This summer, a South Korean lab declared a world-changing breakthrough. Their claims didn’t survive scrutiny, but physicists hold out hope for the holy grail of electric efficiency

“possible real solution to the energy crisis” that “could change everything”. That’s how recent headlines billed the mundane lumps of a dirty-looking material known as LK-99 reported by scientists in South Korea in July. Their findings were described in two papers (https://arxiv.org/abs/2307.12008 and https://arxiv.org/abs/2307.12037) posted to the arXiv preprint server – a website where researchers present work that has not yet been subjected to peer review. They said they had “for the first time in the world” made a superconductor that worked at room temperature and at everyday pressure.
A superconductor is a material that can conduct an electric current without any resistance, meaning that no energy is lost through heat. Superconductors have been known about for more than 100 years, but previous ones have worked only at extremely low temperatures or when under very high pressures. LK-99 on the other hand, the South Korean team said, was superconductive just sitting there on a benchtop. If they had been right, the discovery would genuinely have merited the word “revolutionary”.
But after weeks of feverish speculation and frantic attempts worldwide to make and test the new material, many experts in the normally recondite field of solid-state physics now think the claims were almost certainly wrong. There was reason to be sceptical from the outset: the South Korean scientists, Sukbae Lee and Ji-Hoon Kim of the Seoul-based startup company Quantum Energy Research Center had no track record in the field, and LK-99 – named after them and the year they began studying it – didn’t look much like high-temperature superconductors seen in the past.
A broad consensus is now emerging that the apparent signatures of superconductivity the Korean team reported – zero-resistance and a magnetic phenomenon called the Meissner effect – may have more mundane explanations. But even if LK-99 is a blind alley, the quest for a wonder material that is superconductive under everyday conditions will continue.
“It will happen,” says the physicist Jorge Hirsch of the University of California San Diego, “although it is hard to tell when.” But when it does, he says, it will result in “all sorts of incredible applications we haven’t even imagined yet”.
============
so when years ago. something was happened in south korea.
this level of shit.
some fucking fascinating space rocket was launched suddenly.
and no one know.
and after that.
south korea goverment trying to explain it.
"omg we check about situation... it was actually secret test of solid fuel rocket!!"
and they revealed this.
look at this.
do you believe this shit????
this. seems looks like can't even flying few of killometers.
looks like garbages.
south korea don't have any tech. and nothing but bullshit nation.
but because NAZI HQ is moving.
there is superconductivity rumor was there.
and i know clearly
i know south korea have no ability to do that.
because. we are kimchi nation.
we eat rotten cabbage
i know south korean can't make any space rocket or superconductivity shit.
but it is about NAZI HQ is moving and japanese migrant plan.
so it is easy to know truth.
whatever thing is.
adding this "japan behind of this".
so south korea elected in chief of UN human rights council , and japan behind of this.
category 4 hurricane milton that artificial made up weather weapons attack on american civilan and property by treason crime regime and compromised military , and japan behind of this.
like this.
adding it. then can explain every truth.
whatever shit + japan behind of this.
"Internet Archive hacked, data breach impacts 31 million users" and japan behind of this.
"Afghan national charged with election day terrorist plot in US" and japan behind of this.
"Russia blocks instant messaging platform Discord" and japan behind of this.
"MI5 warns 75% of terror threats are of Islamist origin" and japan behind of this.
"Global Crackdown: How foreign censorship threatens American free speech" and japan behind of this.
whatever bad thing whatever villain and japan behind of this.
speak this.
