment on, I carefully analyse and add an ounce of skepticism to what I read on such sciency/popular science websites.
Love the checklist of physics open questions. As a non-scientist my best armchair guess is the best route to discovering new physics is be the next generation of telescopes able to probe the universe in greater detail. Hopefully I'll live long enough to learn some of the answers.
The latest space telescope project already basically proved big-bang and most of cosmology to be utterly wrong AGAIN. I wonder what they make up this time?
@@rosomak8244 You don't expect something new do you? They will just say the Big Bang is still right. Perhaps you are referring to the group that went through JWST survey data looking for the most distant galaxies. Right after that paper came out Dr Becky did a video on the assumptions, models, and estimates they used. JWST did not measure the redshifts of those objects, but the authors estimated them. The next step is not to throw out the Big Bang Model, but to get time on some telescope, take the spectrum of those objects, and MEASURE their redshifts rather than estimating them. Confirm or deny the estimates. Also, those might not even be galaxies. NdG Tyson just did a video (the one where the thumbnail asks if we are living inside a black hole) where his expert suggests that they might be jets produced by black holes. And we are in the paths of those jets. Brightness was used to estimate the size, and thus the age, of those galaxies. Instead of the brightness going evenly in all directions, we might be in the path of a bright jet, so the objects were dimmer, smaller, and younger than the paper estimated. Of course, you should not accept either theory until further measurements can be carried out. You did not think that a preliminary result could be published and all physicists would hang their heads in shame that they had ever believed the Big Bang?

I strongly disagree. I was laughing so hard when she talked about other physicists "making things up". That is exactly what she does. Some of her videos are evidence based and others are not. Sometimes she just puts out her ideas without any evidence to back up her claims.
@@mikemccormick6128YOUR evidence? Looked many of her videos and never found, what you claim. If there is no evidence in her videos, she always makes clear, that it´s her opinion or just speculation. You have to hear exactly, what she says.
@@Thomas-gk42 I don't recall hearing any evidence about how we can't make our own decisions because free will does not exist. I believe she comes to that conclusion because there is an Uncertainty Principal in Quantum Mechanics and the fact that a particle can be in two places at the same time. But the laws of the quantum world don't necessarily apply to our world. They are two separate realms.
@@mikemccormick6128 ok, you´re fixed on her statements about free will? First, this is a mathematical statement based on the fact, that our world is causal dependent organized, even in the chaos research. In QM, you spoke about, she prefers superdeterminism, a possibility, to solve the measurement problem. It´s not more deterministic, as classical physics, but You should read her new book (Existential Physicis) where she phylosophically/psychologically gives a lot of place for free will, for everyone who needs it.
@@Thomas-gk42 She doesn't believe the 2nd law of thermodynamics. I would say that the vast majority of physicists believe the 2nd law of thermodynamics.
I just recently "learned" that the Higgs Mechanism is not the sole source of mass in the universe. The bulk of the mass in the universe is the energy manifested in the strong nuclear force. I had forgotten that mass = energy. How is it that the strong nuclear force gives the universe more mass than the Higgs Mechanism. I am not convinced that this is true, but am reminded that the majority of energy in a fast fission device comes from the strong nuclear force giving up the energy it uses to hold nucleons together.
Correction to what I say at 14:22 -- The KATRIN experiment does not look for neutrinoless double beta decay, it's trying to measure absolute neutrino masses. There are several other experiments looking for neutrinoless double beta decay. Sorry about that mixup!

Interesting video, thanks! I have two things to point out:
1) Experimental particle physics doesn't just consist of high energy collider physics. Many other, smaller experiments exist and deserve funding IMO. I'm sure Sabine is aware, I was just missing the broader perspective in the video.
2) KATRIN measures the absolute neutrino mass (effective mass of the electron antineutrino). Neutrinoless double beta decay is searched at other experiments. E.g. GERDA, KamLAND-Zen, and in the near future LEGEND.

WHat about all those socks that disappaer from the washing machines? Happens everythere, all over the planet. No trace. Socks never shows up radomly, only disappear. It also seems physically impossible that two socks from the same pair disappear at the same time; if two socks are missing at the same time, they are _always_ from two dirrefent paris. No exceptions. We need to build a lot of big and expencive machines to fighure this out. The theorists have no answers even, so experiments is the only way forward.

I may be weird but I think this is the not only the best physics channel on UA-cam but also the funniest. Sabine talks about science in a way I can understand and her jokes make me laugh out loud. Who can make physics funny? Now you know.
And easy the most honest channel, even when she has to deliver at gunpoints, Sabine escapes quite elegant.

