*The Periodic Table according to Michael Jackson

Does that decay into SHeMoNa?

Edit. Corrected my bad mixed up spelling

Plutonium is not a real element.

[–] Agent641@lemmy.world 3 points 1 week ago

Plutonium can be on the periodic table but we do not grant it the rank of element.

[–] NoSpotOfGround@lemmy.world 3 points 1 week ago

It's a dwarf element.

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."

I'm confused, that's just a normal periodic table.

Found the astronomer.

[–] Swedneck@discuss.tchncs.de 1 points 1 week ago (1 children)

what? no, a normal periodic table has oxygen and carbon too!

i mean, i think most chemists are organic

few are free range though

Do you know what happens to hydrogen when the temp drops below 14K?

Yeah. Metal.

[–] Gladaed@feddit.org 1 points 1 week ago (1 children)

Metallic hydrogen may also make up parts of Jupiter's core.

[–] SasquatchBanana@lemmy.world 3 points 1 week ago (1 children)

Metallic or solid? Those are two different things, and depending on the answer, i will be going down a knowledge rabbit hole

[–] Gladaed@feddit.org 2 points 1 week ago

Metals are crystal lattices with delocalized electrons.

[–] HEXN3T@lemmy.blahaj.zone 1 points 1 week ago (2 children)

Ah yes, oxygen, my favourite metal

[–] Bishma@discuss.tchncs.de 2 points 1 week ago (2 children)

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

Can’t make fire without oxygen

Fluorine fires have entered the chat.

[–] Viking_Hippie@lemmy.dbzer0.com 2 points 1 week ago (1 children)

Fluorine fires have entered the chat.

Oh shit, someone call the fluorine fire department to save the chat!

call the fluorine fire department

Sometimes there is no such department, especially for the most vigorous fluorinating reagents like chlorine trifluoride: Sand Won't Save You This Time (Derek Lowe)

Lmao I think that particular emoji is sign language for love, not that that isn't appropriate here

[–] Bishma@discuss.tchncs.de 0 points 1 week ago (1 children)

Even apart from sign language, it's the hand sign for "hang loose" and not "throwing horns." But was as close as I could get.

[–] bestboyfriendintheworld@sh.itjust.works 1 points 1 week ago (1 children)
[–] moakley@lemmy.world 1 points 1 week ago

Pretty sure that's the emoji for "thwip".

[–] quediuspayu@lemmy.dbzer0.com 1 points 1 week ago

It sticks to a magnet, that means metal right?

[–] Balthazar@lemmy.world 0 points 1 week ago* (last edited 1 week ago) (1 children)

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 periodic table into a handful of elements plus alphas. And there's that one or 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.

What about metallic hydrogen in the core of planets?

[–] niktemadur@lemmy.world 1 points 1 week ago* (last edited 1 week ago)

"Wait, they're ALL metals?"
"Always have been."
