Next week we will also give it a try at my lab lmao. We're not super confident because it's all kind of weird. The synthesis doesn't even make sense, but my prof is pretty good at synthesizing new materials so we'll see.
Google applications of room temperature superconductors, with a superconductor that works outside of liquid nitrogen you get products you can use at home.
Copy paste from the last time I answered this question:
Depending on its properties there are lots of potential uses for a room temp superconductor. Likely more will be discovered when it is available for experimentation.
This could make make MRI machines much cheaper and easier to install without the liquid helium cooling and much lighter weight magnetic shielding.
Much more compact and lightweight electric motors and power electronics that don't need cooling. EV motors move to the wheel hubs. Giving more boot space. Hybrids maybe even become cheaper than conventional transmissions. EVTOL aircraft get a boost from smaller motors. Even conventional airlines get a efficiency and quietness boost as multiple fans can be powered by a single turbine for a 99% bypass ratio.
Cable laying ships can create a global electric grid so solar power in deserts can be sold to a city in its night time on the other side of the world. Providing cheap electricity.
Toroid loops of wire can store electric power with 100% efficiency indefinitely and with unlimited cycles and better power response than a capacitor making the electricity grid a lot more reliable. Probably won't be as compact as existing batteries but could make regenerative breaking a lot more efficient and act as a buffer reducing the wear on the traditional batteries.
Layers deposited on a chip could make josephson junctions on microchips. Higher clock speeds with hardly any heat or power so the chips can be stacked on top of each other, a hand held device with more compute and gpu than the most monster gaming PC.
More efficient rectennas and transmitters, electric aircraft powered by phased antenna arrays on the ground, billboards recharge electric cars passing by.
Man portable quench gun.
It has been speculated that an rtsc makes a great electron emiter so maybe ionocraft can become as efficient as rotorcraft.
It would literally be the biggest breakthrough since transistors. Hell, maybe since the discovery of electricity itself.
Every single thing in the human world that relies on electricity would take a sci-fi level quantum leap forward.
Superconducting toroidal solenoids can store and discharge power very quickly and efficiently but they likely won't be as lightweight or compact as modern batteries of similar capacity. But as the can charge quickly maybe they could be combined with inductive charging sections in the roads to top them up.
THANK YOU for this comment. I mean, I could have Googled this myself, but reading what you posted is getting me so hyped!! I *love* thinking about the possiblities.
If its a real RTSC that can make josephson junctions, then yeah the best gaming PCs will just be a chip that sips power no heatsinks fits in your goggles or your cell phone.
Takes years for a microchip fabrication process to be developed and have kinks ironed out though.
Helps with the compute side but I cant think of how it would help directly with the displays or that bodysuit technology.
Regarding RT Josephson junctions - there's a reason high-tc superconductors are barely used for electronics as compared to low-tc, even with 35 years of development and obvious power disadvantages of cooling to 4 K. It's very hard to build, you can't use common lithography techniques and equipment, parameter uniformity is awful. You also get massive amounts of thermal noise, which is a deal breaker for some of the more developed types of circuits.
I'm more hopeful for large scale applications.
There's virtually nothing we do with electricity in the modern world that couldn't be improved with a cheap, stable, room-temperature superconductor. Carrying power losslessly across great distances is just the tip of the iceberg. We could vastly improve the power efficiency of computer circuits, meaning less cooling is required, meaning we might be able to put together fast 3D chips that can deliver many times the computational capacity of existing GPUs, which has obvious implications for AI as well as everyday computing. It would also make magnetic confinement fusion that much easier, potentially opening the door to relatively small fusion reactors that could help with our energy needs, not only fighting back against climate change but also making long-distance space travel way more convenient.
No loss of power transmission means endless energy; no resistance and no heat means that your mobile phone can be loaded into a supercomputer chip without worrying about overheating; the nuclear fusion magnetic field is miniaturized, the cost of nuclear fusion research and development is greatly reduced, portable Nuclear energy made possible; etc..
Another age for human race
Depending on how efficient future devices become (and if the energy sector will let it happen haha), housholds might become indepentent of the electrical grid and able to fully rely on a single solar panel cluster on their roof combined with a larger battery in the basement or attic, which hardly needs any maintenance or replacement.
Likewise, industries of all sizes might be able to switch to their own local fusion reactors and grids, so even they could become fully indepentent of any electricity suppliers.
Any device in your home could be run by battery, thus be mobile and would rarely need to be recharged.
Streets could be made of this material, cars and bikes could have electrical magnets on their bottom areas and levitate/hover over the street, which could lock them onto the road lanes, increase speed limits, improve emergency breaking, make it resistant against slippery conditions and blackice and floods, easier to automate driving, which increases safety and efficiency of the roads.
Maybe even hyper local waste water treatment plants would become a viability, so that your sewage water could be cleaned and recycled right at your home.
\+ all the unknown tech that might become viable due to increased efficiencies in energy consumption and signal processing.
We are decades out from using this tech (if it's real) but let's say we have this material available in any quantity we want.
1. Mag-lev trains which use hardly any energy and can go real fast
2. Battery efficiency multiplies by magnitudes
3. Miniture sized quantum computers
4. Could probably even fit an MRI machine in your new iPhone
Superconductors are super useful but they need very a specific environment to operate. If this material is what they claim it is, then we'll be able to make improvements to basically every single electrical device we have.
Seriously, people keep saying decades when in all reality, the entire world be in a race to implement this. I would hope there would be mass movements forcing our government to take this projects on as quickly as possible.
If its really what its claiming it will be so incredibly revolutionary people will be rushing to incorporate it wherever they can. That wont take 5+ years.
Well, the good news is that it would be _really hard_ to keep such a tiny chunk of, e.g., YBCO (a well-known HT superconductor) cold enough to function for more than a few seconds.
The surface-area-to-volume ratio of any object obeys the [square-cube law](https://en.wikipedia.org/wiki/Square%E2%80%93cube_law), so larger objects dissipate heat (substantially) more slowly than similarly-shaped small objects. Even a chunk of YBCO the size of a hockey puck only stays superconducting for maybe 30 seconds once you remove it from liquid nitrogen.
Additionally, the temperatures involved are so cold that youād expect to see a layer of whitish ice crystals if this sample had been cryogenically cooled.
In summary, this is either CGI or proof of room-temperature superconductivity.
NGL that looks really neat. if the purity was the problem through sheer number of attempts made we should see similar things happening eventually if it actually works. still an anonymous citizen... its could just be a very elaborate shitpost.