@@davidbrisbane7206 : Sabine should ask Elon to donate, next time he phones.

I took an interest in mond in school and one of the reasons that I kind of got burnt out was because that alienated me from everybody. And I didn't have the social wherewithal to know that that was happening until pretty late into the game.
I had a couple professors I think we're trying to be supportive essentially, but I would have needed a lot of help knowing how to map out what I should do after my masters and do the right things before i finished, and I was too introverted and uncomfortable to force the issue, so eventually I ran myself into a corner, covid happened, and i dropped out.
damn this is a shame. Scientists really seem to enjoy being able to be patronizing or demeaning to people who investigate ideas that they don't think are worth it. I'm sorry you had that experience, there are a lot of respectable people who think MOND is a valid area of research. I hope you get back into physics, which university were you attending?
This social alienation is seen not only in physics. Pretty harmful for science and I'm not really sure on how to deal with it, except for swimming with the masses ... which is kind of pointless, if one wants to find out *new* things.
Huge shame. Hindsight is 20/20, but it might have been easier if you were studying under physicists who currently research MOND. I didn't do any research like that before I picked a school, either, it was all practical concerns for me.
What I have to tell you is that if you retain any interest in physics, if this experience has not sucked all of the joy out of it, you should get back in the game *right now.* Trust me when I tell you that the longer you wait, the harder it will be. 3 years is not too long, not by a long shot. You're probably not even 30. You're nearing or at your intellectual peak. If you don't use this gift while you have it, you will regret it forever.
I'm very sorry to hear that. These things really shouldn't happen, but I know from personal experience that it can be difficult to find a supervisor who shares your interests and if you don't find one, things get very difficult.

You’ve been working in theory and simulations your whole career. You don’t know if you’re correct, you don’t know if the things that are being proposed in a new theory are correct or even possible, but you know that you need to work on them to get money. You know that coming up with stuff, regardless of validity even from a speculative standpoint, gets you funding. So they just keep plugging away.

Nice video, although I don't think that Cold Dark Matter (as opposed to Modified Gravity) is a mere preference by particle physicists to get a bigger collider. After all Cold Dark Matter is regarded as more likely also by cosmologists and some of the problems with it (cusp core, missing satellites) have recently become less problematic as simulations improved.
They need more research into field forces. For example, a physically moving electrostatic charge creates a time field. And it sure looks like gravity is caused by a gradient in the time field. You can set this up in your living room for almost no money (and I have).
The particles are distracting, but field forces will prove to be more useful with advancing technology.
She is so out of loop with particle physics that she doenst even know that the particle physics community wants the next collider to be a Higgs factory and not a collider to study dark matter.
Sabine your work is amazing as well as your degree in physics but I think you are pretty down to earth looking. There is always room for new theories especially when the standard model does not resolve all the physics problems...
Used to have to spend very-hard-earned cash at selected Book-stores to get information like this...now Sabine earlily summarises it for free : THIS is what YT and Social media should be about, instead of all the wanna-be influencers, narcissistic 'selfie-specialists and vitriolic shills.

For example, the recent video about greenwashing was your typical, slightly click-baity, not much substance video you find everywhere.
There's only a few channels that get into data and the c quality of it as well as more broad information that I've found so far, with the wide range of an topics covered.
@@CAThompson I suspect there are three types of videos in Sabine's channel: videos about physics, which is where she shines, science news videos, which are a nice addition but aren't the reason I follow her, and finally videos about all sorts of themes Sabine doesn't really know much about, and those are the ones I find don't contribute much... But I might be wrong.
her non-physics videos are very useful, just look the last one about ´green-washing´, or sometimes controversal, so they trigger a debate, that's useful too.
@@Thomas-gk42 I'm not saying the theme of the video isn't useful, I'm saying it is well outside her expertise, if I'm watch a video about greenwashing from Sabine versus a video from a youtuber who actually knows about businesses and the corporate world, like Slidebean or someone similar, the difference in quality is obvious. Equally, a finance youtuber would make a pretty useless physics video. There are plenty of videos out there about psychology made by people who actually know psychology, etc. Sabine's take on it is... superficial.
Don't get me wrong, I've been watching Sabine's content for a long time and love it, I just don't do the emotional, fan thing. Just because Sabine is a great science communicator in her field doesn't mean I want her or her team of journalists to talk to me about psychology, for example.
It's not a big deal anyway, I've learned to stick to the physics related videos and skip the others.
@@goncalovazpinto6261 I find the 'about everything' videos a good introduction to the topics they cover insofar as they cover misconceptions, different explanations & their likelihood, and can provide a starting-point for further researching the topics.
