I wonder when Sabine will do another take on LK 99, after so many other labs seem to replicate the experiment. I agree levitation != SC, but it may be a new CuO based superconductor or at least the phase diagram would be interesting.
Hyperloop in Munich... how long will they need to understand that the loops, i.e., curves are the problem? Did they do their homework on why previous attempts failed?
It's worth remembering that Hyun-Tak Kim, one of the 6 co authors, wrote a paper on diamagnetic shielding for high temperature superconductors in 2001. It would be very weird if he didn't realize LK99 was simply diamagnetic
And Kim was supposedly involved in synthesizing the stuff in 1999 (~ 1:56 in the video), two years before the study you mention... suspicious timing, almost as if both papers are talking about the same subject, and the second came after rejecting the idea behind the first paper.
One big thought i got in all these is that if it is a new superconductor it will definitely be a new type, we know type 1 workarounds with the BCS theory, we don't know how type 2 work until today, we do see that Meissner effect tends to be more ineffective with higer temperatures, being type 1 perfect diamagnetics, type 2 not so much letting magetic fields that allow quantum lock. So why a new type RTSC wont present an altered form of Meissner effect? I think the video isnt a let down i need to see resistance measurments.
Yay ! I was so looking forward to hearing Sabine's opinion on this announcement. I trust her reporting. I'm on tenterhooks to discover if the room temperature superconductor is the real deal.
It's been 4 days and no one reproduced it, everyone that tried failed and still didn't publish because they need to do verification, if this was real and people got positive results it would be out already. The video is indistinguishable from pyrolytic graphite, so don't hold your breath.
@@RinatMenyashev I happen to know a PhD candidate in Material Science at Standard who's work is on high temperature superconductors. The high temperature in this case means 50 kelvin rather than 4 kelvin. He says that LK-99 is basically a scam because the results are impossible to replicate, yet.
It's maybe a silly idea but I wonder if the quantum radar could apply to radio waves. It would be great to get a stronger FM signal while driving. I believe this can work because I too drive in a dilution refrigerator.
The process requires comparing photons, so it doesn't work for the FM radio, where only one direction communication is happening. However, you can forget FM. New cars will have internet radio in them...
I thought the issue of superconductivity at room temperature was solved 30 years ago when a group of Siberian scientists solved it by working on room temperature.
When I hear of something "new and exceptional" in science I'm always happy, and my second think is "Will it pass Sabine's scrutiny"? And it does not in too many cases, showing how premature and superficial are many claims. Science is hard and the rules are strict. Thank you for this work in support of reliable research, Dr. Hossenfelder, maybe you gain some enemies in the community of researchers, but also gain our esteem.
Thank you Sabine, I really like this science info format. At 15:30 the “Hyperloop” made in Germany, 🤔 MagLev trains are old news, they achieved speed of 603 km/h in 2015 and wheeled trains speed record is 574.8 km/h. The qualifying property of the Hyperloop is “under vacuum”, I saw the door looks like a hi vac system door. Did they achieve operational pressure during the test? How long it took to pump the chamber down to that state? Most importantly, are the costs and are the costs and safety risk, of hundred of kmeters long vacuum chamber being addressed and are they worth an increase of 30% of the top speed? I share Thunderf00t skepticism about the viability of an idea that’s 100 years old!
There is no Hyperloop. It's just a handy way to have an interesting project for students to work on, to get attention from the media, and to secure funding from the Bavarian state government who just loooooves things like this, no matter how ridiculous it may be. They like to present Munich as some kind of super-innovative European Silicon Valley (which admittedly is not entirely unsuccessful).
Thunderf00t was rightly skeptical. Note how the companies that "invested" in hyperloop R&D have quietly evaporated, one after the other. "I swear, it's not that hard" said a famous person.
I'm baffled that the Hyperloop is still being considered as something that could happen. Can you imagine the amount of g force this thing would generate? And any leak in the transport vehicle or the tube would be catastrophic.