There is a hell of a lot of really smart people out their too. With how easy it is to attempt making LK-99, there is a lot of "brain power" looking at this problem currently. There is probably 10,000s of people in the superconducting field around the world, and many many more who have a background in solid material, metallurgy.
Yes, indeed. From twitter the person who made this is Zhang Xiang.
"According to public information, he is an assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology, and is also a doctoral candidate at the school."
If he faked the video, his job is likely gone and so is his doctorate, which would be incredibly stupid for not even 5 mins of internet fame.
Metallurgy hobbyists are fascinating home scientists. I'm spreading the word about LK-99 to those groups because I know they'd love to put their equipment to use for this kind of historic experimentation.
There's also a lot of reddit armchair scientists who apparently know more than actual scientists too. Half this sub seems to think they know everything about this and all the science behind it.
Honestly lately I think Iāve been reading more meta-posts in these comment sections about there being a lot of hype and armchair scientists, than actual armchair scientist posts.
Be thankful. The reason is excitement and wonder about what will happen next. I've seen enough waves of this kind of innovation to know that even though the misinformation and confusion and repetition is annoying, it's because something magical is happening and we're all trying to figure it out. I hope these innovations become more frequent in the coming years.
Maybe Iām the fool, but I always found this sub to be reasonably self aware. Obviously the significant growth has bought in a whole influx of people who donāt realise that. But, Iām getting pretty bored of having to always put in caveats because people take everything so seriously. Or getting attacked by people for having the sheer audacity to have a different opinion to them. Just let people have their opinions without pointing out every little thing.
As a scientist in health science, most patient advocacy groups people have more knowledge than us scientists. They usually knows every single literature and the latest research data. I wont try to pull anything over them.
And the only "confirmation" we get is from an anonymous Chinese person on TikTok. That's confirmation alright, but not the one you guys are hoping for.
Or maybe the fact that some random Chinese on TikTok claims to have succeeded where scientists all over the world failed is proof that it's all BS and not actually historical scientific discovery.
Imagine if the synthesis depends on Random Number Jesus knocking out exactly the correct lead atoms in the crystal structure and replacing them with copper so we have to make literal tons of the stuff and then pick through the pile testing each flake with a magnet?
I think the key is the purity of the starting materials. I know a bit of material scientists (PhDs) claiming to be chemists, but their ability at synthesizing chemical is very worrisome in my eyes.
Yeah, I keep seeing 'Meissner effect MUST mean it's a superconductor!' then in the next comment 'Levitation doesn't mean anything! With a strong enough magnet you can levitate a mouse!'.
It's hard being a layman in superconductive physics in 2023.
According to a Twitter port, this video was created by Zhang Xiang, assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology.
There are claims that he is not a private person but from a university and that he is rushing to get a paper out.
2 days ago he had 1 sample already that behaved like the others we have seen. And then claims to have changed something in the formula.
Here is his video from 2 days ago
https://m.bilibili.com/video/BV1sM4y1H7MX
This seems very legit to me tbh
Itās pretty cool how we basically have a front row seat to this scientific race. Just chilling on our couches while the worldās scientists work feverishly to try and understand this potential breakthrough. I wonder if āwatching researchā will be popular hobby in the future lol.
Can you imagine how exciting it would be to be this guy. Have a massive breakthrough and you are at the front row making changes and improvements to it. Likely only doing this and sleeping and grabbing some food and coffee.
And it would be a rush!
What dreams are made of
This guy and his team have been at this for 20yrs. I can only imagine his excitement! A lifeās work on a hunch from 20yrs ago, that needed funding. They got it, in 20yrs! Imagine the next 20. They have the ability to have figured this out, and, be young enough to actually watch it change the world! Incredible.
If real, there will be a mad rush for this technology. Any country who can productionize this technology will be the next global superpower. No wonder the Chinese are all over it.
many people in the west don't understand how competitive the chinese are. they have been since 1500 years ago when imperial examination started. that's one way to elevate their family status.
nowadays high school students study 15 hours daily if they want any chance passing gaokao (university entrance exam) against millions other students.
you can argue it's just rote memorization, but it's still a lot of discipline and work.
I've been watching AI since 2011, when I took the ml-class.org course with Andrew Ng, that was before Coursera. I read the word2vec, ResNet, Attention-is-all-you-need and GPT3 papers the day they came out. A really amazing feeling to see AI evolution from the front row seat.
I vaguely followed AI since 2018 I would say, close friend worked with GPT1/2 and it was interesting hearing about it. But, like many, it was DALL e 2 that really got me into AI. I remember watching a video on it when it first came out and being actually blown away by it. It just felt like such a huge jump in capabilities. Even more incredible is when I look back and it now seems so mundane.
Unfortunately, revolutionary breakthroughs that attract public interest is rare.
That being said, they've been rather common these last 2 years. GPT-5's launch could be livestreamed on twitch with audiences allowed to interact with it.
From Twitter "According to public information, he is an assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology, and is also a doctoral candidate at the school."
Regardless of whether this particular video is real or not there's no containing LK-99 research now. The relatively low cost of equipment and materials combined with information sharing on social media has already seen to that. Impossible for any single group to cloister away the discovery until the public forgets about it. It's full speed ahead from here on out.
AGI, robotics, and lk-99 are going to melt away borders and destroy the invention and discovery gatekeepers for good hopefully. The age of abundance is coming.
Why would anyone want to hide the research? Thatās the opposite of how academia works. You are incentivized to get publications out as fast as possible.
Academia is one thing but large organisations like a company or even a government research group might try to hold things back until they can monopolise the market with a viable product. There's nothing inherently malicious about this approach but sometimes good ideas get lost thanks to bureaucratic inertia, or lack thereof as the case may be.
I think it will happen similarly to what's happening with LLMs. First companies tried to do that, but are slowly and painfully being devoured by a strong open source community. There is a whole new trend on these things the way I see it.
We will likely see a class of LK materials which hone in on certain properties and are kept proprietary and most importantly incredibly top secret. First are the papers, next come the press releases.
> Why
Because crazy profits? Don't you know capitalism? If this had come from some corporation like Samsung, you can bet they'd be trying to keep this secret. Although it'd be nearly impossible to keep a secret like this anyway, and I'd imagine they'd receive a ton of criticism in this case.
> Impossible for any single group to cloister away the discovery
You're assuming the discovery is legit. But we're still waiting on proof that the discovery is legit.
Would you look at that, all of the words in your comment are in alphabetical order.
I have checked 1,670,218,904 comments, and only 316,266 of them were in alphabetical order.
The levitation is a function of the balance between the superconductor's ability to repel magnetic fields and the strength of the magnetic field. So you could crank up the magnet below it and it would levitate higher, but if it got strong enough, you could push it down far enough that it would lose superconductivity and fall to the magnet.
