Notice how the rock does the same thing irrespective of which way the magnet is oriented? Notice the absolute lack of refrigeration equipment? This is the real deal. I feel like we can finally relax. Everything's going to be just fine.

You cute twinks keep posting about this and no one has deigned to explain what it is
Or maybe someone has but they buried it in 394993301 nerd cute twink words of exposition or whatever
Tell me what this is in normal person terms right now or I'm banning anyone who posts an LK99 thread or whatever
No I don't want to hear that it's a magical superconductor that doesn't generate heat or whatever
Google said something about levitation
Does it levitate
Is this witchcraft
Why won't everyone shut up about this
Explain NOW. It is your job to educate me.

We need less energy to power our electronics and we need less complicated heat management systems to keep devices from blowing up. The novel material they're using is a composite of very simple and available things.
The released preprint does not give exact instructions, and a final draft will eventually be released, but the implications of this discovery could increase global GDP by tens of trillions of dollars by the end of the decade. So many labs are motivated to crack the preprint and replicate the experiment, with more established labs being slower to do so because of the reputational risk of calling this wrong.
I don't know if I believe it yet, but if it is replicated by a non-foreign lab, I'm quitting my job on the spot and pivoting into tech.
the magneticism/levitation is just visual proof that the superconductor is working but is super unimportant for what it does, which is send energy from the source to circuits.

My professor said if any of us proved P=NP, created a room temperature superconductor, or became a wealthy tech morgul and donated lots of money to the university-- then they would get the funding to build a new "state of the art" computer science, math & physics building, instead of us having to use the shittiest, draftiest, building on campus full of rats. Then he said they would probably name the new building after us and posthumously add a statue of us in the front.
He was daydreaming real hard about not hearing the ceiling tile rats anymore lmao

Electricity makes things hot because it can't pass through things perfectly
It can pass through this perfectly. That's a property that's usually only possible at mega fat pressures or mega cold pressures (it's why MRIs are cooled with helium)

Depends how cheap it is to make. From what I've gathered this is reasonably cheap in terms of raw materials/ processing which is why random people are making it instead of BlackRock particle hormone accelerators or whatever
If it's not prohibitively expensive there's no way they'd pass up on the absolute performance goldmine it represents. It'll probably be a while before the manufacturing methods catch up to silicon tho.
Frankly if it's viable to mass produce as a raw material it'll be made by the boatload

Phone games always seem weird but having to charge less would be pretty cool I guess

A big enough neodymium magnet does have a perceptible effect even without the 14 Tesla field.
besides that you are betting on the purity of the metals. The lead or copper may have had some ferromagnetic materials in it

when you use electronics they are not perfectly efficient so lose current and electricity that you feel as heat. this breakthrough apparently solves that efficiency loss problem through some material science (no i dont know how)
imagine now your brand new cpu didnt need a cooler bc it didnt get hot. it doesnt waste as much electricity. it performs better without increasing input. what if your car's MPG shot up by 5x overnight?
now think bigger: super computers powering ai, car batteries lasting longer, or server clusters hosting shitty cat forums reducing the need for paypigs
this is all after a cursory glance at some article i barely read so it could all be wrong but im not the one posting these threads so im not a complete straggot

It still costs (a tiny amount of) energy to flip bits, but 99.999% of the power cost of a computer is because of energy lost to heat. Instead of needing 500W to run a GPU, it would theoretically take <1W. In a modern information-heavy industry, a lot of the operating costs of a big company will be in compute and a big chunk of that is the power cost of running a large server farm, plus the power cost of cooling that server farm. If the computers are made of superconductive material, the global savings amount to billions of dollars annually.

Watch this video first (at least the cool levitation part)
The reason that works and the thing levitates is because it was cooled to a low temperature like -200ยฐF. When that material gets that cold, quantum magic happens and it floats in a magnetic field. This is that same thing but without needing to be super cold
