Can’t make fire without oxygen. That’s pretty metal 🤟

Matrix missed a great chance at an awesome unrealistic underwater flight scene.

It sticks to a magnet, that means metal right?
pHr34kY@lemmy.world 10 months ago
Do you know what happens to hydrogen when close to 0K?
Yeah. Metal.
Gladaed@feddit.org 10 months ago
Metallic hydrogen may also make up parts of Jupiter’s core.
SasquatchBanana@lemmy.world 10 months ago
Metallic or solid? Those are two different things, and depending on the answer, i will be going down a knowledge rabbit hole
Shou@lemmy.world 10 months ago
That’s fucking badass
threelonmusketeers@sh.itjust.works 10 months ago
Doesn’t it also need to be under immense pressure? I don’t think low temperature alone is enough.
pHr34kY@lemmy.world 10 months ago
Yeah, I think that may be the case.

I’m confused, that’s just a periodic table.
threelonmusketeers@sh.itjust.works 10 months ago
Found the astronomer.
Swedneck@discuss.tchncs.de 10 months ago
what? no, a normal periodic table has oxygen and carbon too!
Balthazar@lemmy.world 10 months ago
Physicists are notorious for approximating, and astronomers are even worse. But there are some subfields where they care about being more precise, and you maybe break the product table into a handful of elements plus alphas. And there’s that one out two people getting exquisite spectral resolution and signal-to-noise on a few stars and measuring the abundance of Technetium or whatever.

It’s why I fucking love astrophysics. There’s so much handwaving because so much information is observed.
But without the handwaving you can’t find crazy ass things like nuclear fusion being behind the power of stars. You find these really big numbers everywhere that make the “normal stuff” negligible.
It not that the precision isn’t important, it’s just not always relevant at particular scales, like the scale of space.

Plutonium is not a real element.
NoSpotOfGround@lemmy.world 10 months ago
It’s a dwarf element.
Agent641@lemmy.world 10 months ago
Plutonium can be on the periodic table but we do not grant it the rank of element.

What about metallic hydrogen in the core of planets?

“So, they’re ALL metals?”
“Always have been.”threelonmusketeers@sh.itjust.works 10 months ago
Funnily enough, probably not a metal according to astronomers.

Iodine is a transition metal I will die on this hill.
threelonmusketeers@sh.itjust.works 10 months ago
Care to defend your position? Iodine is certainly not in the d-block…
ornery_chemist@mander.xyz 10 months ago
The intended joke is that hypervalent iodine compounds like Dess-Martin periodinane different oxidation states like you often see for transition metals. As an example, the mechanism usually drawn for oxidations by DMP is similar to those drawn for, e.g., PCC/Jones reagent, where the electrons removed from the substrate is “banked” at the metal center. Obviously, redox chemistry is not at all limited to transition metals, but I am often surprised at iodine’s propensity to engage in it. A lot of research over the past decade or two has also developed redox catalysis with these reagents, reactivity which is commonly (though again not always) the purview of transition metals.

And if you ask a cosmologist what the universe is made of, they go “Well, there’s a lot of dark matter, and even more dark energy. And then there’s a tiny bit of some matter or something idk lol.”
KairuByte@lemmy.dbzer0.com 10 months ago
Read that as cosmetologist and was thoroughly confused.

Should also have iron on there too

That’s because these two account for something like 99% of all normal matter in the universe