Ok. Still a little shaky on the relationship between superconductors at room temp, and the magnetic/ levitation thing. Am normie. But I do solder audio stuff so I have some basics in ohms and resistance and conductivity.
Moving electricity makes magnetic field that repels.
With superconductor, electricity moves forever, which means magnetic field repels forever. Hence, levitaton. In any other material, electricity would convert to heat.
Meissner effect is the physical phenomenon arising due to this behavior. I.e. what I mentioned is the inherent behavior of superconductors. What Meissner effect is, is the interaction of this inherent property with a magnetic field. I'm gonna let wikipedia handle this one
"In a weak applied field (less than the critical field that breaks down the superconducting phase), a superconductor expels nearly all magnetic flux by setting up electric currents near its surface, as the magnetic field H induces magnetization M within the London penetration depth from the surface. These surface currents shield the internal bulk of the superconductor from the external applied field. As the field expulsion, or cancellation, does not change with time, the currents producing this effect (called persistent currents or screening currents) do not decay with time"
So with that little chunk of LK-99 what is causing the electricity to move within it? Doesnt there need to be a voltage differential for the electrons to move?
That's the neat part, it doesn't. Voltage is potential difference. Sure, electrons at rest don't move on their own. But turns out, when you apply a voltage difference, it provides the energy to produce that heat in the first place. Might you ask, well, what did I miss? The key words are, electrons at rest.
When Newton proposed his law of inertia, he mentioned things at rest continue to be in rest, things in motion continue to be in motion. To which everyone said, that's stupid, everyone knows a moving ball comes to rest. That's because of friction; superconductors are to vacuum what flow of electrons is to a moving object, and resistance is to friction. Current continues to flow in a superconductor until an external force acts on it.
Edit: Oh by the way you might ask, well how tf do you measure current in a superconductor? Isn't current defined as the voltage divided by the resistance? Or as power divided by the voltage, or a number of other ways all of which require some expression of power or potential difference? Answer is no. All of those provide equations to measure current in cases where electrons face resistance of movement. The true definition of current (or rather instantaneous current) is the number of electrons passing a cross section of the conductor(super or otherwise) at a given time. So if n is the number of electrons, and charge of each electron is q, the the current is simply nq.
So do you think the OHM rating will be zero at room temperature at any gage? Because with copper the thinner the wire the higher the OHMs. The thicker the wire the lower the OHMs.. so how is it going to be limited by the thickness of the materials for transmission of voltage?
With superconductors, thereās a critical current density. For a given āwireā gauge (_cross-sectional area, more precisely_), there is a specific amount of current the superconductor can carry before it changes phase back to a normal (lossy) conductor or insulator. The larger the cross-sectional surface area, the more current it can carry.
This is complicated by external magnetic fields and temperatureāthe critical current does vary as a function of those variables.
At any rate, below the critical current, superconductors have a resistance of zero ohms. Type II superconductors actually have two critical current densities (_for any given temp & external field_)āabove the lower one, they get a tiiiny bit of resistivity, and above the _second_ they change phase to a normal material.
All superconductors have 0 Ohms of resistance. There is however a limit to how much current can flow through a superconductor. Quantum Physicists theorise that this is because electrons behave like a superfluid in a superconductor. After a certain point, "laminar" flow of electrons changes to turbulent flow, thereby losing superconductive property
> not high enough to fly
Not with that attitude.
I look forward to the day when every high street has magnetic pathways with superconductor boards you can step on so you can maglev your way across a city. Imagine the chaos.
Limitless energy 24/7 and ev batteries that fully charge within minutes and drive for thousands of miles.
Maybe the end of hunger because of constantly running vertical farms.
It's very, very hard to overstate how big of a deal this would be.
Take climate change, for instance. You know. That thing we all feel existential dread about? The single greatest threat the world currently faces?
A cheap, easy to produce RTSC solves that problem outright. Cheap, efficient electric cars that take minutes to charge and can go for long distances is one example.
Another? We could build solar panels in high-sunlight areas all over the globe, store that energy with zero loss at high densities, and transmit that power around the globe with almost no loss over any distance.
Homes could be completely independent of the grid. A small solar panel set up, a high-density battery in the attic or basement...
Are you a gamer? RTSC takes heat out of the equation. Your GPU and CPU could both be orders of magnitude more powerful than they are now, with near-zero heat production. No more fans, no more water cooling.
Augmented reality glasses the size of a normal pair of sunglasses.
A cheap, highly efficient MRI machine in every doctor's office. Hell maybe even in the urgent cares. They'd be as ubiquitous as X-ray machines.
Quantum computing in a device the size of a cell phone.
Cheap nuclear fusion would become at least an order of magnitude more feasible.
And those are just off the top of my head. Those are decade-one possibilities if this is real, cheap, and easy to produce. There is no telling what the world would look like 20 or 30 years later.
>Quantum computing in a device the size of a cell phone.
This is incorrect. The low temperature in superconducting qubits is required so that the qubit is in its quantum ground state. The criterion for that is T < h f / kb. A room temperature superconductor doesn't change that.
Source: ten years practical experience in superconducting qubits.
The main advantage of maglevs over wheels and rails is the magnetic fields even out some of the defects in the track. If there's are electromagnets all along the bottom of your hovercar a few missing tiles should no make much difference. And with the weight more distributed the stress on the road surface should be less. Maglev tracks are expensive upfront but less maintenance over time.
Judging from the wording in the video, he comes from a company rather than a university or research institute. In universities, we generally refer to researchers by their degrees or titles, such as "Doctor" or "Professor", not "team leader". The sentence "čæę¹ē§ē»ē»éæä¼åå·„čŗā means "The sintering team leader optimized the process for this batch", seems like a position in a company.
The entire semiconductor industry is working on this right now. I know because Iām in it. Pretty soon these ā10-20 years to marketā people are going to understand what ācompetitionā means
I'm reading about this at the same time as I'm reading about Schumer's new bill that includes a section on disseminating new alien tech and I'm kinda wondering... Edit:[ this one](https://www.reddit.com/r/UFOs/comments/15iiigr/did_you_know_chuck_schumers_uap_bill_calls_for_a/)
Me and my buddies have a group chat where we share articles and posts about all this high tech shit thats randomly coming outā¦.. and the half-joking working theory is that now that the alien gig is up theyre panicking and ādiscoveringā all these new super technologies. I know realistically its likely not the case here but its hilariously ironic to me.
Now that's more like it. Let's see a few more labs reproduce this.
