Hi Sabine, I finally did a few basic sums and found my model adds up pretty well. More than a coincidence?! Only core particle mass is really significant in my 'model' where a Muon is a strongly bonded electron+positron (2 core particles) + non strongly bonded electron.. A Proton is 2 positrons strongly bonded to 1 electron (3 core particles).. a Tau is 2 positrons strongly bonded to 2 electrons (4 core particles) + non strongly bonded electron.. So: Tau Mass (more or less) = Proton Mass + (Proton Mass - Muon Mass), or it should in this model at least... 938+(938-105)=1771... Tau Mass is about 1776 MeV.. -- 938.27+(938.27-105.66)=1770.88... If you use the mass difference between neutron (proton + electron in this model) and proton (939.56-938.27=1.29) as a guide for what the spare electron does for a muon and tau compared to a proton you could do: 105.66-1.29=104.37 muon 'core mass'... 1776.86-1.29=1775.57 tau core mass... 938.27+(938.27-104.37)=1772.17 predicted tau core mass.. There must be another factor.. Also, I am using the Strong Force differently here. It should be called the 'Heavy Force'! -- When Taus and Muons slow from (near) light speed due to interaction with matter the electrons and positrons annihilate, leaving the spare electron. Also, the mass multiplier mechanism that makes 'heavily bonded' core electrons and positrons so much more massive than when free only kicks in when the tau or muon slows from (near) light speed while a proton's mass is permanent and travels with it.
No it’s not working the science doesn’t understand 95% of the university and that’s dark matter and energy Also the universe is now 26.7 billion years so all the books must be crossed out! - the same when the wind blows 😮
"..in which muons go in circles until they decay, which is a good metaphor for life in general." I am a fan of Sabine's dry humor. Great observation too.
"Scientist say the sun is brighter than we thought." Now I'm just imagining a scientist staring directly at the sun and going: _"Ow, Jesus!_ That's _way_ brighter than I thought it would be!"
What often amazes me about Sabine is, as a physicist, she makes predictions based on her observations and experimental data, and it's shocking how often her predictions are right. She predicts "...and, of course, the phone will ring." And she's RIGHT. EVERY. GODDAMN. TIME. Quantum physics just blows my mind.
It's like the thing with your keys. They're always in the place where you look last. Although, I dare you to keep looking just in case that observation might be wrong.
Sabine, the SpaceX test was a success. Everything that happened after liftoff was a bonus. Everything did work out as planned, plus we discovered a few things we need to look at
@@itemushmush are you an engineer? Do you understand testing? The test objective was takeoff capability. That was a success. Everything after that was basically free data for flight systems, with the bonus that they got to test the self destruct function too. From a test perspective, it was a fantastic success.
SpaceX repeatedly stated this in the weeks leading up to the launch. The goal was to test out the ground equipment and prove they could get off the pad.
Two interesting things - with regard to space hotels, there was a Hilton Hotel on the space station in '2001 : A Space Odyssey' - Heywood Floyd sits in its 'lobby' on those big red chairs while keeping his mission secret to visiting Russian scientists. And Buzz Aldrin did take wine to the moon, in the form of a consecrated vial of communion wine and bread wafer - this is seen in the HBO TV miniseries 'From the Earth to the Moon'.
I remember reading about ISS when I was an 8-year-old child in 2000. I remember how amazing it felt reading about it. It feels sad as I am 31 to hear the station will be decommissioned soon.
It is a truly horrific act that such a precious historical artifact will not be preserved and will instead be thrown at the planet to 'hopefully' destroy it. Like burning down an ancient library "because it's just so difficult to keep it clean".
@@Tao_Tology They either have to constantly fuel it or destroy it, just letting it orbit on it's own is dangerous cause it'll eventually fall, and you won't be able to control where
@@rizizum Or......Langrange points. A literal 'holding space' and the earth has 4 to choose from. Really, the destruction of the ISS is a historical and cultural loss.
@@Someone-tn8ur Given that it won't be occupied it doesn't need 'human survival' systems on board. It is, though, a unique technological achievement and unarguably something that would be valued by future generations (even if the bean counters at NASA can't look beyond it's immediate value).
15:00 A little more context would be appreciated here, especially given the amount of misinformation purposefully spread by Elon / Space exploration haters. That was a very experimental test, they knew that a rapid unplanned dissasembly was the most likely scenario, and the design had already advanced past the ship that was used. They were happy the ship even took off. That """failure""" should not be taken as the cause of any delays, if they exist.
Muons going around rings of magnet until they decay being a metaphor for life on general is an underrated joke! I spat my morning coffee out. I love such kind of deadpan/dark jokes.
In regard to the moon landing, it's not just SpaceX that is holding them back. SpaceX will probably be ready before anyone else for this mission. They still don't even have a space suit or are close to even finishing a prototype that works. Artemis 3 is not even built and the gateway space station which is required for docking and transferring astronauts is not even built. SpaceX is just a political scapegoat. There is a bigger chance of SpaceX landing people than Nasa themselves. There is a big fear in the space industry. SpaceX is set to dominate even more than it is now and there is nothing anyone is willing to do anything about it because all the other companies have shareholders to satisfy and taking risks is a no no.
The news is great, and delivered as only Sabine can with no gibberish, but it's the comedy that keeps me coming back. So many physics jokes... she's catnip for geeks
It's raining here, I don't see a sun and frankly I'm skeptical if it even exists. You say you went blind as evidence but any number of things can make you go blind, I'll need something more compelling if you expect me to believe this "giant fireball suspended in the sky" theory
This type of videos in which you explain new findings of science to common folks are absolutely amazing....I don't know of any other such type of source
Blaming Starship is just NASA's way of obscuring the fact that they are not ready for a planned Artemis 3 landing date either. I watched this game get played for every big project there for ten years. Everybody is running late but nobody will admit it in the hopes that someone else will have to and become the scapegoat that relieves the pressure on everyone. If the first test flight had gone perfectly, they would have found someone else to blame.
We need some forensic accountants to go over the artemis program and some executives need to lose their jobs for letting corruption kneecap our chance at the moon. Scapegoating SpaceX for following SpaceX's typical engineering prototyping strategy is just criminal.
4:15 I forget the origin of the theory, but I remember speculation that the sun's output of high energy particles has increased significantly. The speculation was that this contributed to global warming - as while our atmosphere and magnetosphere stop these particles from reaching the ground, it does so by absorbing their energy. This was not framed in terms of being dismissive of climate change, but rather that reducing carbon dioxide & other greenhouse gas levels is even more important, as previous models took the sun's output to be constant. If that's not the case, well, even a tiny increase in solar output can have drastic consequences. That makes our efforts more important than ever.
That prototype of Starship was not expected to reach space. The main successful outcome of the test was for Starship to lift off and get away from the launch facility which it did, although not really with expectations. The biggest failure though was the flight termination system took to long to rip open the tanks as they misjudge what it would take to rip those tanks apart. Even now, Elon Musk has stated he thinks the second test flight only has a 50/50 chance to reach orbit. These test flights goals in the early stages test not just the rockets ability to get to orbit but to test things like correlation for data for Max Dynamic Pressure, Aerodynamic Flight (although first starship flew even with outdated flap designs), now Hot Staging, etc. I'm confused how people still don't understand that SpaceX has a different way of testing rockets than other companies even though it has been stated hundreds of times by SpaceX and all of Starbase watcher youtubers that put out better news videos than 99% of the news agencies in the world. The delays in the Starship lander are more likely due to environmental agencies pushing back, possible legal battles with jealous competitors, etc. Not due to what the media considers a test flight failure when SpaceX considered it a success for what the test flight was meant to achieve.
I probably misunderstood what I was reading, but …if mass gets added only when a certain type of weird particle is added ( I’m feeling dizzy already!) then it occurs to me to ask when/how does time get added? That is, given time seems to be a “plug” in the equation, when you start backing out the speeds of the guys with the flashlights - one on the train and the other standing still, and we’re holding the speed of light constant, …is there a thing that adds time to go with the mass? Light is constant… Photons have no mass but they move and oscillate… Space-time is lumpy… What, then, is giving us this mirage of time? Or maybe I’m asking what gives us this mirage of distance, within which we keep trying to impute a concept of time? What exactly is “time?” Or I guess in the phrase, “spooky action at a distance,” is there a way to treat that distance like constant and plug something else we’ve always assumed was deterministic? Help! I’ve fallen and I can’t get up! I absolutely ❤ this channel! I knew you called it right on the LK-99. You have a knack for yes! Removing the gobbledygook! 🎉
I'm new to this channel! Professor Moriarty (Sixty Symbols, not Sherlock Holmes archnemesis) mentioned Sabine in a recent video and I decided to stop by. I'm glad I've got this great source of science new now. Thanks for your hard work!
A few days ago I posted a question. This question is sort of a follow on... I assume ask my questions are too basic to be real questions, but rather are kind of study notes as I try to work through the subject matter. In that ... light... here's my current progress and my next questions... Based on the video linked below, I have this bit -- if observations of electromagnetic energy give us the illusion of spacetime, and entropy is something like the same kind of illusion for quantum mechanics, and electrons have this weird "demon" state (when they aren't turning into anti-electrons?), then don't we need to suppose an on-off switch for "existence" as part of existence? I mean, quantum entanglement only looks like that because during part of the experiment some of the particles were "off" and then came back "on"? The observer would assume "time passed" and "distance was traveled" but really it was just a state change to "off" and then to "on" for existence ...of the entangled ... um... information? If, as in the end of this video, existence is kind of a crunchy quantum sand, then we just need to describe the sand when it's "off" right? It would be fun to make that description consistent with dark matter. Right? So what is that then? What's the current thinking on unobservable states that blink on and off at different readings in spacetime? I'm feeling very dizzy. Here's the video I that's got me trying again to form a coherent question about gobbledygook! Keep doing your amazing awesome work! My kids and I are enjoying the hell outta this! (Well, I am!) ua-cam.com/video/yPVQtvbiS4Y/v-deo.html
It isn't so much that things come into existence as that energy changes shape, so to speak. One collection of particles can change into another collection of particles, thank to quantum mechanics, provided that all conservation laws are concerned. It doesn't help with dark matter exactly because energy is conserved. You can't just make matter out of nothing.
@@SabineHossenfelder I forgot about conservation, believe it or not. 🤦♂️ But when I was saying "off/on" I meant observable / not observable. I'm feeling like there is a presumption that time is passing built into the explanations of light having a finite speed, stuff we measure using light, and ideas like the expansion of the universe. Obviously this stuff is beyond me, but it's fun to try. But spacetime is one word now. So I'm ...my brain can't hang on long enough to walk this thought all the way through. A singularity requires dividing by zero. Something ain't quite right! Then again, I am just now trying to understand the Higgs field. Also, I keep trying to imagine a "field" as something akin to a sheet of vibrating plastic wrap in space, rather than as "any equation that makes good predictions." Keep going! We need you!♥️