Yeah but the speeds involved are similar to speeds in commercial passenger jets (I'm talking about the 800km/h figure, not transonic speeds), so wouldn't the g-force generated by acceleration to those speeds also be similar? And those jets also have to be robust against leaks and depressurisation. The technical challenges seem difficult but not insurmountable, and the aviation industry has at least partially dealt with some of the challenges.
With flight there are large amounts of area to make gradual high-speed turns. Plus, you have the friction of air and pressure to balance and control air speed. You don't have that with in vacuum tube. As for leaks. Consider the tragedy of Payne Stewart's flight. A similar disaster would shut down the entire line for potentially days or weeks. You don't have this problem with air travel. Now let's say it's the tube itself that fails. The sudden rush of atmosphere filling this vacuum tube would turn the train into the equivalent of a bullet being fired through gun barrel. @@abhinavnatarajan4180
The approach for LK99 is interesting. So even if we don't get it now, it could be a way to eventually get there. The idea is the following: There are already superconductors at higher temperatures, but they require extremely high pressure in order to be superconducting. Those superconductors rely on a kind of quantum effect where the electrons are bundled together. The key lies in modifying the molecular structure in a way that it does that itself without the high pressure. Their idea was to replace some atoms with other atoms that take up less space / have weaker fields. That way the structure flexes and that flex apparently allows for this quantum effect to happen. Let's see. If it works I'm sure we will get a video of Sabine explaining that concept. If not, well, I hope that that is at least a step towards a solution sometime in the future.
The key idea for achieving room-temperature ambient-pressure superconductivity is to create electrically charged bosonic drift. Electrons are fermions. It takes two of them coupled together to form an electrically charged boson. It takes *strong* electrical field to bind together the two electrons. Small cations can create this condition better than large ones. Now to drift the electrically charged bosons, we can move the electrons much easier than the cation coupling them. As long as they can get through to a nearby cation, the coupling can continue. To make the drifting easy for the electrons, we need to make the potential energy barrier against their tunneling thin. In a crystal lattice, making a smaller unit cell can squeeze the energy barriers into a smaller space.
I love everything about this format. Only the sponsor gave me pause: I would have expected Sabine to explain the business model critically of an outlet which can sponsor the show (for money, I suppose) yet does not charge for its product. Oh, wait.... the newsletter which Sabine advertised is NOT their product ? WE are ?!
Yup, it's yet another data harvester that at the same time seeks to indoctrinate you with biased content, whoever pays them the most will be given 'reliable source' mark...
It happens that I have my PhD from Amsterdam based on experimental superconductivity, time ago. These 2 Korean papers are not impressing me. Differences between both are devastating reputation of authors. We had many cases of claims for Hi T superconductivity. My impression is that the authors do not even have good skills in preparing graphics for presentation. The last paper presents a "Meissner" effect that is so small and measured very inaccurately. If they asked me for advise ;)
I want to get the quantum metrology report! ... thanks Phill, in other news DC is experiencing excessive quantum discord after discovering the president was somehow in the spineless singlet Schrödinger state: 1/2 |alive> + 1/2 |dead>, negating the zombie bozo hypothesis as well as the weakend at Bidens conjecture... spooky. Back to you Albert.
It seems like LK-99 was reproduced, though we haven't received any papers on it just yet. Several lab simulations have shown that it is more likely to be a super conductor than not given it's apparent diamagnetic properies. If you've been keeping up with it the last few days do you have any new thoughts about it?
Do away with the lead. It's not a new thought but important for not becoming the somewhat crazy ancient Romans who made wines in lead vessels to sweeten them.
Maybe try using magnesium but it may be somewhat dangerous if residual oxygen is still in there to combust the magnesium. A different synthesis formation process may be required. Titanium has a +4 oxidation state so it may also work well with +2-oxidation-state cation such as Mg+2, Fe+2, Cu+2.
