How come no one mentioned it yet?

Guys, check out this short film :)

This is amazing :)

It’s what should have been expected though. Lots of people check it out during the hype, and later only those who actually found it useful/interesting/fun remain.

Most of the hype-launched services should have similar numbers.

Likely? I feel like I’ve read several news stories confirming arms shipments from China here and there. Weren’t there?

Oh right, didn’t consider some may remain sealed, that’s cool.

Out of weird drinks, I’m betting on kykeon, an LSD-like psychedelic drink made from ergot-infected barley :)

Considering that it sank like 2000 years ago, would there be any detectable molecular traces left to figure out amphoras’ contents? Or would everything be destroyed by now?

I had a CT scan after an accident, and no one told me what contrast is going to feel like, the nurse simply injected me without any explanation.

And omfg, that might’ve been one of the scariest 30 seconds of my life. It felt like I was injected with straight up lava. My whole body was burning from the inside, and I felt like I would just spontaneously combust any second. It very quickly subsided though and there was no negative reaction overall, just higher sensitivity than average. But holy shit, I would want to know about stuff like this beforehand.

You know scientists always trying to make things happen but never asking if they “Should”?

I’ve never seen someone use this as an argument, only as a joke. Can you provide some examples of the things that you think scientists tried to make happen without thinking whether they should or not?

Also, how is user-specific trust at play here? I never even look at usernames, instead I will upvote or ignore posts based on their content. I don’t think you can really ease Lemmy/kbin users into believing some divisive nonsense that easily.

Mostly because august hasn’t started yet.

With stuff like “act of god” clauses and limited liability bankruptcies it might not really bother them that much.

“I’ve been very interested in things like universal basic income and what’s going to happen to global wealth redistribution,” Sam Altman, Worldcoin’s cofounder

Holy crap it’s Sam Altman, the CEO of OpenAI. After that recent article about his $2 Kenyan workers it’s much harder to believe in benevolent intentions.

You’re right, haven’t heard about that one. They actually do use superconducting magnets on a train that runs along a magnetic track.

But I feel like my feasibility comment still stands. It seems like all they had built is a 18km test track, and there’s some info about extending it to 48 km, but it doesn’t seem like the extended part uses superconducting tech yet, it only mentions regular maglev. The Tokyo — Osaka line is planned for 2037. So yeah, its technically possible, but it’s not like you can cover Europe or the US with this type of track for any sensible amount of money.

That’s the cool part about room temperature superconductors, they make this type of tech possible on much larger scales.

Not surprising really. Google has decided that it really doesn’t want me to use it so I switched to DDG a couple of years ago. And it doesn’t feel like I’ve lost anything of value.

You still need a magnet-superconductor pair for quantum locking and magnetic levitation. This is called the Meissner effect and it seems like it has been confirmed for this material. Here’s a video showing an example of such a system.

Before, the best way to scale this up might’ve been to make permanent magnet rails and run a superconductor train along those rails, but that would have been totally infeasible and inapplicable in real life, since building rails out of permanent magnets is expensive and dangerous, and the train would need to house a really large superconductor chilled to liquid nitrogen temperatures. You couldn’t have built a track out of superconductors irl because good luck keeping those at the temperatures required for superconductivity to kick in.

If this material turns out to actually work as claimed and to be producible at scale, you can switch those and make an electromagnetic train that travels along superconductor tracks. Which is way easier, cheaper and much more doable in general.

But the earth’s magnetic field is extremely weak, and even the tiniest pieces of superconductors are unable to lock with it. So no, it does not allow for trackless levitation.

But a cool new train system design becomes possible though!

He’s playing with his new middle age crisis toy. Cars and spaceships got boring.

Not really. If that turns out to be true (nothing is guaranteed yet), the processes described are pretty straightforward and don’t require any super-advanced tech to be reproduced. Full-scale production could be rolled out in mere years. That would become beneficial for stuff like MRIs or electric cars as soon as production starts.

After that, my guess would be that some large-scale energy infrastructure projects, for example, could be completed in about a decade.

Locking social norms at some predetermined stage is a great way to curb all progress. Like, slavery was a social norm at some point.

Long-distance energy transfer without energy loss will make it possible to connect more energy grids and sources together, so stuff like the saharan desert providing solar power to Europe, for example, suddenly becomes feasible. Maglev trains will no longer require lots of power to run, since they could utilize superconductor magnetic levitation. You could make super-efficient processors that wouldn’t really heat up at all. Superconductors are also key to quantum computers, so expect lots of advancements in that field as well. They will also make it much easier to build and run fusion power experiments.

Lots of tech in general would benefit from this discovery, stuff like MRIs, electric vehicles, space telescopes or particle accelerators would become way more efficient, cheaper and easier to produce.

Edit: also, check out this video by Isaac Arthur for some more sci-fi examples of what this tech can be used for in the future (discussed in the second half). It’s more space-colonization-focused and kinda like a thought experiment, but interesting nonetheless.

Reposting my comment from another thread to add a bit of context in case anyone’s curious.

So I read the paper, and here’s a tldr about how their material apparently gains its properties.

It is hypothesized that superconductivity properties emerge from very specific strains induced in the material. Hence why most of the discovered superconductors require either to be cooled down to very low temperatures, or to be under high pressures. Both shrink the material.

What this paper claims is that they have achieved a similar effect chemically by replacing some lead ions with copper ions, which are a bit smaller (87 pm for Cu vs 133 pm for Pb). This shrinks the material by 0.48%, and that added strain induces superconductivity. This is why it apparently works at room temperature — you no longer need high pressures or extreme cold to create the needed deformation.

Can’t really comment on how actually feasible or long-lasting this effect is, but it looks surprisingly promising. At least as a starting point for future experiments. Can’t wait for other labs’ reproduction attempts. If it turns out to be true, this is an extremely important and world-changing discovery.

Fingers crossed :)

Oh I bet there are several labs that are already on it :)