I would be concerned about the 'Space Wine', after all, there is a saying onboard the ISS "today's coffee is tomorrow's coffee", maybe the same goes for the wine.
"Plasmarize" is almost non-existent. "Plasmatize" (with a 't' for the 'r') is about twelve times as common, and is better formed, etymologically speaking.
In case nobody has mentioned it, I want you to know I >really< appreciate your sense of humor - not a character trait one typically expects in the serious sciences.
@@retiredbore378 I once had a biochemist friend, with whom I sang in church choir and played Pinochle with every week, who was barking mad! (A good sense of humor.) He was a biochemistry professor at the Ohio State University and had a strange connection with some guy he introduced as Basil, who was apparently connected in some way with discovering the steroid involved the birth control pill. (He was a real globetrotter) Dirty jokes abounded! LOL! I lost track of him when I moved away. He's probably dead by now. Someone I treasure having known in this life, no matter how ever so briefly.
RC delay from interconnects is roughly the same as transistor switching speeds and are a significant drag on chip performance. The focus has been mainly on the C side using low-k dielectrics. A zero resistance interconnect would be a great leap. It would also make you rich. 😊
Only if you work for yourself in an politico-economic system allowing you to retain the fruits of your labor. In the West, we generally have patent laws to encourage inventions to be shared with the world while allowing the inventors to have economic gains. It's why almost all modern nice things come from the West. Of course, many countries of Asia, Middle East, and Africa flock with Russia for Russia's modern nice things and Red China's complaining of the U. S. A. stopping its rise because it's getting more difficult to stand on its own two feet without copying the West.
On one hand it's a pity that international collaboration for space stations degreses. On the other hand, it's nice to see humanity got more sciencey artificial real estate at least in LEO
I’m no physicist, but your videos make me feel like one! Hey might up and down quarks be the equivalent of the peak and the trough of a wave? I’m sure that’s been debated, but I’d love your take on that rabbit hole. I’m trying to think: if the peaks of waves happen to coincide, that’s the kind of thing that would spike up enough energy to make a state change to matter, right? Or mass? And in radio, you have carrier waves that😵💫 kinda ride along on the main wave? The weak force strikes me some kind of background noise that, if we had a model, might be just enough “carrier wave” to “pay for” that state change? The gap I have never understood is this: through what medium are all these waves oscillating? I end up thinking of a field as a medium, like a fluid. I assume I’ve lost track of conservation of energy now. But it feels like we need to reframe quantum stuff in terms of turbulence and then speculate about why we can’t detect the medium more easily. If we can’t measure something, but we can see an effect, isn’t that a dead give away that we need to get outside the model we have? I’m trying to imagine Newton seeing a cannon ball and the moon as equivalent, though that violated a lot of contemporary assumptions. Where’s the pervasive medium for all these waves? Can we “see” it at absolute zero or something? What would it look like if the medium was, uh, “dried up” at some spot? Is that the evaporation at the end of a black hole, or max entropy, or like a primitive, “…where’d it go?!” On the other hand, what if there was a tsunami one day? Fluid mechanics gets described by chaos and fractals I guess. Why don’t I see more comparisons to fluids as an analogy for the noise in subatomic physics? We have the wave idea. What happened to the medium? Like why isn’t the transition from “energy“ to mass-bearing particles similar, say, to the disruption of laminar flow at the leading edge of the wing of a supersonic jet? Obviously, whatever that state change is, it can cascade…(fission) …so what’s the “water” doing just before it evaporates? If you go faster than light do you spontaneously become matter? Is gravity the effect of matter trying to “cool off” back to energy? Is that why time is a weird idea? You can only tell time by noticing changes in the height of these waves, or…what? Please discuss…?
😂 1:45 “…in which the muons go in circles until they decay, which is a good metaphor for life in general.” - 🤣🤣 The subtle Sabine humour/sarcasm already within the 2nd minute. What a start.
If they de-orbit the ISS by 2031, are they going to do it the same way the Chinese do it, i.e. by just letting nature (i.e. gravity) take its course, so that it falls randomly on the part of Planet Earth which happens to be the most unlucky at the time? Perhaps it will fall on Tien An Men Square? The Chinese would like that.
Correction: the Starship test flight did not fail to separate. It did not get that far in the timeline and the separation was not attempted before the flight was terminated.
Multiple engine failures among other problems ended it early. It’s most impressive feat was spinning out of control at peak atmospheric drag forces and remaining in one piece.
I watch your videos bevause my Dad, who did some work on early radar, and even met Alan Turing, got me interested in science because he used to bring home New Scientist from thePayment office. Thanks for your upload
I wonder do those gamma rays effect the wine in space? Great video Sabine. Nice getting info that's light and humorous. Yet also demystifies some of these ideas that are way out of my scope of knowledge.
13:49 This animation where the moon goes aroung the earth, in the WRONG direction and also SPINING is infuriating! whaaaaaaaaa, Dr.Hossenfelder, how could you pick it.
In fact, every goal SpaceX had for the "4/20" launch was met or exceeded. The wish, to actually achieve orbit, was just that. The requirement, to gather useful design and performance data while developing/refining flight procedures for such a bird, was not only met. In the time since the OLM has been re-designed, re-built, radically enhanced and tested. Staging has been re-designed and a test article "can-crush" tested. Some hot-stage article will soon be installed on a modified B9 (it looks like). And as Musk said, a couple more meters of det-cord is all the self-destruct needs. NASA never has and never will move like that. Politics don't permit it.
@@ShotgunAFlyboy Exactly. If the politically-motivated haters can be kept at bay, Starship will be operational next year and will fly just like Falcon 9. I mean, look how much when wrong on 4/20, and it still ascended. That stainless bird could just be a beast.
15:02 the spaceX insisted that the goal for that starship test was to simply pass the launch towers. It met that goal, no? How come that starship test is related to a delay for Artemis?
Its definatly not causing a delay yet and the test is not a cause for concern. I suspect Starship will be ready for 2025 but Artemis won't. But there is a lot still to do for starship to be ready. They will have to land on the moon at least once before NASA will certfy it for people. That means they will need to make a new or servearl new launch towers as they can't launch from Boca as there launch licence prevents them. They also still need to do in space refuling, somthing that has never been done before. Dear moon will happen first for sure. I hopeing for late 2025 but wont be suprised if that slips a couple years who knows!
@@R0nBurgundythat is very reasonable but I think the video was (unintentionally, I’m sure) misleading in directly pinning the delay of Artemis to Starship’s integrated test, see 14:45. It is also factually incorrect in saying the test did not work out as planned. As a proud patreon and long-time viewer, this is a bit disappointing.
Seems like politicians are trying to throw SpaceX under the bus to cover for corruption in some of the other vendors that fell behind on Artemis. We all saw how many times A1 had to scrub. It got pathetic watching several Falcon 9's and a Falcon Heavy launch in the time that A1 kept scrubbing and scrubbing and scrubbing.
i'm in my late 30s. one of my favorite shows as a kid in the early 90s was "beyond 2000" on the discovery channel here in the states. (RIP "discovery" channel and the "learning" channel) your YT comes as close as any to sharing the same spirit as that show - showing and telling about what's to come.
15:00 - inaccurate: - the whole development is slower than expected - not just one test showing problems - it didn't "fail to separate" - it never reached altitude for separation - that was due to engine failures (some engines failed to begin with, and more likely caused by debris from obliterated concrete under launch pad ; it was so powerful, it compressed the earth, "snapped" the protective heat resistant concrete and shattered the whole thing from the inside (most likely) digging a huge crater) - the test itself was not "planned" to reach any point, and apart from that, the vehicle performed "better" than they expected (well, it was a test to find out - they did not know) - Also, there were issues with detonating it, as it was sturdier than expected. - (That was probably the biggest "safety issue" - my opinion, as if it veered off course, it would not be destroyed in time. But, it's an easy to solve issue once known.) - so, is the situation better or worse? I don't know. I'm just correcting small details in this video. - The overall message is correct: it's taking longer than Elon hoped ... but that's true for most projects and companies; Elon especially has very optimistic expectations...
Perhaps this isn't a fifth force, but a detection of what gravity really is. As EM waves pass through sub atomic particles they change their position slightly to maximize attractive force and minimize repulsive force, resulting in a tiny net positive.
10:31 considering its the airforce i assume they need it to condense propellant for a plane so it takes less space or to cool the surfaces of a really fast aircraft (probably the sr-72 darkstar program which will probably be flying at 8 Mach which would be why it would need cooling, especially if its got the same radar absorbing materials as the b-21)
Honestly, Artemis has been going way too smoothly, I'm glad they found some issues before getting to manned missions. The timeline was ambitious to begin with.
to smoothly? What planet are you from. Artemus was suppose to launch in 2017? Then 2019 then 2020 then 2021 then 2022. Do you forget the Boeing debacle, of the core stage, ML fiasco and VAB over budget issues, This program has been a mess...
Well it is a bit ambitious to slot in a criticality one subsystem that is a lunatic (pun inpunded). Muskus might deliver you a landing craft. He might deliver you a space toboggan. He might discern that Mars is in fact the actual god of war and retask his space division to produce grappling hooks to enable a landing crew to take a celestial body by force. Ok Diana, hunt THIS.
Artemis is a welfare program for the usual MIC contractors. SLS is a complete waste of money and using solid boosters is dangerous for human launches. Just let SpaceX do it on private sector money!
Also worth remembering not to discount a weak force because it's weak. The Weak Force itself essentially does nothing, but it's crucial for how the world works under the right conditions
It is interesting to see how the elemental factors which interconnect to create their resonance with each other are continuously being discovered and redefined.
@@buddygrimfield7954 Try to see how your statement is so vague as to be almost meaningless. Elementary aspects of physics are not being continuously discovered; it happens fairly suddenly only every so often. The last major theoretical discovery I can think of is the Higgs boson in around 1962. (It can be said to be discovered then, even though it was not observed until around 10 years ago, because it is necessary for the standard model to be considered valid-which it is, even if it is not complete.
I can see how I could have worded my (uneducated) opinion regarding my interest in how the interconnecting relationship between the known physical forces are continually being redefined a bit better than I did. But it was merely a casual comment. So, if it offended you so badly that you feel the need to "correct" me about it, perhaps you have far bigger issues than my casual comment being "almost meaningless" as you put it. Anyway, have a nice day. And I hope that works out for you.
I remember see a headline "Sabine Hossenfelder was wrong about LK99". She should have waited a couple days to see the new results (i.e. twitter videos), before making her first video mentioning it! Yeah that aged like fine milk 🤣🤣🤣
@@chicojcf Please take a look at the graph Sabine provides, with its scale of energy to the left. It's a logarithmic scale. The intensity of radiation in the gamma-ray spectrum is at least three orders of magnitude less than the intensity in the visible.