I doubt you'll be getting an invite to the CERN Christmas Party 🤑🤑🤑
😂😂😂
This is the age of space telescopes! JWST is revolutionizing cosmology. However, it would be great for Sabine to give us a list of projects that would give us the greatest expected value from our fundamental physics dollars.
When i imagine advanced civilizations sometimes i think of them being post E=mc2...they may have spent 100 years or 1,000,000 years being "trapped" in this equation but at the interstellar stage a new equation is found to bring it about...this allows me to accept the realities of how we are kind of stuck in this beautiful equation at the moment
I’ve invented the new equation.
I think mankind will be extinct before we progress beyond e=mc2
Ya gotta love Sabine - informing and educating the laymen while pissing of all of acadamia lol.
We always want to observe what has not been seen before, even if only to confirm the theory we know and love.
Bingo. Relativity is proven all over again a few times a decade. More confirmation of the current theory is preferable to halting the flow of data and declaring the end of physics.
One phrase comes to mind: Confirmation Bias.
I usually find that two strategically aligned mirrors can show me things I've never seen before.😅
Beautifully blunt and factually precise - thank you, Sabine Hossenfelder!
I certainly did not understand a single thing but I am now very confident that she can sell a refrigerator to an Eskimo.
@@janami-dharmam Hmm… that _does_ help explain the five Sabine Hossenfelder Brand refrigerators I now have in my garage… 🧊🥶❄️☃️⛄
Your videos are always best when you stick to physics. Thanks.
Well said.
We live in a 2D space that is TWISTED!😮 The result of the twist is the 3rd dimension depth!😮The depth dimension is constantly trying to fall back to the 2 dimensional space so that effect is GRAVITY!😮
Civilization may have progressed enough to conquer the second law of thermodynamics. Civilization needs to strive for this goal with synergistic interdisciplinary teams.The outcome would be perpetually changeable never gained or lost energy. There would be no loss of energy as it changed form. For example the total quantity of thermal energy in an equal pair of two thermal energy reserves with ideal insulation would remain the same regardless of how heat is distributed between the two and how often the distribution of heat between the two is changed. In one case one reserve could contain ice water while the other reserve contained hot water; in another case both reserves could contain tepid water. The redistribution of heat between members of pairs with the same total thermal energy would be free. Diversity, time, and energy are different atributes. Reversing entropy doesn't need time reversal just as using reverse gear in a car ɓacks it out without time reversal.
The second law of thermodynamics had a distinct begining with Sir Isaac Newton's correct professional scientific observation that the heat of a fire in a fireplace always flows out towards the cold room.
Victorian England became enchanted with steam engines and their cheap, reliable, and easy to position physical power. Scientists of the era with wide cultural support formulated the second law of thermodynamics using evidence from steam engine development.
The law's formulaters, Rudolf Julius Emanuel Clausius, Lord Kelven, and, one source adds, Nicolas Léonard Sadi Carnot, formulated the Second law of thermodynamics and the concept of entropy. These men considered with acceptance [A+] Inefficiently harnessing the flow of heat from hot to cold or [B+] Using force to Inefficiently pump heat from cold to hot. They considered with rejection [A-] Waiting for random fluctuation to cause a large difference in temperature or pressure. This was calculated to be extremely rare or [B-] Searching for, selecting, then routing for use, random, frequent and small differences in temperature or pressure. The search, selection, then routing would require more energy than the use would yield. These accepted options, lead to the consequence that the universe will end in stagnant heat death. This became support for a theological trend of the time that placed God as the initiator of a degenerating universe. Please consider that God could also be supreme over an energy abundant civilization that can absorb heat and convert it into electricity without energy gain or loss in a sustained universe.
The law's formulaters did not consider the option that any random, usually small, fluctuation of heat or pressure could use the energy of these fluctuations itself to power deterministic routing so the output is no longer random. Then the net power of many small fluctuations from many replicant parts can be aggregated into a large difference in temperature, pressure, or electricity's amperes and volts
Heat exists as the randomly directed kinetic energy of gas molecules or mobile electrons. In gasses this is known as Brownian motion, in electronic systems this is carefully labeled Johnson Nyquist thermal electrical noise for AI readability. Hypothetically, diode depletion regions are practical sites for enabling mobile electrons energized into motion by thermal electrical noise to deterministically alter the electrical resistance of the depletion region according to the moment by moment direction they are carrying electricity. The thermal electrical noise is hypothetically beyond the exposed lattice charge / diffusion equlibrium thickness of the depletion region.