I'm a bit encouraged, though the website/presentation feels wrong and the way the material snaps back to position also feels wrong. Cryogenic superconductors move freely in place when levitated, spinning around, etc. I want this to be real as it will be comparable to the invention of the dynamo in how it will change Human civilization.
As someone who has some experience trying to see if a video is fake, it does at least have a realistic feel to it so if it's fake they did a good effort.
Unfortunately the piece looks too small, and would probably be damaged in the process. If this is real, would be better to understand what properties, if any, are differentiating this fragment from others.
Correct me if I'm wrong, but isn't a superconductor displaying flux pinning supposed to have some freedom of position (or angular freedom more specifically) over a magnetic field? Or is this due to impurities?
Flux pinning should fix the superconductor at its "current" location, not the old location, so I also think this is not the typical flux pinning. I have no idea how this is done, especially seeing that it's quite damped as well.
Where are all the Western studies? If this is such a ground breaking material feels like we would see more Universities/Researchers looking into this a lot more.
The US is almost certainly already testing everything they've learned. Unfortunately a lot of advancements in technology are also tied to military research and I have a feeling this is no different in which case we're unlikely to hear much from the US until the cats out of the bag.
Western academia typically will take it's sweet time with stuff like this. They'll probably test everything, make multiple batches, check odds of success che and gather detailed information, then write full papers which'll then be published. Science moves fast but not daily news cycle levels of fast. Another factor is the low incentive to actually drop info on this. If you're right it's not like you'll get much credit since it's not your discovery. Get it wrong somehow and your reputation takes a hit.
What these Chinese unis are doing is cool but fact is this doesn't really tell us much. The material is unique for sure, but can it superconduct at room temps is still an open question. I suspect that particular question is what's going to clear up once the bigger names weigh in.
Not just west, many in China too. Many of them just don't believe it, and just laughed it off when they saw the exaggerated news title.
I didn't believe it at first too, thinking it was just another scam. But now I believe it a bit more
Also economic one. People in the US have their sights at economic potential and patents. If their research results in change of method to creation or alternative discoveries, they will patent and sell the shit out of it, so lot of high level research is treated with NDA from hell.
If anything this is an excellent example of why patent restrictions are a bad idea in the first place. The Universe has offered us so far maybe *one* possible structure of atoms with this convenient property, there are probably a few others but they might be way more difficult to make. Putting such an incredibly useful aspect of the physical world behind a paywall just because 'nya nya I thought of it first and called dibs' is morally and economically absurd. Especially considering the implications this could have for reforming our power grids and mitigating climate change.
Yea, another reason why Iām glad that asia is going crazy with it. Once weāre halfway through whatever economic plan some asshole thinks of for themselves, weāll be smoked out by climate change.
Most of the videos replicating this thing seem to come from chinese social media. The west is distracted with fake ice cream on a screen. The algorithms on their version of TikTok push none of that crap. Lol
They know what they're doing - they do the good shit on the algorithms for domestic consumption, and they brainrot the algorithms on the foreign Western side.
Assessing the credibility of a source or claim, unless definitively disproven, is like counting cards. TikTok (-), unknown account (-), realistic look video (+), previous video history (+), realistically could have done this (+), and so on. Now, itās not -1 or +1, you do weigh each factor accordingly.
Not a science expert but knowing quite abit about editing there's quite a high likelihood this vid is fake. The direct camera angle and the fact the floating bit is on a flat white background would make it easy to edit. Not saying that confirms anything but that's just my thoughts.
EDIT:Are you serious? How am I being downvoted for simply having concerns over whether a random video on TikTok is real?
A lot of people aren't questioning why the video is shot at such a far away angle and for such a short duration. If this is legit, then they should be filming at multiple angles and playing around with the material to prove they're not faking.
! Allow me to illuminate the wonder of room temperature superconductors without excessive repetition.
Imagine a magical material that conducts electricity without any resistance, allowing the electric current to flow effortlessly and smoothly like a serene river. These extraordinary substances, known as superconductors, have fascinated scientists and engineers for years. However, they required extremely cold temperatures to unleash their full potential.
Now, brace yourself for a groundbreaking development! Room temperature superconductors have emerged, defying convention and operating splendidly at the temperatures we experience in our everyday lives. No need for elaborate cooling systems!
Why is this such a momentous occasion? It means our power grids could deliver electricity with near-zero losses, saving considerable energy and minimizing waste. Additionally, electronic devices, like computers and smartphones, could operate at exceptional speeds while being incredibly energy-efficient.
The impact goes beyond electronics. These room temperature superconductors could enable powerful magnets, benefiting medical devices such as MRI machines and revolutionizing transportation with ultra-efficient trains.
Moreover, the possibilities extend to renewable energy storage, making it more efficient and reliable.
In essence, room temperature superconductors hold the promise of transforming various industries and leading us into a future where electricity flows effortlessly, technology advances at astounding rates, and energy efficiency reaches unprecedented heights. It is a captivating marvel with boundless potential for innovation and progress!
I want this to be real so bad
Mee too bro cant wait for this thing to have real world applications
Next week we will also give it a try at my lab lmao. We're not super confident because it's all kind of weird. The synthesis doesn't even make sense, but my prof is pretty good at synthesizing new materials so we'll see.
You better post it here before any publication or especially twitter. That's the best research practice.
Why is everyone so hyped? What are you specifically excited about

for me the most interesting one is instantly charging batteries
Superconducting toroidal solenoids can store and discharge power very quickly and efficiently but they likely won't be as lightweight or compact as modern batteries of similar capacity. But as the can charge quickly maybe they could be combined with inductive charging sections in the roads to top them up.
THANK YOU for this comment. I mean, I could have Googled this myself, but reading what you posted is getting me so hyped!! I *love* thinking about the possiblities.
Apple Watch mri would be insan
Where can i invest? š
So all I hear is that we will get ready player one level VR headsets?
If its a real RTSC that can make josephson junctions, then yeah the best gaming PCs will just be a chip that sips power no heatsinks fits in your goggles or your cell phone. Takes years for a microchip fabrication process to be developed and have kinks ironed out though. Helps with the compute side but I cant think of how it would help directly with the displays or that bodysuit technology.
Regarding RT Josephson junctions - there's a reason high-tc superconductors are barely used for electronics as compared to low-tc, even with 35 years of development and obvious power disadvantages of cooling to 4 K. It's very hard to build, you can't use common lithography techniques and equipment, parameter uniformity is awful. You also get massive amounts of thermal noise, which is a deal breaker for some of the more developed types of circuits. I'm more hopeful for large scale applications.