Some of these concepts are out of my wheelhouse, so it's good to learn more about them ❤ ... Is the moon supposed to be spinning at timestamp 13:40 ? I'd always thought the moon was tidal locked. This animation had me stop to rewind
It looks like not all of the water around Greenland is getting cooler, only the portion below, so i don’t think that would be the best explanation. The coldest spot also appears to be quite far away from Greenland on a global scale, and incredibly massive. We would also expect to see cooling around the other melting glaciers around the Earth, so this blob seems to be a far greater cooling effect then just cold water being introduced to the oceans
Time to dredge up a joke from the eighties: "Yes, they've found a fifth force. However, they've also found a sixth force which exactly cancels it out."
I think half because: the methods that most of this research employ is often new and unique. It can require some extra watching even for a scientist. The other half because Sabine goes through it quite quickly and lets not forget this basis of science that we keep building up, is built on many hundreds of years of intensive research. You basically get only some flavors even with a scientific study.
Amazing how many people dissed Sabine for saying that LK99 was probably like the other room temperature superconductors, fake. Time for them to fess up and apologise! Do I see a flying pig
I'm glad Brookhaven found my muon g -2s and their deviations from those predicted by the standard model. I've been going up the GD walls looking for those things, now I remember leaving them there.

Saying that the first Starship "did not go as planned" is a bit misleading. Yes, the Starship did not make it to orbit but that was not the primary goal of the mission. The main goal of the launch was to gather data and not blow up on the pad. It did do that. Also the mission disposed of some materials they no longer need to store and it also "helped" with the pad excavation work SpaceX had planned. Come to think of it, maybe based on this new technique, Elon should add Raptor engines to the front of his tunnel boring machine.