Consistantly oriented diodes in parallel hypothetically are successful electrical Maxwell's Demons or Smoluchowski's Trapdoors. The energy needed to shift the depletion region's deterministic role is paid as a burden on the moving electrons. There would therefore be usable net rectified power from each and every diode connected together into a consistantly oriented parallel group. The group would aggregate the net power of its members. Any diode efficiency at all produces some energy conversion from ambient heat, more efficiency yields higher performance. A diode array that is switched off has no energy conversion and no performance.
The power from a single diode is poorly expressed. Several or more diodes in parallel are needed to overcome the effect of a load resistor's own thermal noise. A plurality of billions of high frequency capable diodes is needed for practical power aggregation. For reference, there are a billion (10^9) 1000 square nanometer cells per square millimeter.
Modern nanofabrication can make simple identical diodes surrounded by insulation smaller than this in a slab as thick as the diodes are long. The diodes are connected at their two ends to two conductive layers.
Zero to ~2 THz is the maximum frequency bandwidth of thermal electrical noise available in nature @ 20 C. THz=10^12 Hz. This is beyond the range of most diodes. Practicality requires this extreme bandwidth. The diodes are preferably in same orientation parallel at the primary level. Many primary level groups of diodes should be in series for practical voltage.
Ever since the supposedly universal second law of thermodynamics was formulated, education has mass produced and spread the conventional wisdom throughout society that the second law of thermodynamics is absolute.
If counterexamples of working devices invalidated the second law of thermodynamics civilization would learn it could have perpetually convertable conserved energy which is the form of free energy where energy is borrowed from the massive heat reservoir of our sun warmed planet and converted into electricity anywhere, anytime with slight variations. Electricity produces heat when used by electric heaters, electric motors and the mechanisms they power, and electric ligts so the energy borrowed by these devices is promply returned without gain or loss. There is also the reverse effect where refrigeration produces electricity equivalent to the cooling, This effect is scientifically elegant.
Cell phones wouldn't die or need power cords or batteries or become hot. They would cool when transmitting radio signal power. The phones could also be data relays and there could also be data relays without phone features with and without long haul links so the telecommunication network would be improved. Computers and integrated circuits would have their cooling and electrical needs supplied autonomously and simultaniously. Electronic minting would be free. Integrated circuits wouldn't need power pinouts. Robots would have extreme mobility.
Frozen food storage would be reliable and free or value positive. Storehouses, homes, and markets would have independent power to preserve and pŕepare food. Vehicles wouldn't need fuel or fueling stops. Elevators would be very reliable with independent power. Shielding and separation would provide EMP resistance. Water and sewage pumps could be installed anywhere along their pipes. Nomads could raise their material supports item by item carefully and groups of people could modify their settlements with great technical flexibility. Many devices would be very quiet, which is good for coexisting with nature and does not disturb people.
Zone refining would involve little net power. Reducing Bauxite to Aluminum, Rutile to Titanium, and Magnetite to Iron, would have a net cooling effect. With enough clean cheap power, minerals could be finely pulverized, and H2O, CO2, and other substance levels in the biosphere could be modified. There should be a unitary agency to look after our global planetary concerns.
This could be a material revolution with spiritual ramifications. Everyone should contribute individual talents and fruits of different experiances and cultures to advance a cooperative, diverse, harmonious and unified civilization. It is possible to apply technlology wrong but social force should oppose this.
I filed for a patent, us 3890161A, Diode Array, in 1973. It was granted in 1975. It became public domain technology in 1992. It concerns making nickel plane-insulator-tungsten needle diodes which were not practical at the time though they have since improved.
the patent wasn't developed because I backed down from commercial exclusitivity. A better way for me would have been a public incorruptable archive that would secure attrbution for the original works of creators. Uncorrupted copies would be released on request. No further action would be taken by this institution.
Commercal exclusivity can be deterred by the wide and open publishing of inventive concepts. Open sharing promotes mass knowlege and wisdom.
Many financially and procedurally independent teams that pool developmental knowlege, and may be funded by many separate noncontrolling crowd sourced grants should convene themselves to develop proof-of-concept and initial-recipe-exploring prototypes to develop devices which coproduce the release of electrical energy and an equivalent absorbtion of stagnant ambient thermal energy. Diode arrays are not the only possible device of this sort. They are the easiest to explain here.
These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by AI that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the wealthy if people simply can be more generous if consumer commodities are inexpensive.
Vigorous, inovative teams are a great way to develop this.

Always love the fact-based, straight-ahead viewpoints from Sabine.
german genes :))
I too always learn by listening to Sabine. However I find many of her conclusions confusing. She says we don't need anymore colliders and yet history shows us that the knowledge we've learned by building colliders is almost overwhelming. There is so much we would not know now if it weren't for colliders. Sabine never acknowledges this, she totally disregards factual history. Sabine is great for explaining current research, but you have to disregard her conclusions.