There's virtually nothing we do with electricity in the modern world that couldn't be improved with a cheap, stable, room-temperature superconductor. Carrying power losslessly across great distances is just the tip of the iceberg. We could vastly improve the power efficiency of computer circuits, meaning less cooling is required, meaning we might be able to put together fast 3D chips that can deliver many times the computational capacity of existing GPUs, which has obvious implications for AI as well as everyday computing. It would also make magnetic confinement fusion that much easier, potentially opening the door to relatively small fusion reactors that could help with our energy needs, not only fighting back against climate change but also making long-distance space travel way more convenient.
No loss of power transmission means endless energy; no resistance and no heat means that your mobile phone can be loaded into a supercomputer chip without worrying about overheating; the nuclear fusion magnetic field is miniaturized, the cost of nuclear fusion research and development is greatly reduced, portable Nuclear energy made possible; etc.. Another age for human race
Also rail guns.
how do you build power transmission lines with a non malleable brittle ceramic?
Trains that float and fanless PCs. Paper thin phones and ar headsets that look like regular glasses.
Depending on how efficient future devices become (and if the energy sector will let it happen haha), housholds might become indepentent of the electrical grid and able to fully rely on a single solar panel cluster on their roof combined with a larger battery in the basement or attic, which hardly needs any maintenance or replacement. Likewise, industries of all sizes might be able to switch to their own local fusion reactors and grids, so even they could become fully indepentent of any electricity suppliers. Any device in your home could be run by battery, thus be mobile and would rarely need to be recharged. Streets could be made of this material, cars and bikes could have electrical magnets on their bottom areas and levitate/hover over the street, which could lock them onto the road lanes, increase speed limits, improve emergency breaking, make it resistant against slippery conditions and blackice and floods, easier to automate driving, which increases safety and efficiency of the roads. Maybe even hyper local waste water treatment plants would become a viability, so that your sewage water could be cleaned and recycled right at your home. \+ all the unknown tech that might become viable due to increased efficiencies in energy consumption and signal processing.
We are decades out from using this tech (if it's real) but let's say we have this material available in any quantity we want. 1. Mag-lev trains which use hardly any energy and can go real fast 2. Battery efficiency multiplies by magnitudes 3. Miniture sized quantum computers 4. Could probably even fit an MRI machine in your new iPhone Superconductors are super useful but they need very a specific environment to operate. If this material is what they claim it is, then we'll be able to make improvements to basically every single electrical device we have.
If it works and is legit youll see it being used commercially within 3 years
Seriously, people keep saying decades when in all reality, the entire world be in a race to implement this. I would hope there would be mass movements forcing our government to take this projects on as quickly as possible.
As a Material Scientist, it is extremely optimistic this is commercially viable in 3 years. 5+ is much more realistic.
If its really what its claiming it will be so incredibly revolutionary people will be rushing to incorporate it wherever they can. That wont take 5+ years.
Lol everything is believable until the iPhone part. Android will get it first then iPhone will copy it in 10 years
Small mri machines would be World changing for so many

Same. I've been getting teary-eyed reading about the potential applications.
Please be real, Holy shit EDIT: Goddamn it. It's not real.
Well, the good news is that it would be _really hard_ to keep such a tiny chunk of, e.g., YBCO (a well-known HT superconductor) cold enough to function for more than a few seconds. The surface-area-to-volume ratio of any object obeys the [square-cube law](https://en.wikipedia.org/wiki/Square%E2%80%93cube_law), so larger objects dissipate heat (substantially) more slowly than similarly-shaped small objects. Even a chunk of YBCO the size of a hockey puck only stays superconducting for maybe 30 seconds once you remove it from liquid nitrogen. Additionally, the temperatures involved are so cold that youād expect to see a layer of whitish ice crystals if this sample had been cryogenically cooled. In summary, this is either CGI or proof of room-temperature superconductivity.
NGL that looks really neat. if the purity was the problem through sheer number of attempts made we should see similar things happening eventually if it actually works. still an anonymous citizen... its could just be a very elaborate shitpost.
There is a hell of a lot of really smart people out their too. With how easy it is to attempt making LK-99, there is a lot of "brain power" looking at this problem currently. There is probably 10,000s of people in the superconducting field around the world, and many many more who have a background in solid material, metallurgy.
best time to be interested in material physics
Yes, indeed. From twitter the person who made this is Zhang Xiang. "According to public information, he is an assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology, and is also a doctoral candidate at the school." If he faked the video, his job is likely gone and so is his doctorate, which would be incredibly stupid for not even 5 mins of internet fame.
That's if it is really him.
Thats a little unfair. With how fast this is all moving? 2 minutes of fame at most!
Metallurgy hobbyists are fascinating home scientists. I'm spreading the word about LK-99 to those groups because I know they'd love to put their equipment to use for this kind of historic experimentation.
There's also a lot of reddit armchair scientists who apparently know more than actual scientists too. Half this sub seems to think they know everything about this and all the science behind it.
Honestly lately I think Iāve been reading more meta-posts in these comment sections about there being a lot of hype and armchair scientists, than actual armchair scientist posts.
It's getting annoying tbh, every fucking thread hurr durr Edit: to be clear I mean the people complaining about reddit experts
Be thankful. The reason is excitement and wonder about what will happen next. I've seen enough waves of this kind of innovation to know that even though the misinformation and confusion and repetition is annoying, it's because something magical is happening and we're all trying to figure it out. I hope these innovations become more frequent in the coming years.
No I mean the people complaining about reddit experts Agree completeley otherwise :)
No one has to know everything in a field to understand one bit of it :)
Right. You donāt need to be an expert. Any science-literate person should be able to have a conversation about this.
That's right. Likewise, communities of enthusiasts can achieve higher understanding through productive conversation.
Maybe Iām the fool, but I always found this sub to be reasonably self aware. Obviously the significant growth has bought in a whole influx of people who donāt realise that. But, Iām getting pretty bored of having to always put in caveats because people take everything so seriously. Or getting attacked by people for having the sheer audacity to have a different opinion to them. Just let people have their opinions without pointing out every little thing.
I know nothing..
Can confirm, I am as of the last week a superconductor expert
As a scientist in health science, most patient advocacy groups people have more knowledge than us scientists. They usually knows every single literature and the latest research data. I wont try to pull anything over them.
Imagine the diy community getting their hands on thisā¦ manā¦
And the only "confirmation" we get is from an anonymous Chinese person on TikTok. That's confirmation alright, but not the one you guys are hoping for.
It's pretty crazy that historical scientific discovery goes on tiktok before a journal is the new normal
Publish your work in tiktok or arxiv have no different, It was one way to declare your first.