Hi Sabine, I finally did a few basic sums and found my model adds up pretty well. More than a coincidence?! Only core particle mass is really significant in my 'model' where a Muon is a strongly bonded electron+positron (2 core particles) + non strongly bonded electron.. A Proton is 2 positrons strongly bonded to 1 electron (3 core particles).. a Tau is 2 positrons strongly bonded to 2 electrons (4 core particles) + non strongly bonded electron.. So: Tau Mass (more or less) = Proton Mass + (Proton Mass - Muon Mass), or it should in this model at least... 938+(938-105)=1771... Tau Mass is about 1776 MeV..
--
938.27+(938.27-105.66)=1770.88... If you use the mass difference between neutron (proton + electron in this model) and proton (939.56-938.27=1.29) as a guide for what the spare electron does for a muon and tau compared to a proton you could do: 105.66-1.29=104.37 muon 'core mass'... 1776.86-1.29=1775.57 tau core mass... 938.27+(938.27-104.37)=1772.17 predicted tau core mass.. There must be another factor.. Also, I am using the Strong Force differently here. It should be called the 'Heavy Force'!
--
When Taus and Muons slow from (near) light speed due to interaction with matter the electrons and positrons annihilate, leaving the spare electron. Also, the mass multiplier mechanism that makes 'heavily bonded' core electrons and positrons so much more massive than when free only kicks in when the tau or muon slows from (near) light speed while a proton's mass is permanent and travels with it.
The best takeaway from LK99 is that real science is still working as intended. In this day and age, that is encouraging. 👍🏻
of course it is, only a fringe group of "heterodox outsiders" whose business model is to claim there is some kind of crisis is claiming otherwise.
No it’s not working the science doesn’t understand 95% of the university and that’s dark matter and energy Also the universe is now 26.7 billion years so all the books must be crossed out! - the same when the wind blows 😮
LK99 have some interesting properties. Science cannot denied such achievement.
Probably with some tweaks, those properties can be increased.
@sccp1997 it can be denied, since the properties have been recreated a bunch now and appear to be quite benign. What is there to tweak and improve?
@@ravener96 some scientist are experimenting different tweaks which they believe can give some superconductivity

