I highly suggest reading the entire article. That shit is pure comedy gold. Here are some highlights:

IUPAC currently recognises 118 chemical elements. The last twenty have half-lives shorter than Australian prime ministers, and are of equally limited utility to science.

Instead, we have assumed that Rex is comprised of a uniform nucleon fluid, with protons, neutrons and electrons in an idealised 1:8:1 ratio.7 This assumption will have to stand until cosmic-scale mass spectrometers can be developed.

Assuming a periodic table in which each element is represented by a 1 cm by 2.5 cm rectangle, 40 rows of 32 elements will take up one meter of space. At this scale, a periodic table incorporating element 1056 would need to be 7.82 × 1052 meters long. This is problematic, because 7.82 × 1052 meters is about 1037 lightyears, and the universe is currently estimated span a mere 93 billion lightyears. As such, the new periodic table would be a quadrillion times larger than the observable universe.

With the admin out of the way, it is now time to speculate about the chemical properties of the new element. At first, this might seem like your dentist asking you if you’re free at 3:15 on a Thursday afternoon in 2057, but the periodic table is more organised than your calendar.

Being in group 10, we might expect element 1056 to predominantly exhibit 2+ and 4+ oxidation states, and to participate in carbon-carbon cross- coupling reactions. This is unlikely however, because astronomical observations of neutron stars indicate that they do not behave like conventional atoms.

To appropriately study this exciting new branch of astrochemistry the authors have formed a new research institute the Centre for Unstable Neutron Transient Structures (CUNTS). This new institute comprises of two research groups the Baryonic Investigation Group (aka BIG CUNTS) and the Baryonic And Dark Matter Focus (aka BADMF CUNTS). We’re very proud that the exceptional nature of this research group is already being recognised with Amnesty International awarding CUNTS the 2024 Most Inappropriate and Offensive Acronym Award.While pleased to receive international recognition we have not been able to identify any offensive acronym usage and have invited Amnesty International to come and view our Award of Registered Sociopaths Equity (ARSE).

To experimentally verify this hypothesis, we proposed to send chemists to RX J1856.5−3754, but the ARC rejected our grant.

Finally, we considered the nuclear stability of our new element. Rex is radioactive in the literal sense because it emits radio waves.

We hope this paper will prompt someone to go to RX J1856.5−3754 and count its protons, so we can confirm exactly which element it is.

We thank the management of the Alien-Life Molestation Array (ALMA) for allowing us to piss around with their telescopes, while they were having lunch.

That shit almost made me piss myself from laughing.

This is problematic, because 7.82 × 10^52^ meters is about 10^37^ lightyears, and the universe is currently estimated to span a mere 93 billion lightyears.

Comedy gold. I could see Mitch Hedberg saying this.

7.81 * 1052 =8216.12 check mate atheist

J/k, you forgot this (づ ᴗ _ᴗ)づ 10^52^ = 10^52^

I just copy pasted it, so thats why its messed up.

It's the periodic table of ELEMENTS, which are defined by their number of protons.

The lone neutron deserves a place before any size neutron star.

[–] chonglibloodsport@lemmy.world 6 points 23 hours ago

Neutron stars do contain protons and electrons. It’s a misconception that they’re 100% pure neutrons.

A well-known type of neutron star is a pulsar. These rotating objects have extremely powerful magnetic fields which can only be produced by the movement of electric charges. If they were purely made of neutrons there could be no electric charges to move, and thus no magnetic fields.

The air vent is actually a particle accelerator shooting neutrons into the periodic table.

I've never seen a reverse-Saddam and I am delighted to say that I'm glad it was in this community.

It's a rare Saddam ( ^-^)ノ∠※。.:*:・'°☆

My brother had to look it up.

It's a real card. $300, he's gonna try to get one lol

Godamn a perfect PSA 10. That is a rare Saddam indeed.

Of course there is a relevant xkcd

[–] IAmNorRealTakeYourMeds@lemmy.world 24 points 1 day ago* (last edited 1 day ago) (2 children)

Do they have protons or only neutrons? because if there are no protons then it is technically just neutronium and not an element,

If they do have protons, then it is safe to assume it is a ridiculous number like 10^40. in which case I would count it as an element. And given how unlikely is for 2 neutron stars to share the number of protons, then every single neutron star is its own element,

And also, because they do not react with other atom, and if 2 collide then they merge their nucleus, we can agree that they are non reactive, and therefore we can consider them noble gasses...