Do keep good scientific records in an engineering notebook so others can see the reproduction procedure. It may come in handy should patent lawsuits come about and judges need evidence to settle them. Alexander Graham Bell and Elisha Gray had a patent conflict at the invention of the telephone so no erasure, only crossing out and rewriting, no ripping away of any pages or taping on any additional page(s), date whenever starting to work on an idea or continuing to work on an idea, get other knowledgeable colleagues to witness and sign any potential patentable results, get these results notorized, etc. We should try to emulate the good art/military/scientific/architectural/design/engineering practices pioneered by Leonard da Vinci. May the awards and rewards go to the worthy ones. The brave ones don't need the guidance computer going to land upon the Moon or going straight in to kill the Death Star. 🎉
Lawrence Berkeley's simulation seems to think there's some credibility to LK-99. Discrediting the paper just because you can't read the language seems premature.
I don’t think so. How many other times have room temperature superconductors been debunked? Literally every single one so far (let’s be clear this one might not work either). Therefore her judgment that it will probably not work with a pretty good guess. What matters now is what she does with this new information!
"Wow, that prediction aged poorly quickly. Big hit on your trustworthyness" Her prediction aged like fine wine. Don't get carried away by the next hype bubble.

Based on the effects this discovery would generate, they don't deserve the Nobel Prize. They deserve something else entirely. This could very well change the course of human history.
Not really verified, but different labs have had some interresting results, I think more patience is needed, one thing is sure, this material have some interresting properties that are worth studying closer. We need patience and I think this room temperature SC structure is very hard to make consitently, they made it first by mistake in 1999! and spend until now trying to refine the method for making it reliably. They didn't even succeed, but drama lead to early release of the material.
Jesus. Forget the Nobel prize. This would change civilization. People would remember these guy's names after everyone's forgotten about the Nobel prize
Breakthroughs rarely happen, if at all. When someone says they have massively improved something it usually means either they have not, or the marketing department has gotten ahold of the announcement and is making a huge deal out of something that"s actually smaller, and has taken years to accomplish with small improvements every year.
Love for LK-99 to live up to the hype! Still skeptical but those electron channels remind me of some of the work done by Brown and MIT involving twisted multilayer graphene. ^.^
It seems legit to me, because even if the floating magnet is turned around, and pushed back into the original position, it floats again. That means the magnetic field of the base isn't fixed, but induced by the floating magnet on top. One side of the magnet is heavier, that explains why the heavy side touches the surface (it's too heavy to float). Maybe they made the video in a hurry and this was the best magnet they could find that was strong enough to float. Well, we'll see what happens in the future.
Superconductors exhibit perfect diamagnetism. They don't necessarily exhibit flux pinning. Those are two separate phenomena, so the piece needing to be in contact to avoid sliding off is not proof that it's not a superconductor.
Yes, thank you Sabine for the word "Daimagnetic". I knew instantly from the video of the half-baked piece of magnet trying to levitate did not pass the bar. Why can't we just build a super AI computer and ask for the right formula if we promise to worship it forever? We need more power, just like we need more coffee & tea!!!
It's pyrolytic graphite, and people should had it reproduced today, nobody did, everyone that tried failed and are checking for any error before they call it debunked.
It's called a hyperloop because it's being built because of hype, as opposed to because it's a reasonable use of resources. It's a trend in technobabble circles, especially in Musk-adjacent projects.
And each company that develops a prototype is looping back to square one. As if maglev technology doesn't already exist, for one obvious example. Just don't tell the investors! 😏

Those guys from cold fusion should join up with these super conductor guys, maybe they can invent time travel?
That was already invented in 2042.
"Lukewarm superconfusion"
I wonder when Sabine will do another take on LK 99, after so many other labs seem to replicate the experiment. I agree levitation != SC, but it may be a new CuO based superconductor or at least the phase diagram would be interesting.
She just retreated this on twitter.
@@aleksfadini you mean she Xed?😂😂
Hyperloop in Munich... how long will they need to understand that the loops, i.e., curves are the problem? Did they do their homework on why previous attempts failed?
Monorail monorail
The aesthetics of this production is just mad! Reminds me of late 90s TV. Quite fun.
I'm glad you addressed AMOC news. Too many headlines about the gulf stream collapsing by 2025.
Been waiting for your view on LK-99! Nice!
It's worth remembering that Hyun-Tak Kim, one of the 6 co authors, wrote a paper on diamagnetic shielding for high temperature superconductors in 2001.