What often amazes me about Sabine is, as a physicist, she makes predictions based on her observations and experimental data, and it's shocking how often her predictions are right. She predicts "...and, of course, the phone will ring." And she's RIGHT. EVERY. GODDAMN. TIME. Quantum physics just blows my mind.
It's like the thing with your keys. They're always in the place where you look last. Although, I dare you to keep looking just in case that observation might be wrong.
Actually, what I like about that lady Sabine is that she often does talk about subjects that is based on sociology and psychology
Sabine, the SpaceX test was a success. Everything that happened after liftoff was a bonus. Everything did work out as planned, plus we discovered a few things we need to look at
pure copium lol. who on earth would class it as a success when it needed to be BLOWN UP???
@@itemushmush are you an engineer? Do you understand testing? The test objective was takeoff capability. That was a success. Everything after that was basically free data for flight systems, with the bonus that they got to test the self destruct function too. From a test perspective, it was a fantastic success.
@@itemushmush Smooth brain take. SpaceX blew up lots of Falcon 9's before they ever put customer payloads on them.
SpaceX repeatedly stated this in the weeks leading up to the launch. The goal was to test out the ground equipment and prove they could get off the pad.
Two interesting things - with regard to space hotels, there was a Hilton Hotel on the space station in '2001 : A Space Odyssey' - Heywood Floyd sits in its 'lobby' on those big red chairs while keeping his mission secret to visiting Russian scientists.
And Buzz Aldrin did take wine to the moon, in the form of a consecrated vial of communion wine and bread wafer - this is seen in the HBO TV miniseries 'From the Earth to the Moon'.

15:00 A little more context would be appreciated here, especially given the amount of misinformation purposefully spread by Elon / Space exploration haters. That was a very experimental test, they knew that a rapid unplanned dissasembly was the most likely scenario, and the design had already advanced past the ship that was used. They were happy the ship even took off. That """failure""" should not be taken as the cause of any delays, if they exist.
Muons going around rings of magnet until they decay being a metaphor for life on general is an underrated joke! I spat my morning coffee out. I love such kind of deadpan/dark jokes.

In regard to the moon landing, it's not just SpaceX that is holding them back. SpaceX will probably be ready before anyone else for this mission. They still don't even have a space suit or are close to even finishing a prototype that works. Artemis 3 is not even built and the gateway space station which is required for docking and transferring astronauts is not even built. SpaceX is just a political scapegoat. There is a bigger chance of SpaceX landing people than Nasa themselves. There is a big fear in the space industry. SpaceX is set to dominate even more than it is now and there is nothing anyone is willing to do anything about it because all the other companies have shareholders to satisfy and taking risks is a no no.