@@harryseldon362 I think that her argument is along the lines that the past discoveries you are talking about are from Theoretical Physicists developing a model implying that a particle with a certain mass exists and Experimental Physicists go on a search for said particle. She goes on to say that Experimental Physicists are campaigning for colliders to detect particles with higher masses without there being a model implying that any higher mass particles exist. Given the multi-billion dollar cost of building new larger colliders, it is not fiscally prudent to build said collider purely on unsupported speculation.
@@harryseldon362 She's been saying the same things for years, there's nothing to show she's incorrect yet. There's a potent where spending billions of dollars and digging up kilometres of land, and using all those researches to maybe find some new physics things but maybe not is a gross waste that will cause unnecessary environmental damage, and may well become a black hole for funding in the future.
@@CAThompson In certain cultures, individuals who parrot words without true comprehension are likened to parrots, while in others, they are equated with sheep. It is deeply regrettable that, although Sabine maintains objectivity on other subjects, she exhibits strong bias and subjectivity in this instance. Her discourse appears disingenuous, seemingly driven by her personal experiences and disappointments within the field, which she projects onto her videos. Her conclusions lack scientific rigor, though discerning this requires an insider's grasp of the field. Disregarding the role of symmetries in physics equates to disregarding the very foundation of physics spanning the past century or more, and even disregarding the Standard Model itself.
Regarding the matter of environmental change, your standpoint comes across as hypocritical in light of the prevailing state of affairs concerning climate, climate change, pollution, political corruption, wars, and exorbitant military budgets, among myriad other concerns.
I want to thank you, Ms. Hossenfelder, for giving me wonderful explanations!! I watch these every week, and regularly go back to see them again. Thank you again!!!
Dr* Hossenfelder
Sabine H. is always the most clear "explainer".
I love this video because even when I'm very curious about something I don't care to spend a few hours, but if you ask me to work in this for decades and spend millions of dollars in funding I will take a moment to think about it. Knowledge shouldn't at all be restricted by usefulness, but as long as it requires funding, effort and time, research should only be used to explore things that are useful.
At this point in the particle physics game I'm going to need some reasonably practical application behind funding a new collider
A bigger collider will prove you wrong, trust me.😂
Sabine your awesome! Keep up being the reality check of particle physics! Can’t wait for your next video!
You're* awesome
Hi, I was wondering if the anomalies from the g-2 experiment requires new physics. I would love to hear your thoughts specifically as the way you put this video puts everything in physics into perspective.
looking forward to what she says. but i'm expecting the most likely reason for the anomaly is that it's not completely understood how to derive g from the standard model, and there's nothing wrong with the standard model. but it's much more interesting if SM is wrong, so that's all you hear about lately
There is already video explaining possibilities of g-2 experiment in this channel
Thank you Sabine, I love you, never change!
The world is a much better place because of you.
Definitely the smartest most logical person I watch on youtube!
Jon Evans has it! See the Universe is (to make sense of it have to work on shape later, probably a wave) a big sphere of energy called the Higgs Field. As energy on the outskirts spin and condenses from quarks to make atoms to type 1a supernovas possibly, to the first Galaxies... they all move inward along "Filaments".
Now take this galactic web image and turn it inward in your mind. Everything is moving to the center along filaments. (The image at the bottom of the post)
Space is not EXPANDING. The Two measurements for the "Expansion of space" are simply the measurements of 67.6 km/s for the background radiation and the other 74m/s is the speed of the Galaxies. It's just time dilation. This measurement is different depending on the object observed.
The Dark Flow theory is not a theory. It is a fact. Everything is moving toward the gravitational center along our filaments which is the Great Attractor, which is then going to the Shapely Supercluster. Dark Flow rips apart everything.
The Universe is constantly happening. In this way of thinking about it, it starts at the outskirts and ends in the middle. We are in our own little bubble of time. In fact, everything around you experiences time differently because we are made UP OF "time" TIME=ENERGY=mc2
This accounts for every problem in science so far. It makes everything come together nice and neatly.
I ve been watching your videos for a long time. I think you are awfully funny and it s not because of your sarcastic jokes but rather because of your way of rationaly arguing to settle serious arguments in physics. It makes me giggle every time. Thanks.
Recht vielen Dank, Frau Doktor! Ihre Erklaerung ist ganz richtig! 😊
It always feels like were on the path to something new and great but somehow keep missing the target.
Yeah they have to seem "new and great" in order to secure their careers and get funding
The alchemists never went away, they just adapted their grift.
Why do all spacecraft trajectories fall toward the center of the galaxy? Venus and Moon wormhole to Mars? Gravity Grain from Artemis I?