It would be very weird if he didn't realize LK99 was simply diamagnetic
And Kim was supposedly involved in synthesizing the stuff in 1999 (~ 1:56 in the video), two years before the study you mention... suspicious timing, almost as if both papers are talking about the same subject, and the second came after rejecting the idea behind the first paper.
Superconductors _are_ diamagnetic. They exhibit superdiamagnetism. Flux pinning is not seen in all superconductors.
One big thought i got in all these is that if it is a new superconductor it will definitely be a new type, we know type 1 workarounds with the BCS theory, we don't know how type 2 work until today, we do see that Meissner effect tends to be more ineffective with higer temperatures, being type 1 perfect diamagnetics, type 2 not so much letting magetic fields that allow quantum lock. So why a new type RTSC wont present an altered form of Meissner effect? I think the video isnt a let down i need to see resistance measurments.
Need update on replication!!!!

Yay ! I was so looking forward to hearing Sabine's opinion on this announcement. I trust her reporting.
I'm on tenterhooks to discover if the room temperature superconductor is the real deal.
It's been 4 days and no one reproduced it, everyone that tried failed and still didn't publish because they need to do verification, if this was real and people got positive results it would be out already. The video is indistinguishable from pyrolytic graphite, so don't hold your breath.
Never gonna happen.
lk99 is not the solution, but it might create a path
If LK-99 is legit, it doesn't just mean "please give us a Nobel Prize"
It means "When can I pick up my 2024 Nobel Prize?"
Hence this fuss around publishing, they truly believe in what they did
@@RinatMenyashev I happen to know a PhD candidate in Material Science at Standard who's work is on high temperature superconductors. The high temperature in this case means 50 kelvin rather than 4 kelvin.
He says that LK-99 is basically a scam because the results are impossible to replicate, yet.
Korean prize
'Yet' is crucial here. As of now we have 3 reports of successful replication, and lots of failures.. anyway a good staying point
@@RinatMenyashev three successful replications?? I couldn't find any sources on Google. Can you please provide some links?
"Could make the hyperloop a reality"
Yeah we know that electrical resistance and power consumption aren't the major hurdles for that BS tech.
Still, I hope it is a superconductor.
It's maybe a silly idea but I wonder if the quantum radar could apply to radio waves. It would be great to get a stronger FM signal while driving. I believe this can work because I too drive in a dilution refrigerator.
A superconductive antenna itself would have zero loss.
The process requires comparing photons, so it doesn't work for the FM radio, where only one direction communication is happening.
However, you can forget FM. New cars will have internet radio in them...
I thought the issue of superconductivity at room temperature was solved 30 years ago when a group of Siberian scientists solved it by working on room temperature.
room temperature ROOM PRESSURE is the important part

They are transparent about the manufacturing process. To peer review, all you have to do is make it yourself.
When I hear of something "new and exceptional" in science I'm always happy, and my second think is "Will it pass Sabine's scrutiny"? And it does not in too many cases, showing how premature and superficial are many claims. Science is hard and the rules are strict. Thank you for this work in support of reliable research, Dr. Hossenfelder, maybe you gain some enemies in the community of researchers, but also gain our esteem.
May the forest be with you Sabine
If I could genuinely understand a quarter of this video I would feel pretty smart. I cannot though.
These videos simultaneously make me feel very smart and very stupid. 🙂
Yo what's a link to that twitch stream? I'll give him a follow and watch him do science!
You and Anton make the best science news videos
Thank you Sabine, I really like this science info format. At 15:30 the “Hyperloop” made in Germany, 🤔 MagLev trains are old news, they achieved speed of 603 km/h in 2015 and wheeled trains speed record is 574.8 km/h. The qualifying property of the Hyperloop is “under vacuum”, I saw the door looks like a hi vac system door. Did they achieve operational pressure during the test? How long it took to pump the chamber down to that state? Most importantly, are the costs and are the costs and safety risk, of hundred of kmeters long vacuum chamber being addressed and are they worth an increase of 30% of the top speed? I share Thunderf00t skepticism about the viability of an idea that’s 100 years old!