Blaming Starship is just NASA's way of obscuring the fact that they are not ready for a planned Artemis 3 landing date either. I watched this game get played for every big project there for ten years. Everybody is running late but nobody will admit it in the hopes that someone else will have to and become the scapegoat that relieves the pressure on everyone. If the first test flight had gone perfectly, they would have found someone else to blame.
We need some forensic accountants to go over the artemis program and some executives need to lose their jobs for letting corruption kneecap our chance at the moon. Scapegoating SpaceX for following SpaceX's typical engineering prototyping strategy is just criminal.
4:15 I forget the origin of the theory, but I remember speculation that the sun's output of high energy particles has increased significantly. The speculation was that this contributed to global warming - as while our atmosphere and magnetosphere stop these particles from reaching the ground, it does so by absorbing their energy.
This was not framed in terms of being dismissive of climate change, but rather that reducing carbon dioxide & other greenhouse gas levels is even more important, as previous models took the sun's output to be constant.
If that's not the case, well, even a tiny increase in solar output can have drastic consequences. That makes our efforts more important than ever.
That prototype of Starship was not expected to reach space. The main successful outcome of the test was for Starship to lift off and get away from the launch facility which it did, although not really with expectations. The biggest failure though was the flight termination system took to long to rip open the tanks as they misjudge what it would take to rip those tanks apart. Even now, Elon Musk has stated he thinks the second test flight only has a 50/50 chance to reach orbit. These test flights goals in the early stages test not just the rockets ability to get to orbit but to test things like correlation for data for Max Dynamic Pressure, Aerodynamic Flight (although first starship flew even with outdated flap designs), now Hot Staging, etc. I'm confused how people still don't understand that SpaceX has a different way of testing rockets than other companies even though it has been stated hundreds of times by SpaceX and all of Starbase watcher youtubers that put out better news videos than 99% of the news agencies in the world.
The delays in the Starship lander are more likely due to environmental agencies pushing back, possible legal battles with jealous competitors, etc. Not due to what the media considers a test flight failure when SpaceX considered it a success for what the test flight was meant to achieve.
Just like the Falcon 9 prototypes. Falcon 9 now flies 2 - 4 times a week without issue.
11:19 so the freeze ray does the same thing a fan would do, not only in theory but also literally. A few degrees cooler in specific objects.
Thank you for the science news.
I probably misunderstood what I was reading, but …if mass gets added only when a certain type of weird particle is added ( I’m feeling dizzy already!) then it occurs to me to ask when/how does time get added? That is, given time seems to be a “plug” in the equation, when you start backing out the speeds of the guys with the flashlights - one on the train and the other standing still, and we’re holding the speed of light constant, …is there a thing that adds time to go with the mass? Light is constant… Photons have no mass but they move and oscillate… Space-time is lumpy… What, then, is giving us this mirage of time? Or maybe I’m asking what gives us this mirage of distance, within which we keep trying to impute a concept of time? What exactly is “time?” Or I guess in the phrase, “spooky action at a distance,” is there a way to treat that distance like constant and plug something else we’ve always assumed was deterministic? Help! I’ve fallen and I can’t get up!

welcome in the audience, do you know her music-videos?
A few days ago I posted a question. This question is sort of a follow on... I assume ask my questions are too basic to be real questions, but rather are kind of study notes as I try to work through the subject matter. In that ... light... here's my current progress and my next questions...
Based on the video linked below, I have this bit -- if observations of electromagnetic energy give us the illusion of spacetime, and entropy is something like the same kind of illusion for quantum mechanics, and electrons have this weird "demon" state (when they aren't turning into anti-electrons?), then don't we need to suppose an on-off switch for "existence" as part of existence? I mean, quantum entanglement only looks like that because during part of the experiment some of the particles were "off" and then came back "on"? The observer would assume "time passed" and "distance was traveled" but really it was just a state change to "off" and then to "on" for existence ...of the entangled ... um... information? If, as in the end of this video, existence is kind of a crunchy quantum sand, then we just need to describe the sand when it's "off" right? It would be fun to make that description consistent with dark matter. Right? So what is that then? What's the current thinking on unobservable states that blink on and off at different readings in spacetime? I'm feeling very dizzy.
Here's the video I that's got me trying again to form a coherent question about gobbledygook!
Keep doing your amazing awesome work! My kids and I are enjoying the hell outta this! (Well, I am!)
ua-cam.com/video/yPVQtvbiS4Y/v-deo.html
It isn't so much that things come into existence as that energy changes shape, so to speak. One collection of particles can change into another collection of particles, thank to quantum mechanics, provided that all conservation laws are concerned. It doesn't help with dark matter exactly because energy is conserved. You can't just make matter out of nothing.
@@SabineHossenfelder I forgot about conservation, believe it or not. 🤦♂️ But when I was saying "off/on" I meant observable / not observable. I'm feeling like there is a presumption that time is passing built into the explanations of light having a finite speed, stuff we measure using light, and ideas like the expansion of the universe. Obviously this stuff is beyond me, but it's fun to try. But spacetime is one word now. So I'm ...my brain can't hang on long enough to walk this thought all the way through. A singularity requires dividing by zero. Something ain't quite right! Then again, I am just now trying to understand the Higgs field. Also, I keep trying to imagine a "field" as something akin to a sheet of vibrating plastic wrap in space, rather than as "any equation that makes good predictions."
Keep going! We need you!♥️
Two words you never imagined you would hear together: Quantum Enchilada