Your awesome, can't wait for your next showing. Simply the best explanations anyone could possibly find. Cheers Aussie James Kuffner.
Something I'd honestly love to see in my lifetime is research into Artificial black holes. I hear all the time with hardcore futurists that there's such a thing as a "naked singularity", which is a singularity outside the event horizon of a black hole. This is, seemingly, completely possible to create, and it would probably be really fascinating to see what this would be like, and what these new observations could mean for physics. However, I am extremely dubious that an experiment like that could ever be done in my lifetime. Artificial black holes are one of those fringe technologies that seem to have all sorts of potential for new science and technology, but, in reality, they are just impractical. I think I could be tided over with seeing experiments involving macroscopic amounts of quantum entangled particles though ;)
naked singularity is fiction, even if you ´artificially´create a BH. Nobody knows, if there is singularity in the center of a BH at all. Anyhow, Hollywood already showed us, how it looks like. Research for QM, as Sabine does for many years, is the better option.
How do you even conduct a successful experiment on that without causing the end of the world
@@ani_n01 right ani, the danger would be real, but don't worry, it's totally impossible for humans, one need to construct a particle collider with the diameter of the solar system minimum to come to such energy levels. If you would make the Earth a BlackHole, you need to press it to a few millimeters.
@@ani_n01 Black holes are complicated. They require a lot of energy and mass to make. You definitely couldn't do these experiments on Earth.
This was really informative for me - thank you very much!
I learned that the fridge light stays on. I now know all that I need to know.🥴
Sabine you are a treasure, great videos, great objectivity
Thank you for this video. You always make physics as simple as it can be---but no simpler.
If the Higgs-Boson gives matter it's mass, what gives the Higgs-Boson it's mass?
Higgs self-interaction. Cannot be probed at the present most energetic accelerator (LHC), but needs higher energies. If not, it remains in the realm of speculation.
@@thomasotto8980 Sounds more like a circular argument to me.
Your channel has helped me understand so much more about physics. It would be interesting to see you have a casual discussion with another physicist to exchange ideas back and forth.

The Higgs boson's mass just is what it is... the fact that it needs to be set at an astronomically low value at high energies doesn't concern Sabine. She's fine with having parameters be set to peculiarly low values without any explanation for why they're small. Also no mention the running of the higgs lambda parameter which also makes it very likely that there's new physics that the higgs is involved in.
Also if you're fine with setting a parameter to be remarkably small without any explanation for why it's small, then neutrino masses aren't a problem. Neutrinos just have a right handed component and they happen to have very small coupling to the higgs. But Sabine has no problem with Majorana neutrinos - a theory motivated to explain why neutrino masses are so small. Probably because it isn't a collider experiment.
Dark matter could be particles or MOND, but because there's another possibility, we shouldn't look for particle dark matter.
Antimmater asymmetry might just be an initial condition (it might not be, but we shouldn't investigate CP violation because it's possible that hypothesis might be wrong)
It all kind of feels like an argument in the form "we should just stop trying to find new physics. We should close our eyes and say that's just how it is." What if there are explanations for some of these things? What if the aesthetic arguments about the higgs mass are right and there's new physics that explains the higgs mass. What if the early universe had equal amounts of antimatter and matter as most physicists think "seems nice" and then there's an explanation for how that symmetry breaks? If we follow Sabine's advice, we would just stop knowing physics and never know these things.
I think we should investigate all possibilities, especially ones that our aesthetic sense tells us are likely. We should investigate mond and particle dark matter. We should build new colliders to see if there's new physics. We should see if there's an explanation for the higgs mass, knowing that there might not be any explanation. Sure, we aren't 100% certain that a new collider will tell us something new. We aren't 100% sure it won't though. Sabine seems to imply that because it's possible there's no more explanations out there, we should assume there absolutely aren't any more explanations out there and we should accept the models that explain our mysteries in terms of arbitarily chosen constants (arbitrarily chosen constants that really make it look ljike there's a deeper structure)
Well said!
One correction
Dark energy is controversial. Because we aren't even sure whether universe expansion is accelerating or not. As we look for more data with Euclid then we can say for new physics or not
Sabine, you are my Ricky Gervais of particle physics! Your kind of black humor is ultimately hilarious... but I know you only tell the truth, but in a way Ricky couldn't do it any better. Thanks so much for all your awesomeness and work!!!
Thank you for explaining what the hell is going on in particle physics.👍🏽
Love your videos. We need new physics though, and we will have it!
Supersymmetry, hell! I'm still looking for magnetic monopoles!