Wait, are they gas?

YES, they are, if there is a single atom floating in space I think that counts as a gas

[–] wolframhydroxide@sh.itjust.works 10 points 1 day ago (1 children)

I would argue that, since they lack an electron cloud and are comprised of a collection of free-floating nuclei, they are actually a plasma.

[–] IAmNorRealTakeYourMeds@lemmy.world 4 points 1 day ago (1 children)

can we say that neuron stars are ions?

wait, are neuton stars positively charged?

[–] wolframhydroxide@sh.itjust.works 3 points 1 day ago (1 children)

Well, we can't call them atoms, which are defined by the presence of an electron cloud surrounding a nucleus.

[–] IAmNorRealTakeYourMeds@lemmy.world 3 points 1 day ago (1 children)

When will NASA finally approve my mission to send an electron cloud to a neuton star to force schools to print a periodic tables to include a neutron star.

[–] wolframhydroxide@sh.itjust.works 5 points 1 day ago* (last edited 1 day ago)

That sounds like more of an ESA/JAXA joint venture. The only stuff NASA is going to be doing for the foreseeable future is ensuring the rapid export of Space Fascism™

[–] Fleur_@aussie.zone 8 points 1 day ago

I'm sure there's at least more than 200 protons throughout regardless of majority composition

[–] ns1@feddit.uk 94 points 1 day ago (1 children)

After reading I realised that this proposal isn't a single new element for all neutron stars, but a separate new entry on the table for every individual neutron star in existence, unless there are two that happen to have the exact same number of protons which is unlikely. Sounds good to me

This is how the author is estimating it, they are assuming 1/9th of the mass is protons. No idea how good that assumption is though, there is a source which doesn't look the most convincing

[–] bleistift2@sopuli.xyz 17 points 1 day ago (3 children)

Whoopsie. I used to assume neutron stars are made of neutrons. It turns out Big Astronomy lied to me.

[–] Revan343@lemmy.ca 30 points 1 day ago

Neutron stars are made of neutrons in the same way that tapwater is made of water molecules: primarily, but not entirely

[–] Natanael@infosec.pub 5 points 1 day ago* (last edited 21 hours ago) (1 children)

Neutron stars have so high pressure that MOST but not all protons decay into neutrons plus ~~electrons~~ positrons (plus neutrinos)

Edit: (see quote below)

[–] erin@piefed.blahaj.zone 1 points 21 hours ago (1 children)

I'm not exactly well-read on particle physics, but to my understanding neutrons and neutrinos are neutrally charged and electrons are negatively charged. Why does a proton break down into net-negatively charged particles? I assume some weird quark shenanigans.

[–] Natanael@infosec.pub 1 points 21 hours ago (1 children)

https://abc.lbl.gov/wallchart/chapters/03/2.html

I got stuff mixed

In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e - +. In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n. Both reactions occur because in different regions of the Chart of the Nuclides, one or the other will move the product closer to the region of stability. These particular reactions take place because conservation laws are obeyed. Electric charge conservation requires that if an electrically neutral neutron becomes a positively charged proton, an electrically negative particle (in this case, an electron) must also be produced. Similarly, conservation of lepton number requires that if a neutron (lepton number = 0) decays into a proton (lepton number = 0) and an electron (lepton number = 1), a particle with a lepton number of -1 (in this case an antineutrino) must also be produced. The leptons emitted in beta decay did not exist in the nucleus before the decay–they are created at the instant of the decay.

Thanks for the clarification! That all makes sense to me.

No, seriously, stuff like electron metal and strange matter.

[–] Kolanaki@pawb.social 42 points 1 day ago* (last edited 1 day ago) (3 children)

Are they elements? 🤨

Personally, I think it's high time we went back to just 4 of 'em. Earth, Wind, Water, Fire. It's so much easier to remember them all.

[–] wewbull@feddit.uk 3 points 1 day ago (2 children)

Earth, Wind and Fire is where it's at.

[–] apotheotic@beehaw.org 2 points 1 day ago

This collapse generates a body of neutron-removed matter with a radius as small as 10 km, but a mass comparable to our Sun’s. As such, they are the densest known material outside of Twitter, at around 1017 kg/m3. For American readers unfamiliar with SI units, that means a pair of truck-nuts made of neutron star would weigh as much as ten million aircraft carriers.