There is no Hyperloop. It's just a handy way to have an interesting project for students to work on, to get attention from the media, and to secure funding from the Bavarian state government who just loooooves things like this, no matter how ridiculous it may be. They like to present Munich as some kind of super-innovative European Silicon Valley (which admittedly is not entirely unsuccessful).
Thunderf00t was rightly skeptical. Note how the companies that "invested" in hyperloop R&D have quietly evaporated, one after the other. "I swear, it's not that hard" said a famous person.
Being a former student at TUM, I'm quite ashamed that my alma mater is involved in this nonsensical hype...

3:10 a minor correction: There are seven authors in total, young-wan kwon being replaced by hyun-tak Kim on the latest submission.
You know it's an important discovery when they start in fighting over who should get the most credit!
Big "maybe", it also shows that the lab probably has bad practices, internal feuds and poor management in general.
Now we wait for the movie.
Or there is a breakdown in the team over how to salvage years of work that likely wont lead to anything significant
Whiye people gonna claim they discovered it 😂
@@baekdumountaintiger5701 Wait what? Since when gun powder was claimed to be a western invention?
Sabine is wrong with her suspect as always😂
I'm baffled that the Hyperloop is still being considered as something that could happen. Can you imagine the amount of g force this thing would generate? And any leak in the transport vehicle or the tube would be catastrophic.
I just translate that to actual reasonable alternatives
Yeah but the speeds involved are similar to speeds in commercial passenger jets (I'm talking about the 800km/h figure, not transonic speeds), so wouldn't the g-force generated by acceleration to those speeds also be similar? And those jets also have to be robust against leaks and depressurisation. The technical challenges seem difficult but not insurmountable, and the aviation industry has at least partially dealt with some of the challenges.
G-forces are related to acceleration, not velocity, so not a problem if acceleration properly controlled.
With flight there are large amounts of area to make gradual high-speed turns. Plus, you have the friction of air and pressure to balance and control air speed. You don't have that with in vacuum tube. As for leaks. Consider the tragedy of Payne Stewart's flight. A similar disaster would shut down the entire line for potentially days or weeks. You don't have this problem with air travel. Now let's say it's the tube itself that fails. The sudden rush of atmosphere filling this vacuum tube would turn the train into the equivalent of a bullet being fired through gun barrel. @@abhinavnatarajan4180
Elon after hearing Sabine say that LK might make the hyperloop a possibility:
I've been right all along🤓😮
extraordinary claim needs extraordinary proof.
The approach for LK99 is interesting. So even if we don't get it now, it could be a way to eventually get there. The idea is the following: There are already superconductors at higher temperatures, but they require extremely high pressure in order to be superconducting. Those superconductors rely on a kind of quantum effect where the electrons are bundled together. The key lies in modifying the molecular structure in a way that it does that itself without the high pressure. Their idea was to replace some atoms with other atoms that take up less space / have weaker fields. That way the structure flexes and that flex apparently allows for this quantum effect to happen.
Let's see. If it works I'm sure we will get a video of Sabine explaining that concept. If not, well, I hope that that is at least a step towards a solution sometime in the future.
The key idea for achieving room-temperature ambient-pressure superconductivity is to create electrically charged bosonic drift.
Electrons are fermions. It takes two of them coupled together to form an electrically charged boson.
It takes *strong* electrical field to bind together the two electrons. Small cations can create this condition better than large ones.
Now to drift the electrically charged bosons, we can move the electrons much easier than the cation coupling them. As long as they can get through to a nearby cation, the coupling can continue.
To make the drifting easy for the electrons, we need to make the potential energy barrier against their tunneling thin. In a crystal lattice, making a smaller unit cell can squeeze the energy barriers into a smaller space.
Odd number of electronic charge on a cation disqualifies it from forming an electrically charged boson. So sodium is out and magnesium is in.
by elon "inventing" hyper loop, you mean robert goddard coming up with the vac train in 1904
Hm... so you discover room temperature superconductive material but decide to publish the paper in an obscure local publication instead of... Nature?!