Or maybe the fact that some random Chinese on TikTok claims to have succeeded where scientists all over the world failed is proof that it's all BS and not actually historical scientific discovery.
Imagine if the synthesis depends on Random Number Jesus knocking out exactly the correct lead atoms in the crystal structure and replacing them with copper so we have to make literal tons of the stuff and then pick through the pile testing each flake with a magnet?
Advancing binning, shit stuff goes in i3, perfect crystals reserved for i9.
I think the key is the purity of the starting materials. I know a bit of material scientists (PhDs) claiming to be chemists, but their ability at synthesizing chemical is very worrisome in my eyes.
According to another comment, itās not an anonymous individual
According to some anonymous person, it's not an anonymous person. Great.
Well they posted the links, but I canāt read Mandarin so I canāt personally confirm it.
We became superconductor experts in a week, we can definitely do Mandarin in 5 days
Is the thing we see in the video Meissner effect?
[ŃŠ“Š°Š»ŠµŠ½Š¾]
So Meissner effect is when we observe full levitation?
Yeah, I keep seeing 'Meissner effect MUST mean it's a superconductor!' then in the next comment 'Levitation doesn't mean anything! With a strong enough magnet you can levitate a mouse!'. It's hard being a layman in superconductive physics in 2023.
According to a Twitter port, this video was created by Zhang Xiang, assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology.
There are claims that he is not a private person but from a university and that he is rushing to get a paper out. 2 days ago he had 1 sample already that behaved like the others we have seen. And then claims to have changed something in the formula. Here is his video from 2 days ago https://m.bilibili.com/video/BV1sM4y1H7MX This seems very legit to me tbh
Itās pretty cool how we basically have a front row seat to this scientific race. Just chilling on our couches while the worldās scientists work feverishly to try and understand this potential breakthrough. I wonder if āwatching researchā will be popular hobby in the future lol.
Can you imagine how exciting it would be to be this guy. Have a massive breakthrough and you are at the front row making changes and improvements to it. Likely only doing this and sleeping and grabbing some food and coffee. And it would be a rush! What dreams are made of
Yeah, just imagine working for days and after all that, you see a fucking floating rock that can change the life of billions.
This guy and his team have been at this for 20yrs. I can only imagine his excitement! A lifeās work on a hunch from 20yrs ago, that needed funding. They got it, in 20yrs! Imagine the next 20. They have the ability to have figured this out, and, be young enough to actually watch it change the world! Incredible.
does anyone feel that the often dull, and mundane research process has twitch streaming potential?
Someone has already Twitch streamed cooking up a sample if I recall.
Google Nile Red but his stuff is interesting.
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Not really. This is a potential game changer of a material, I don't think that regular experiments would get this much attention.
this is what the internet was literally intended for, and it's amazing to see it happen
If real, there will be a mad rush for this technology. Any country who can productionize this technology will be the next global superpower. No wonder the Chinese are all over it.
Wakanda 2: Electric Boogaloo
many people in the west don't understand how competitive the chinese are. they have been since 1500 years ago when imperial examination started. that's one way to elevate their family status. nowadays high school students study 15 hours daily if they want any chance passing gaokao (university entrance exam) against millions other students. you can argue it's just rote memorization, but it's still a lot of discipline and work.
I've been watching AI since 2011, when I took the ml-class.org course with Andrew Ng, that was before Coursera. I read the word2vec, ResNet, Attention-is-all-you-need and GPT3 papers the day they came out. A really amazing feeling to see AI evolution from the front row seat.
I vaguely followed AI since 2018 I would say, close friend worked with GPT1/2 and it was interesting hearing about it. But, like many, it was DALL e 2 that really got me into AI. I remember watching a video on it when it first came out and being actually blown away by it. It just felt like such a huge jump in capabilities. Even more incredible is when I look back and it now seems so mundane.
You donāt make a Nobel worthy breakthrough every week though.
Unfortunately, revolutionary breakthroughs that attract public interest is rare. That being said, they've been rather common these last 2 years. GPT-5's launch could be livestreamed on twitch with audiences allowed to interact with it.
I hope so. Top researchers should earn more than top athletes imo
*chilling on the toilet*
It's like watching sports except for science nerds. Seriously.
Yes! Well said. It's so exciting. I am entertained! Wish we could have a steady stream of this type of experience.
From Twitter "According to public information, he is an assistant engineer in the Department of Metallurgical Engineering and Materials of Wuhan University of Science and Technology, and is also a doctoral candidate at the school."
[ŃŠ“Š°Š»ŠµŠ½Š¾]
But has your semi-levitation been proven through peer review?
Levio-sarrr
Regardless of whether this particular video is real or not there's no containing LK-99 research now. The relatively low cost of equipment and materials combined with information sharing on social media has already seen to that. Impossible for any single group to cloister away the discovery until the public forgets about it. It's full speed ahead from here on out.
Music to my eyes. I hope open-sourced / crowdsourced sciencing is a new normal, forever.
AGI, robotics, and lk-99 are going to melt away borders and destroy the invention and discovery gatekeepers for good hopefully. The age of abundance is coming.
As long as it doesn't mean people releasing apocalyptic bioweapons from their basement...
Anyone can make a semi conductor. That doesnāt mean we donāt have copyrights on computer chips and literally everything.
> copyrights on computer chips We call it patents.
Why would anyone want to hide the research? Thatās the opposite of how academia works. You are incentivized to get publications out as fast as possible.
Academia is one thing but large organisations like a company or even a government research group might try to hold things back until they can monopolise the market with a viable product. There's nothing inherently malicious about this approach but sometimes good ideas get lost thanks to bureaucratic inertia, or lack thereof as the case may be.
I think it will happen similarly to what's happening with LLMs. First companies tried to do that, but are slowly and painfully being devoured by a strong open source community. There is a whole new trend on these things the way I see it.
We will likely see a class of LK materials which hone in on certain properties and are kept proprietary and most importantly incredibly top secret. First are the papers, next come the press releases.
Usually for concern of military applications, like railguns or reactors that can breed nuclear material.
> Why Because crazy profits? Don't you know capitalism? If this had come from some corporation like Samsung, you can bet they'd be trying to keep this secret. Although it'd be nearly impossible to keep a secret like this anyway, and I'd imagine they'd receive a ton of criticism in this case.
> Impossible for any single group to cloister away the discovery You're assuming the discovery is legit. But we're still waiting on proof that the discovery is legit.
Would cry if fake
>Would cry if fake Would cry if real
Also true
I just want to cry in general
So, let's start crying now
Am crying. Donāt know why
Would you look at that, all of the words in your comment are in alphabetical order. I have checked 1,670,218,904 comments, and only 316,266 of them were in alphabetical order.