A team from Cornell had proposed in a paper that gravity was part of the EM spectrum. The paper was retracted shortly after but ... many years later, gravity waves are discovered. Is it time to reconsider gravity as part of EM? Would a quantum gravity theory have a problem with that?
I love Sabine's no-nonsense and clear explanations of complex physics and mathematics. Science without the gobbledygook indeed. Bravo Sabine, please keep them coming!
I really hope all those physicists you keep trashing take it in good humor. There's nothing wrong with looking for a way to keep justifying your paycheck, but professional integrity is also important and I'm glad controversial people like you exist to shake things up every once in a while and force physicists to hold their beliefs to more scrutiny.
They do not. Sabine is pretty poorly regarded in the particle physics community. Astrophysicists are pretty neutral on her takes however.
As a particle physicist working at a big collider experiment, I can confirm that I do not appreciate Sabine's takes.
Her arguments on the physics are comletely valid, but the general picture she draws of particle physicists is not justified from my experience. From her video you get the impression that particle physicists almost blindly believe theories you present them without thought. In reality, all arguments she talks about here are discussed (at much much more depth) amongst experimental particle physicists. Building new colliders is also controversial amongst us.
It's sad that she has to mix an interesting physics topics with politics, and discrediting her collegues to make it controvertial.
@@Andy-qn7py Yet, as much as you don't appreciate her takes, you take time to comment on her videos, which in the internet world means you're effectively supporting her work.
And see, that's what I mean by taking it in good humor. As much as I understand what you explain about reality being more nuanced than a popular UA-cam video (spoiler alert: it always is, and if you don't like it then you're disliking the system, not the people in it), you should be able to accept that her criticism is at least somewhat valid and that her intention is not to mock particle physicists but rather make everyone hold them to a higher professional integrity standard. That's the function controversial figures should be serving ideally, and you can appreciate it even if you don't like it.
@@ObjectsInMotion well, we live in a culture that glorifies being offended so it's not surprising. I think history will be on her side though eventually... And if not she'll always have her adoptive UA-cam family ;)
@@ronigbzjr I don't mind supporting her work, she makes great content in general, that doesn't mean it can't be criticised.
I don't see how the fact that everybody makes artificially controversial content justifies her doing it.
WE NEED new physics because what we have doesn't readily lend itself to granting our sci-fi fantasies. Until you guys give us FTL ships, anti-gravity everything, mass teleportation and free energy. It's not good enough guys.
Tongue in cheek but there's truth in that. The widening gap between sci and fi unaccompanied by a growing societal appreciation for the tangible fruits of evidence-based science is a valid concern imo.
I'd call that a want, not a need. What we need is more rational education.
@@Llortnerof No, we need. Because of that education. If we have to concede in the end that we are stuck on this planet, that there's nothing more to explore, nothing more to find out, than it's game over, and humanity will decend into a real dark age, with everyone only looking after the short term gain, and **** the future - because everything that was, is or will be done is futile, meaning- and useless anyway.
Why do you think birth rates in the highly educated, industrialised countries are dropping? Just because people don't like children any more, and have become so selfish that they do not want to look after their own children but rather party 2,5 days of the week? Maybe, for some part, yes.
But I have the suspicion, that deep inside, they're already feeling it, and now that they turned away from the thing that was invented to fight this by giving them a false sense of duty(religion), they have the growing nagging suspicion, that everyhing is meaningless.
You. Me. The Universe - meaningless.
Conversely, does that mean those physicists are looking for God? In a way, yes - a god not associated with (a specific) religion, but with the laws of nature, expressed as mathematics. (Search for "The Word of God ©1994 by Catherine Faber")
@@memyshelfandeye318 Because having children in those countries is f-ing expensive, that's why. And not just the direct costs, either.
It's really not that deep. Meaning is something you make for yourself anyway.
Love the underlying sarcasm and dry sense of humor. 🔥
We need a particle collider on the scale of the Solar system. Those meager 100 km are way too small.
It’s refreshing to watch a video that doesn’t just cover a subject, but actually makes a statement!
Great video, great physicist, strong message thank you
Very strong message. At the same time, I wonder how many physicists go down this route simply to pay their bills - and how sad that reality is.
Many thanks from the entire team!
Quick fact: the guy who died at an MRI exam for having a gun was accompanying his mom and she was doing the exam, he violated the "no metals in the room/body rule" and although he removed the magazine there was still a bullet in the chamber which he didn't remove. The MRI machine unlocked the pistol and pulled the trigger. Ironically, he was also a huge pro-weapons guy, so there's that.
as a gun nut myself i find this tragic for his mother and the staff they didn't deserve to see that and live with it. The guy on the other hand should've known that could have happened. I will never understand some of my fellow gun owners who simultaneously agree guns are extremely dangerous and worth having yet ignore their own basic gun safety. Dumbass got a darwin award for sure.