I love everything about this format. Only the sponsor gave me pause: I would have expected Sabine to explain the business model critically of an outlet which can sponsor the show (for money, I suppose) yet does not charge for its product.
Oh, wait.... the newsletter which Sabine advertised is NOT their product ? WE are ?!
Yup, it's yet another data harvester that at the same time seeks to indoctrinate you with biased content, whoever pays them the most will be given 'reliable source' mark...
seriously.. u think Sabrine, just goes into the bathroom, does a video.. maybe production team?
It happens that I have my PhD from Amsterdam based on experimental superconductivity, time ago. These 2 Korean papers are not impressing me. Differences between both are devastating reputation of authors. We had many cases of claims for Hi T superconductivity. My impression is that the authors do not even have good skills in preparing graphics for presentation. The last paper presents a "Meissner" effect that is so small and measured very inaccurately. If they asked me for advise ;)
ah, sabine, you are so delightful. how insightful and witty you are! thank you for the work you do to make science accessible
I want to get the quantum metrology report!
... thanks Phill, in other news DC is experiencing excessive quantum discord after discovering the president was somehow in the spineless singlet Schrödinger state:
1/2 |alive> + 1/2 |dead>,
negating the zombie bozo hypothesis as well as the weakend at Bidens conjecture... spooky. Back to you Albert.
I cracked up so hard at the suggestion to make sure dark matter is not a giant eel.
As a Bigfoot who identifies as a misunderstood hairy lumberjack, I absolutely empathize with your mirthful analysis.
Hyperloop's a waste of resources.
Evacuating kilometres of tunnels would be time-consuming and waste lots of energy.
Thank you. When I saw the superconductor claim in the news, I thought “ I don’t trust it. I’ll wait till Sabine talks about it “
It seems like LK-99 was reproduced, though we haven't received any papers on it just yet. Several lab simulations have shown that it is more likely to be a super conductor than not given it's apparent diamagnetic properies. If you've been keeping up with it the last few days do you have any new thoughts about it?
Do away with the lead. It's not a new thought but important for not becoming the somewhat crazy ancient Romans who made wines in lead vessels to sweeten them.
Maybe try using magnesium but it may be somewhat dangerous if residual oxygen is still in there to combust the magnesium. A different synthesis formation process may be required.
Titanium has a +4 oxidation state so it may also work well with +2-oxidation-state cation such as Mg+2, Fe+2, Cu+2.
Cu has multiple oxidation states. Could that have made the repeatability of producing the superconducting sample difficult ?
Do keep good scientific records in an engineering notebook so others can see the reproduction procedure. It may come in handy should patent lawsuits come about and judges need evidence to settle them.
Alexander Graham Bell and Elisha Gray had a patent conflict at the invention of the telephone so no erasure, only crossing out and rewriting, no ripping away of any pages or taping on any additional page(s), date whenever starting to work on an idea or continuing to work on an idea, get other knowledgeable colleagues to witness and sign any potential patentable results, get these results notorized, etc.
We should try to emulate the good art/military/scientific/architectural/design/engineering practices pioneered by Leonard da Vinci. May the awards and rewards go to the worthy ones. The brave ones don't need the guidance computer going to land upon the Moon or going straight in to kill the Death Star. 🎉
A superconductor is in fact a diamagnet, a perfect one at that.
yes im confused by this statement by her...
Yes, Meissner effect produces superdiamagnetism. Flux pinning is actually caused by imperfect diamagnetism, and is not present in all superconductors.
Lawrence Berkeley's simulation seems to think there's some credibility to LK-99. Discrediting the paper just because you can't read the language seems premature.
Wow, that prediction aged poorly quickly. Big hit on your trustworthyness
I don’t think so. How many other times have room temperature superconductors been debunked? Literally every single one so far (let’s be clear this one might not work either). Therefore her judgment that it will probably not work with a pretty good guess. What matters now is what she does with this new information!
"Wow, that prediction aged poorly quickly. Big hit on your trustworthyness"
Her prediction aged like fine wine. Don't get carried away by the next hype bubble.