If it is really weak, we should call it "attempt" instead of "force"
Or perhaps we could call it a 'cajole'
A "polite but firm suggestion"?
A "nudge"?
I’m no physicist, but your videos make me feel like one! Hey might up and down quarks be the equivalent of the peak and the trough of a wave? I’m sure that’s been debated, but I’d love your take on that rabbit hole. I’m trying to think: if the peaks of waves happen to coincide, that’s the kind of thing that would spike up enough energy to make a state change to matter, right? Or mass? And in radio, you have carrier waves that😵💫 kinda ride along on the main wave? The weak force strikes me some kind of background noise that, if we had a model, might be just enough “carrier wave” to “pay for” that state change? The gap I have never understood is this: through what medium are all these waves oscillating? I end up thinking of a field as a medium, like a fluid. I assume I’ve lost track of conservation of energy now. But it feels like we need to reframe quantum stuff in terms of turbulence and then speculate about why we can’t detect the medium more easily. If we can’t measure something, but we can see an effect, isn’t that a dead give away that we need to get outside the model we have? I’m trying to imagine Newton seeing a cannon ball and the moon as equivalent, though that violated a lot of contemporary assumptions. Where’s the pervasive medium for all these waves? Can we “see” it at absolute zero or something? What would it look like if the medium was, uh, “dried up” at some spot? Is that the evaporation at the end of a black hole, or max entropy, or like a primitive, “…where’d it go?!” On the other hand, what if there was a tsunami one day? Fluid mechanics gets described by chaos and fractals I guess. Why don’t I see more comparisons to fluids as an analogy for the noise in subatomic physics? We have the wave idea. What happened to the medium? Like why isn’t the transition from “energy“ to mass-bearing particles similar, say, to the disruption of laminar flow at the leading edge of the wing of a supersonic jet? Obviously, whatever that state change is, it can cascade…(fission) …so what’s the “water” doing just before it evaporates? If you go faster than light do you spontaneously become matter? Is gravity the effect of matter trying to “cool off” back to energy? Is that why time is a weird idea? You can only tell time by noticing changes in the height of these waves, or…what? Please discuss…?
Well they have different masses, so not sure how that would work.

If they de-orbit the ISS by 2031, are they going to do it the same way the Chinese do it, i.e. by just letting nature (i.e. gravity) take its course, so that it falls randomly on the part of Planet Earth which happens to be the most unlucky at the time? Perhaps it will fall on Tien An Men Square? The Chinese would like that.

NASA blaming SpaceX for the delays is pretty funny considering there is no sign of Artemis 2 before the end of 2024 (more likely 2025)
and especially when the HSL wat slated for NEXT year. I think NASA doesn't fully appeciate how fast Space-x work.
Correction: the Starship test flight did not fail to separate. It did not get that far in the timeline and the separation was not attempted before the flight was terminated.
Multiple engine failures among other problems ended it early. It’s most impressive feat was spinning out of control at peak atmospheric drag forces and remaining in one piece.
Yeah, I was hoping that one would make it a bit further than it did... big rockets are cool. here's hoping the next attempt goes a bit better?
This was just a test of the ground systems and ability to launch. SpaceX blew up lots of Falcon 9's before ever putting customer payloads onboard.

In fact, every goal SpaceX had for the "4/20" launch was met or exceeded. The wish, to actually achieve orbit, was just that. The requirement, to gather useful design and performance data while developing/refining flight procedures for such a bird, was not only met.
In the time since the OLM has been re-designed, re-built, radically enhanced and tested. Staging has been re-designed and a test article "can-crush" tested. Some hot-stage article will soon be installed on a modified B9 (it looks like). And as Musk said, a couple more meters of det-cord is all the self-destruct needs.
NASA never has and never will move like that. Politics don't permit it.
JUST like they did when prototyping the Falcon 9. Falcon 9 now reliably launches twice a week from Florida and once a week from VA or CA.
@@ShotgunAFlyboy Exactly. If the politically-motivated haters can be kept at bay, Starship will be operational next year and will fly just like Falcon 9.
I mean, look how much when wrong on 4/20, and it still ascended. That stainless bird could just be a beast.
Between his costume change for the freeze ray segment and calling up Sabine to talk wine, Albert is the real star of this week's episode.
15:02 the spaceX insisted that the goal for that starship test was to simply pass the launch towers. It met that goal, no? How come that starship test is related to a delay for Artemis?
Its definatly not causing a delay yet and the test is not a cause for concern. I suspect Starship will be ready for 2025 but Artemis won't. But there is a lot still to do for starship to be ready. They will have to land on the moon at least once before NASA will certfy it for people. That means they will need to make a new or servearl new launch towers as they can't launch from Boca as there launch licence prevents them. They also still need to do in space refuling, somthing that has never been done before. Dear moon will happen first for sure. I hopeing for late 2025 but wont be suprised if that slips a couple years who knows!
@@R0nBurgundythat is very reasonable but I think the video was (unintentionally, I’m sure) misleading in directly pinning the delay of Artemis to Starship’s integrated test, see 14:45. It is also factually incorrect in saying the test did not work out as planned.
As a proud patreon and long-time viewer, this is a bit disappointing.
Seems like politicians are trying to throw SpaceX under the bus to cover for corruption in some of the other vendors that fell behind on Artemis. We all saw how many times A1 had to scrub. It got pathetic watching several Falcon 9's and a Falcon Heavy launch in the time that A1 kept scrubbing and scrubbing and scrubbing.
i'm in my late 30s. one of my favorite shows as a kid in the early 90s was "beyond 2000" on the discovery channel here in the states. (RIP "discovery" channel and the "learning" channel) your YT comes as close as any to sharing the same spirit as that show - showing and telling about what's to come.
The sun is exactly as bright as I always thought it was.
Now excuse me, my optometrist is calling.
15:00 - inaccurate:
- the whole development is slower than expected - not just one test showing problems
- it didn't "fail to separate" - it never reached altitude for separation - that was due to engine failures (some engines failed to begin with, and more likely caused by debris from obliterated concrete under launch pad ; it was so powerful, it compressed the earth, "snapped" the protective heat resistant concrete and shattered the whole thing from the inside (most likely) digging a huge crater)
- the test itself was not "planned" to reach any point, and apart from that, the vehicle performed "better" than they expected (well, it was a test to find out - they did not know)
- Also, there were issues with detonating it, as it was sturdier than expected. - (That was probably the biggest "safety issue" - my opinion, as if it veered off course, it would not be destroyed in time. But, it's an easy to solve issue once known.)
- so, is the situation better or worse? I don't know. I'm just correcting small details in this video. - The overall message is correct: it's taking longer than Elon hoped ... but that's true for most projects and companies; Elon especially has very optimistic expectations...
Fermilab: "we need to find a way to get more accurate data."
cern:"we need money for a bigger accelerator"
Beauty and science with humour. What an excellent teacher..
Perhaps this isn't a fifth force, but a detection of what gravity really is. As EM waves pass through sub atomic particles they change their position slightly to maximize attractive force and minimize repulsive force, resulting in a tiny net positive.
10:31 considering its the airforce i assume they need it to condense propellant for a plane so it takes less space or to cool the surfaces of a really fast aircraft (probably the sr-72 darkstar program which will probably be flying at 8 Mach which would be why it would need cooling, especially if its got the same radar absorbing materials as the b-21)
Honestly, Artemis has been going way too smoothly, I'm glad they found some issues before getting to manned missions. The timeline was ambitious to begin with.
to smoothly? What planet are you from. Artemus was suppose to launch in 2017? Then 2019 then 2020 then 2021 then 2022. Do you forget the Boeing debacle, of the core stage, ML fiasco and VAB over budget issues, This program has been a mess...
Well it is a bit ambitious to slot in a criticality one subsystem that is a lunatic (pun inpunded). Muskus might deliver you a landing craft. He might deliver you a space toboggan. He might discern that Mars is in fact the actual god of war and retask his space division to produce grappling hooks to enable a landing crew to take a celestial body by force. Ok Diana, hunt THIS.
You are joking, right? SLS has been a mess for many years now.
Artemis is a welfare program for the usual MIC contractors. SLS is a complete waste of money and using solid boosters is dangerous for human launches. Just let SpaceX do it on private sector money!
A useless project masquerading as science. Its only success is using ressources that should have been used for real science projects