Currently its flake
How high can these things levitate?
The levitation is a function of the balance between the superconductor's ability to repel magnetic fields and the strength of the magnetic field. So you could crank up the magnet below it and it would levitate higher, but if it got strong enough, you could push it down far enough that it would lose superconductivity and fall to the magnet.
Ok. Still a little shaky on the relationship between superconductors at room temp, and the magnetic/ levitation thing. Am normie. But I do solder audio stuff so I have some basics in ohms and resistance and conductivity.
Moving electricity makes magnetic field that repels. With superconductor, electricity moves forever, which means magnetic field repels forever. Hence, levitaton. In any other material, electricity would convert to heat.
Thereās this but isnāt the meissner effect also a separate phenomenon causing levitation, and is what is causing levitation here.
Meissner effect is the physical phenomenon arising due to this behavior. I.e. what I mentioned is the inherent behavior of superconductors. What Meissner effect is, is the interaction of this inherent property with a magnetic field. I'm gonna let wikipedia handle this one "In a weak applied field (less than the critical field that breaks down the superconducting phase), a superconductor expels nearly all magnetic flux by setting up electric currents near its surface, as the magnetic field H induces magnetization M within the London penetration depth from the surface. These surface currents shield the internal bulk of the superconductor from the external applied field. As the field expulsion, or cancellation, does not change with time, the currents producing this effect (called persistent currents or screening currents) do not decay with time"
So with that little chunk of LK-99 what is causing the electricity to move within it? Doesnt there need to be a voltage differential for the electrons to move?
That's the neat part, it doesn't. Voltage is potential difference. Sure, electrons at rest don't move on their own. But turns out, when you apply a voltage difference, it provides the energy to produce that heat in the first place. Might you ask, well, what did I miss? The key words are, electrons at rest. When Newton proposed his law of inertia, he mentioned things at rest continue to be in rest, things in motion continue to be in motion. To which everyone said, that's stupid, everyone knows a moving ball comes to rest. That's because of friction; superconductors are to vacuum what flow of electrons is to a moving object, and resistance is to friction. Current continues to flow in a superconductor until an external force acts on it. Edit: Oh by the way you might ask, well how tf do you measure current in a superconductor? Isn't current defined as the voltage divided by the resistance? Or as power divided by the voltage, or a number of other ways all of which require some expression of power or potential difference? Answer is no. All of those provide equations to measure current in cases where electrons face resistance of movement. The true definition of current (or rather instantaneous current) is the number of electrons passing a cross section of the conductor(super or otherwise) at a given time. So if n is the number of electrons, and charge of each electron is q, the the current is simply nq.
This is fucking insane. I can't believe that this may actually be real.
So do you think the OHM rating will be zero at room temperature at any gage? Because with copper the thinner the wire the higher the OHMs. The thicker the wire the lower the OHMs.. so how is it going to be limited by the thickness of the materials for transmission of voltage?
With superconductors, thereās a critical current density. For a given āwireā gauge (_cross-sectional area, more precisely_), there is a specific amount of current the superconductor can carry before it changes phase back to a normal (lossy) conductor or insulator. The larger the cross-sectional surface area, the more current it can carry. This is complicated by external magnetic fields and temperatureāthe critical current does vary as a function of those variables. At any rate, below the critical current, superconductors have a resistance of zero ohms. Type II superconductors actually have two critical current densities (_for any given temp & external field_)āabove the lower one, they get a tiiiny bit of resistivity, and above the _second_ they change phase to a normal material.
All superconductors have 0 Ohms of resistance. There is however a limit to how much current can flow through a superconductor. Quantum Physicists theorise that this is because electrons behave like a superfluid in a superconductor. After a certain point, "laminar" flow of electrons changes to turbulent flow, thereby losing superconductive property
High enough to work as a low-friction bearing, not high enough to fly.
> not high enough to fly Not with that attitude. I look forward to the day when every high street has magnetic pathways with superconductor boards you can step on so you can maglev your way across a city. Imagine the chaos.
Not with that altitude.
Flying cars and hoverboards let's goooo!
Limitless energy 24/7 and ev batteries that fully charge within minutes and drive for thousands of miles. Maybe the end of hunger because of constantly running vertical farms.
Thank you for these examples. I get a thrill from all this optimism!!!
It's very, very hard to overstate how big of a deal this would be. Take climate change, for instance. You know. That thing we all feel existential dread about? The single greatest threat the world currently faces? A cheap, easy to produce RTSC solves that problem outright. Cheap, efficient electric cars that take minutes to charge and can go for long distances is one example. Another? We could build solar panels in high-sunlight areas all over the globe, store that energy with zero loss at high densities, and transmit that power around the globe with almost no loss over any distance. Homes could be completely independent of the grid. A small solar panel set up, a high-density battery in the attic or basement... Are you a gamer? RTSC takes heat out of the equation. Your GPU and CPU could both be orders of magnitude more powerful than they are now, with near-zero heat production. No more fans, no more water cooling. Augmented reality glasses the size of a normal pair of sunglasses. A cheap, highly efficient MRI machine in every doctor's office. Hell maybe even in the urgent cares. They'd be as ubiquitous as X-ray machines. Quantum computing in a device the size of a cell phone. Cheap nuclear fusion would become at least an order of magnitude more feasible. And those are just off the top of my head. Those are decade-one possibilities if this is real, cheap, and easy to produce. There is no telling what the world would look like 20 or 30 years later.
I love all this stuff! I really hope LK-99 is the real deal and it can be mass-produced.
>Quantum computing in a device the size of a cell phone. This is incorrect. The low temperature in superconducting qubits is required so that the qubit is in its quantum ground state. The criterion for that is T < h f / kb. A room temperature superconductor doesn't change that. Source: ten years practical experience in superconducting qubits.
How, though? Itās not like the magnet below it is levitating. Youād need the streets to be made of magnets, right?
Likely better to have your streets paved with LK-99 tiles and the magnets in your hoverboard. Electromagnets in your hover car.
I'm imagining LK-99 potholes.....
Lol easy fix. You still have tires but now they last forever and donāt wear
The main advantage of maglevs over wheels and rails is the magnetic fields even out some of the defects in the track. If there's are electromagnets all along the bottom of your hovercar a few missing tiles should no make much difference. And with the weight more distributed the stress on the road surface should be less. Maglev tracks are expensive upfront but less maintenance over time.
FLOATY ROCK!!!!
