Touché, but will you eat your hat if it turns out to be true?
Yup!
No condiments and I get to pick the hat. Live.

Successful room temperature ambient-pressure magnetic levitation of LK-99

Re: Successful room temperature ambient-pressure magnetic levitation of LK-99
#702I love how the nytimes front page is just all Trump and political crap. Literally not a word about this, and if it's real, its like the biggest thing ever.
NYT actually is the only newspaper outside of Korea to get into contact with the authors, and received an exclusive video from the professor. Go to their science section. Now it isn't top news, but when it is confirmed, it'll be front page news on every western newspaper.
This furthers my point. They even got an exclusive and still run Trump stuff.

#703For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound. For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-) Other things that could happen: 1)…
1. Cure for aging 2. AGI exists and ends up being somehow, unexpectedly easy to control 3. Russia / China / North Korea eventually become democratic Some of the “good” black swans at the top of my mind…
That third point is so odd and shoehorned in. If you're talking about AGI and immortality, why not dream a little bigger? How about achieving actual democracy anywhere in the world? Not just in state elections, but economic democracy broadly speaking. Right now we are just going on pretending, and this western chauvinism of yours is a little embarrassing.

Passports were originally a temporary wartime measure. Not exactly something to celebrate
I don't understand why passports would be a good swan invention. Are we happy about having less freedom? I can't just cross USA to Mexico, I need to be identifiable. Governments could screw me up if they wanted to and the passport is only helping them.

#705I no nothing about superconductors. And have been largely ignoring this until it seemed more certain.
Can someone ELI5 why this matters? What does it enable technologically?
Flying cars? Fusion reactors? Magic fix for global warming?
Re: Successful room temperature ambient-pressure magnetic levitation of LK-99
#706I get the idea of superconductivity at room temperature in theory. But I don't have enough knowledge to understand in real terms, how will the world change if this is true?
Railguns. Everywhere.
I'm thinking coil guns instead. Room temperature superconductors don't solve the rail erosion issue with railguns, but I think should greatly increase the performance of coil guns.
My thinking is that zero resistance through the projectile itself and through the rails would help, but you still need to make an electrical connection between the projectile and the rails. Either this is done with a plasma arc or physical contact, but either of these causes erosion of the rails even if there is no electrical resistance through the rails or projectiles. Am I missing something?

Unpopular opinion of mine: I think that viable fusion energy would be the final nudge to our demise. Our civilisation is an energy-junkie who happened to stumble on a huge bag full of cash around 1860 and the discovery of oil distillation. Since then, we have been on a hallucinating trip, burning down our house in the process. Viable fusion is essentially another huge pile of cash being deposited right across the str…
how exactly is oil distillation or its results "burning down our house" and how is that applicable to fusion tech?

So do you think it's the use of energy in and of itself that causes issues?

No resistance in wires means limitless power lines, phone lines, batteries charge instantly..