One of the major messages from this episode appears to be “more science and less sensationalism”. I completely agree.

It is interesting to see how the elemental factors which interconnect to create their resonance with each other are continuously being discovered and redefined.
@@buddygrimfield7954 Try to see how your statement is so vague as to be almost meaningless. Elementary aspects of physics are not being continuously discovered; it happens fairly suddenly only every so often. The last major theoretical discovery I can think of is the Higgs boson in around 1962. (It can be said to be discovered then, even though it was not observed until around 10 years ago, because it is necessary for the standard model to be considered valid-which it is, even if it is not complete.
I can see how I could have worded my (uneducated) opinion regarding my interest in how the interconnecting relationship between the known physical forces are continually being redefined a bit better than I did. But it was merely a casual comment. So, if it offended you so badly that you feel the need to "correct" me about it, perhaps you have far bigger issues than my casual comment being "almost meaningless" as you put it.

We would also expect to see cooling around the other melting glaciers around the Earth, so this blob seems to be a far greater cooling effect then just cold water being introduced to the oceans
Time to dredge up a joke from the eighties:
"Yes, they've found a fifth force. However, they've also found a sixth force which exactly cancels it out."
I dont feel too bright when i watch these videos
That's okay, there's a few of us that feel like that. We come away with more cool facts though.
Time to recharge those batteries...
I think half because: the methods that most of this research employ is often new and unique. It can require some extra watching even for a scientist. The other half because Sabine goes through it quite quickly and lets not forget this basis of science that we keep building up, is built on many hundreds of years of intensive research. You basically get only some flavors even with a scientific study.
Welp, 1 more video before sleep, it's 12:45 a.m here in Malaysia ^^
Your sense of humor is so German. I love it! 😂
My favorite channel by far. Thanks Sabine.
Women with superior intelligence are wonderful.
This is the type of news I like. Thank you!
love your content, keep it up
Amazing how many people dissed Sabine for saying that LK99 was probably like the other room temperature superconductors, fake. Time for them to fess up and apologise!
Do I see a flying pig
I'm glad Brookhaven found my muon g -2s and their deviations from those predicted by the standard model. I've been going up the GD walls looking for those things, now I remember leaving them there. They can keep all five of my Sigmas, I've hated the Greek letter ever since my Ma bought me that Huffy Sigma for my 11th birthday back in '85 and all the kids in the neighborhood relentlessly tormented me because of those stupid discs over the spokes.
9:32 *best Mr. Freeze voice* "Alright everybody, chill!"
Saying that the first Starship "did not go as planned" is a bit misleading. Yes, the Starship did not make it to orbit but that was not the primary goal of the mission. The main goal of the launch was to gather data and not blow up on the pad. It did do that. Also the mission disposed of some materials they no longer need to store and it also "helped" with the pad excavation work SpaceX had planned. Come to think of it, maybe based on this new technique, Elon should add Raptor engines to the front of his tunnel boring machine.
I love your subtle (technical) humor. I wonder how many 'get' it. Great channel!
9:23 You're mistaken, the cold blob is clearly intelligent lol
I have to say, "the telephone will ring" was exciting to hear. Thanks for making science fun!
