>At supercold temperatures, hydrogen molecules first condense into a liquid, then a solid with the molecules intact. When squeezed together, the molecules stack up into a solid form. More than 80 years ago, the physicists Eugene Wigner and Hillard Bell Huntington predicted that hydrogen, under high enough pressures, would turn metallic, with the hydrogen molecules broken apart and the electrons squeezed loose.

>Scientists have momentarily transformed hydrogen into a liquid metallic state with violent shock wave experiments. Planetary scientists are convinced metallic must exist inside Jupiter, to generate that planet’s powerful magnetic fields.

>But so far, no one has convincingly demonstrated the solid metallic hydrogen state predicted by Wigner and Huntington. In the Harvard experiment, a small amount of hydrogen was placed between two diamond tips about one 850th of an inch in diameter and cooled to -433 degrees Fahrenheit. Initially transparent, the hydrogen became dark as it was squeezed. Then, at nearly 72 million pounds per square inch, the hydrogen became shiny, reflecting 90 percent of light shining on it, the scientists reported.

How is that possible? Sounds like a bullshit number to me.

No, that's Dragonforce.

>>If some theoretical predictions turn out to be true, the new state of hydrogen could even be a solid metal that is metastable — remaining solid even after the crushing pressure is removed — and a superconductor, able to conduct electricity without resistance, Dr. Silvera said.
Wouldn't it be able to be found in nature then? As a byproduct from a supernova.

What are some potential applications of metallic hydrogen?

>>58670718
Maybe used as a rocket fuel together with LOX. You wouldn't have to pressurize it, so you'd save weight.

How many supernovas do you know of, of which we inspected the byproducts of closely enough?

>>58670748

Too expensive for car fuel?

>>58670771
Well most of the matter in the Solar system is the byproduct of a supernova.

Small area of contact with a large force acting on a large area on the outside

>>58670705
It seems to require liquid hydrogen to be achieved, which would be on the other end from a supernova.

Sorry, you seem to be posting in /g/ - Consumer Electronics.
Please take your technology-related posts elsewhere.

>>58670843
You dont need to lower the temperature of something to put it into a liquid state.

Just look at co2 on the surface of venus.

I believe lowering the temperature of hydrogen atoms causes them to contract and makes it much easier to apply pressure from the diamonds. However in a place like jupiter im sure the pressure far exceeds 72m ppi

>>58670690
>sounds like bs
>but i don't know

this is how trump and alt facts work

So basically we just need to dip a large magnet into Jupiter to get superconducting liquid hydrogen, and then fast hardware?

>>58670690
100 ton press (from harbor freight) with a .005" contact area is 40mil PSI

>>58670790
Most of the matter in the universe is hydrogen

>what is pascals law?

>>58670889
Lowering the temperature of the hydrogen doesn't make them contract, it just reduces the amount of energy that each molecule has, which makes them more readily condense to a solid

do they finally answered the age old question, eh?

>>58670963
yes.

Most matter outside the sun in the solar system is a by-product of a super-nova

Most matter in the universe is hydrogen

>>58670748
What does pressure have to do with saving weight?

The rocket fuel application has to do with the fact that burning the stuff solid would be safer and release a lot more energy.

>>58671009
Not quite, in the birth of the universe itself is what created the hydrogen you see before you, when it was born the universe was 90% plus hydrogen

Supernovas made the heavier stuff tho

>>58671029
LH2 pressurized tanks are heavy m8

https://www.google.com/amp/www.universetoday.com/47966/jupiters-core/amp/

so they think around 200 GPa is where this stuff happens at, I dont really really like converting that to ppi

>>58670900
Turns out the 72 million psi was in fact , only 700 psi. ;^)

>>58671029
Pressurizing something means pumping in atoms which adds overall mass.

>>58670705
It's been theorised that Jupiters core could be made out of metallic hydrogen

I want to know how much 200 GPa is in pixels per inch.


>It's about 29m psi, btw

>>58672435
29 metre pixel second integer?

>>58669918
Lowering of standards to pander to retards who don't know shit through big-name association is a pretty common theme in modern science unfortunately. It's the same in my field. The fact silvera says
>“If we did it again, we’d get the same result, I’m certain,”
Is pretty fucking scary, too, in multiple ways.
Only time will tell I suppose.

>>58670024
Remember, they may actually even be the hardest metal of all time. We just don't know yet.

In the classical view. In the modern view, the matter in the universe is made up mostly of dark matter. Unfortunately we don't know much more about it than the measurable gravitational effect it has on baryonic matter.

To be fair, it's one of the most iconic memes of older 4chan, the fact you don't even recognize it, even if you weren't around for it's prime, means you're particularly new.

>What does pressure have to do with saving weight?
It takes heavy equipment (tanks) to keep it under pressure. Metallic hydrogen could shaped however and just stored as rods or something.