Muscles are designed for activities in your brain to change and move stuff out side. So why can't our minds and mood change temperature of of a room or air pressure our lungs and skin do or hole bodies do
Beautiful, was wondering when we’d hear your take on the big news!
Yep, the video didn't look like a super conductor floating above a magnet to me either. Not sure how so many people got so excited about this.
I don't know enough about superconductivity to judge anything here. i didn't get too excited, though.
Nice to have it in perspective, now :)
I was expecting Sabinas's considerations after Anton Petrov and here it is
How crazy would it be if all the dark matter in the universe was just a giant eel though? 27% of the universe, just one really long eel playing that old Snake game from flip phones, slowly eating all the galaxies.
Didn’t Bugs Bunny get targeted as a Hossenfelder dinner in one of the old episodes?
Elon Musk must have been having a bad day when he called it the Hyper Loop. If he'd been on form he would have called it something exciting, unique and enigmatic like "X".
I appreciate science news from a scientist. Thank you for the channel.
Based on the effects this discovery would generate, they don't deserve the Nobel Prize. They deserve something else entirely. This could very well change the course of human history.
Apparently, it's been verified by 2 separate labs now. it works.
Do we have scientific verification *without* Chinese characteristics ?
Not really verified, but different labs have had some interresting results, I think more patience is needed, one thing is sure, this material have some interresting properties that are worth studying closer. We need patience and I think this room temperature SC structure is very hard to make consitently, they made it first by mistake in 1999! and spend until now trying to refine the method for making it reliably. They didn't even succeed, but drama lead to early release of the material.
Jesus. Forget the Nobel prize. This would change civilization. People would remember these guy's names after everyone's forgotten about the Nobel prize
Breakthroughs rarely happen, if at all. When someone says they have massively improved something it usually means either they have not, or the marketing department has gotten ahold of the announcement and is making a huge deal out of something that"s actually smaller, and has taken years to accomplish with small improvements every year.
First synthesized in 1999, then sitting on it for 24 years...what?
Love for LK-99 to live up to the hype! Still skeptical but those electron channels remind me of some of the work done by Brown and MIT involving twisted multilayer graphene. ^.^
“This method is faster than conventional 3D printing.” 😂 *Everything* is faster than conventional 3D printing.
Sabine does interesting science and some pretty good humor.
Her deadpan delivery of humor makes me laugh out loud! So enjoyable!
German humor is no laughing matter.
Big if true. Can't wait to watch the video and find out what your take is. If it's true though .... Holy mackerel
It seems legit to me, because even if the floating magnet is turned around, and pushed back into the original position, it floats again. That means the magnetic field of the base isn't fixed, but induced by the floating magnet on top. One side of the magnet is heavier, that explains why the heavy side touches the surface (it's too heavy to float). Maybe they made the video in a hurry and this was the best magnet they could find that was strong enough to float. Well, we'll see what happens in the future.
yea, butt.. the piece is deformed.. glue a little magnet on the backside.. free energy
Superconductors exhibit perfect diamagnetism. They don't necessarily exhibit flux pinning. Those are two separate phenomena, so the piece needing to be in contact to avoid sliding off is not proof that it's not a superconductor.
Yes, thank you Sabine for the word "Daimagnetic". I knew instantly from the video of the half-baked piece of magnet trying to levitate did not pass the bar. Why can't we just build a super AI computer and ask for the right formula if we promise to worship it forever? We need more power, just like we need more coffee & tea!!!
It's pyrolytic graphite, and people should had it reproduced today, nobody did, everyone that tried failed and are checking for any error before they call it debunked.

Great show!
3:14 It's plain Korean, what's so difficult about it?
It's called a hyperloop because it's being built because of hype, as opposed to because it's a reasonable use of resources. It's a trend in technobabble circles, especially in Musk-adjacent projects.
And each company that develops a prototype is looping back to square one. As if maglev technology doesn't already exist, for one obvious example. Just don't tell the investors! 😏
hyperloop is such joke
I love this format! I hope you keep it up :)