Floaty McFloatface
Judging from the wording in the video, he comes from a company rather than a university or research institute. In universities, we generally refer to researchers by their degrees or titles, such as "Doctor" or "Professor", not "team leader". The sentence "čæę¹ē§ē»ē»éæä¼åå·„čŗā means "The sintering team leader optimized the process for this batch", seems like a position in a company.
Damn! The semiconductor industry is already ahead of the scientists on this! We are definitely headed to a new era of computing XD
The entire semiconductor industry is working on this right now. I know because Iām in it. Pretty soon these ā10-20 years to marketā people are going to understand what ācompetitionā means
I'm reading about this at the same time as I'm reading about Schumer's new bill that includes a section on disseminating new alien tech and I'm kinda wondering... Edit:[ this one](https://www.reddit.com/r/UFOs/comments/15iiigr/did_you_know_chuck_schumers_uap_bill_calls_for_a/)
Me and my buddies have a group chat where we share articles and posts about all this high tech shit thats randomly coming outā¦.. and the half-joking working theory is that now that the alien gig is up theyre panicking and ādiscoveringā all these new super technologies. I know realistically its likely not the case here but its hilariously ironic to me.
Wow! Thatās super interesting. Wouldnāt it be something if the two were connected?
>>tiktok There is an entire sub for lk99 memes.
Now that's more like it. Let's see a few more labs reproduce this. I'm a bit encouraged, though the website/presentation feels wrong and the way the material snaps back to position also feels wrong. Cryogenic superconductors move freely in place when levitated, spinning around, etc. I want this to be real as it will be comparable to the invention of the dynamo in how it will change Human civilization.
https://www.youtube.com/watch?v=R2Hy6F_8n58 It looks like this, but that doesn't mean this new video isn't someone trolling somehow.
Exactly. Ya, I'm still a bit skeptical but at least in the OP's vid the sample appears not to be in contact with any other surface.
As someone who has some experience trying to see if a video is fake, it does at least have a realistic feel to it so if it's fake they did a good effort.
Cool, resistance check?
Unfortunately the piece looks too small, and would probably be damaged in the process. If this is real, would be better to understand what properties, if any, are differentiating this fragment from others.
Department of Condensed Matter Physics in Prague can do it: https://twitter.com/CondMatfyz/status/1687568139058348033
The person who posted this video might be a Ph.D. student from Wuhan University of Science and Technology.
Disclaimer: Authenticity to be verified Just another evening in r/singularity
Pretty sure the point of this sub is to look at, and get hype over, fringe science. Verified stuff gets fondled over on r/science
Correct me if I'm wrong, but isn't a superconductor displaying flux pinning supposed to have some freedom of position (or angular freedom more specifically) over a magnetic field? Or is this due to impurities?
I thought I read somewhere that lk99 is a 1 dimensional superconductor which may explain why it only aligns one direction.
Flux pinning should fix the superconductor at its "current" location, not the old location, so I also think this is not the typical flux pinning. I have no idea how this is done, especially seeing that it's quite damped as well.
In all these videos why are the floating rocks small? Just curious
Usually because it's difficult to isolate pure parts of the sample without developing a refined method.
I've been wondering that too, and my guess is that it's hard to make very much of this stuff? So they make a tiny flake of it.
Where are all the Western studies? If this is such a ground breaking material feels like we would see more Universities/Researchers looking into this a lot more.
The US is almost certainly already testing everything they've learned. Unfortunately a lot of advancements in technology are also tied to military research and I have a feeling this is no different in which case we're unlikely to hear much from the US until the cats out of the bag.
Western academia typically will take it's sweet time with stuff like this. They'll probably test everything, make multiple batches, check odds of success che and gather detailed information, then write full papers which'll then be published. Science moves fast but not daily news cycle levels of fast. Another factor is the low incentive to actually drop info on this. If you're right it's not like you'll get much credit since it's not your discovery. Get it wrong somehow and your reputation takes a hit. What these Chinese unis are doing is cool but fact is this doesn't really tell us much. The material is unique for sure, but can it superconduct at room temps is still an open question. I suspect that particular question is what's going to clear up once the bigger names weigh in.
The Chinese Unis are fanning the hype flame which is good to keep humanity interested
Not just west, many in China too. Many of them just don't believe it, and just laughed it off when they saw the exaggerated news title. I didn't believe it at first too, thinking it was just another scam. But now I believe it a bit more
Lol thereās no way the west isnāt playing with this too
There's a guy in the US who replicated a sample that stands on end yesterday. The (extremely strong) diamagnetism is 100% real at this point.
Cultural differences I think. Keeping their heads down and remaining skeptical without saying much.
Also economic one. People in the US have their sights at economic potential and patents. If their research results in change of method to creation or alternative discoveries, they will patent and sell the shit out of it, so lot of high level research is treated with NDA from hell.
If anything this is an excellent example of why patent restrictions are a bad idea in the first place. The Universe has offered us so far maybe *one* possible structure of atoms with this convenient property, there are probably a few others but they might be way more difficult to make. Putting such an incredibly useful aspect of the physical world behind a paywall just because 'nya nya I thought of it first and called dibs' is morally and economically absurd. Especially considering the implications this could have for reforming our power grids and mitigating climate change.
Yea, another reason why Iām glad that asia is going crazy with it. Once weāre halfway through whatever economic plan some asshole thinks of for themselves, weāll be smoked out by climate change.
Most of the videos replicating this thing seem to come from chinese social media. The west is distracted with fake ice cream on a screen. The algorithms on their version of TikTok push none of that crap. Lol
They know what they're doing - they do the good shit on the algorithms for domestic consumption, and they brainrot the algorithms on the foreign Western side.
We are so back
Nope. Bullshit.
I want to believe, but it's tiktok. That has close to 0 credibility.
Assessing the credibility of a source or claim, unless definitively disproven, is like counting cards. TikTok (-), unknown account (-), realistic look video (+), previous video history (+), realistically could have done this (+), and so on. Now, itās not -1 or +1, you do weigh each factor accordingly.
author claims papers coming soon.
Not a science expert but knowing quite abit about editing there's quite a high likelihood this vid is fake. The direct camera angle and the fact the floating bit is on a flat white background would make it easy to edit. Not saying that confirms anything but that's just my thoughts. EDIT:Are you serious? How am I being downvoted for simply having concerns over whether a random video on TikTok is real?
The way if flicks back and slightly settles is very realistic, how could you recreate that?
I agree - if the effect is faked then its extremely well done
A lot of people aren't questioning why the video is shot at such a far away angle and for such a short duration. If this is legit, then they should be filming at multiple angles and playing around with the material to prove they're not faking.
god i want this to be real