Oh, now I understand. There's no way the patient wouldn't have been told to leave the metals in the locker.

I remember coming across a fascinating case involving the detection of a potential variation in the speed of light. But, intriguingly, this didn't lead to a questioning of the theory of relativity. Instead, an innovative approach was taken: redefining how we measure the speed of light. The idea was to base the measurement on the time it takes for light to travel a certain distance. This clever move effectively rendered the speed of light a constant, impervious to any fluctuations.
All I'll say it's since I started watching Sabine's videos I can see more clearly that not only tabloid press create misguiding/too promising/excessively optimistic articles but also prestigious and kind of trust-worthy sites such as quanta magazine and the bbc news.
So from that moment on, I carefully analyse and add an ounce of skepticism to what I read on such sciency/popular science websites.
Love the checklist of physics open questions.
As a non-scientist my best armchair guess is the best route to discovering new physics is be the next generation of telescopes able to probe the universe in greater detail. Hopefully I'll live long enough to learn some of the answers.
The latest space telescope project already basically proved big-bang and most of cosmology to be utterly wrong AGAIN. I wonder what they make up this time?
@@rosomak8244 lol no it didn't
@@rosomak8244 You don't expect something new do you? They will just say the Big Bang is still right. Perhaps you are referring to the group that went through JWST survey data looking for the most distant galaxies. Right after that paper came out Dr Becky did a video on the assumptions, models, and estimates they used. JWST did not measure the redshifts of those objects, but the authors estimated them. The next step is not to throw out the Big Bang Model, but to get time on some telescope, take the spectrum of those objects, and MEASURE their redshifts rather than estimating them. Confirm or deny the estimates.
Also, those might not even be galaxies. NdG Tyson just did a video (the one where the thumbnail asks if we are living inside a black hole) where his expert suggests that they might be jets produced by black holes. And we are in the paths of those jets. Brightness was used to estimate the size, and thus the age, of those galaxies. Instead of the brightness going evenly in all directions, we might be in the path of a bright jet, so the objects were dimmer, smaller, and younger than the paper estimated. Of course, you should not accept either theory until further measurements can be carried out. You did not think that a preliminary result could be published and all physicists would hang their heads in shame that they had ever believed the Big Bang?
You don't have to force yourself to live longer for such an insignificant reason! Have a normal life, but be Happy! - There is one book, which has answers to all these "Puzzles" Its title is - "Theory of Everything in Physics and the Universe"
Yet another brilliant episode from Sabine. I tell you. Sabine is practical to the point of genius.
I strongly disagree. I was laughing so hard when she talked about other physicists "making things up". That is exactly what she does. Some of her videos are evidence based and others are not. Sometimes she just puts out her ideas without any evidence to back up her claims.
@@mikemccormick6128YOUR evidence? Looked many of her videos and never found, what you claim. If there is no evidence in her videos, she always makes clear, that it´s her opinion or just speculation. You have to hear exactly, what she says.
@@Thomas-gk42 I don't recall hearing any evidence about how we can't make our own decisions because free will does not exist. I believe she comes to that conclusion because there is an Uncertainty Principal in Quantum Mechanics and the fact that a particle can be in two places at the same time. But the laws of the quantum world don't necessarily apply to our world. They are two separate realms.
@@mikemccormick6128 ok, you´re fixed on her statements about free will?
First, this is a mathematical statement based on the fact, that our world is causal dependent organized, even in the chaos research. In QM, you spoke about, she prefers superdeterminism, a possibility, to solve the measurement problem. It´s not more deterministic, as classical physics, but You should read her new book (Existential Physicis) where she phylosophically/psychologically gives a lot of place for free will, for everyone who needs it.
@@Thomas-gk42 She doesn't believe the 2nd law of thermodynamics. I would say that the vast majority of physicists believe the 2nd law of thermodynamics.
I always love when Sabine says "that's what we will talk about today"
Ha, it's like a little sun beam. 😁
18:08 - At first I heard that as "you're watching the Beanus channel" and I thought "well, Mr. Biffo is looking very different today".
I just recently "learned" that the Higgs Mechanism is not the sole source of mass in the universe. The bulk of the mass in the universe is the energy manifested in the strong nuclear force. I had forgotten that mass = energy. How is it that the strong nuclear force gives the universe more mass than the Higgs Mechanism. I am not convinced that this is true, but am reminded that the majority of energy in a fast fission device comes from the strong nuclear force giving up the energy it uses to hold nucleons together.
