What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Given the technology to create and store antimatter in quantities exceeding a handful of atoms doesn't exist, it's a bit ridiculous to extrapolate a price per gram for it.

Atoms are made-up by Big Small so they can sell you more less!

Shouldn’t it cost -$60 trillion?

Does it even have mass like that?

[–] [email protected] 5 points 1 week ago

a handful of atoms would be a lot of atoms!

Nearly as expensive as printer ink.

Starts printing Anti-Authorities

[–] [email protected] 18 points 1 week ago

Anti-Authorities save lives instead of take them.

[–] [email protected] 11 points 1 week ago

Stop posting my wish fulfillment, it's distracting. 😂

[–] [email protected] 7 points 1 week ago

nah, they'll just let you print antimatter ink on matter paper, and then claim that the explosion was your fault for counterfeiting

[–] [email protected] 81 points 1 week ago (2 children)

Idiots, just fill a jar with matter and flip it over.

This is why it's so dangerous to go to Australia.

Planes have to stop at the equator so everyone can get their matter jars ready to switch before they convert naturally

Genius, where can i invest in your company!?

That’s not even buying it; you’re renting it by the nanosecond.

It's a subscription model for the artificial stuff. The natural version is dirt cheap. It's always the middle man with these modern services, I tell you.

Why do people post things like this? And who cares? It doesn't matter; it antimatters.

[–] stembolts 15 points 1 week ago

This is just an irresponsible post.

Be careful putting matter and antimatter so close in a sentence.

You'll kill us all.

The reason why it's called antimatter is because the polarity of the nucleus and electrons are reversed. There are also antineutrons that have a neutral charge. It all still has mass, but will obliterate upon contact with regular matter

[–] [email protected] 12 points 1 week ago

There are also anti neutrons that have a neutral charge

Expanding onto this, it raises the question: how is a neutron different to an anti-neutron?

A neutron can be though of a particle composed of 2 down and 1 up quarks and lot of gluon's that keep everything together. The gluon is its own antiparticle, so the antineutron has 2 anti-down quarks, 1 anti-up quarks and gluons. This way it becomes a different particle despite also being of neutral charge.

[–] [email protected] 31 points 1 week ago
[–] [email protected] 5 points 1 week ago

yes, its the same as normal, its just the "Spin of the particles that are opposite", if you get down deeper, the quarks are opposite.

1 gram of antimatter stored? Forget the explosion—imagine the insurance premium on that thing.

I thought it was HP inkjet printer cartridges? I think that's around $60 trillion per gram, isn't it?

[–] [email protected] 16 points 1 week ago

Just wait until we start having it manufactured in a cheap labor market. The prices will plummet! It'll likely be mostly fake, but that's the price we pay for cheap antimatter.

[–] [email protected] 15 points 1 week ago* (last edited 1 week ago) (2 children)

That's so stupid: You can make antimatter at home for tree fiddy. Just buy a bunch of bananas and wait for the potassium to decay into positrons. EZ

I didn't even know we could get a gram of anti-matter, cause don't they make it proton by proton, and they also don't exist for that long?

Ridiculous! Tariffs on antimatter now!

[–] [email protected] 11 points 1 week ago* (last edited 1 week ago) (1 children)

With a gram of antimatter, you can probably blow a city-sized crater into Earth, so yes, 60 trillion seems like a fair price.

Edit: oh, it's only 21 kilotons. The stuff is overpriced. :)

[–] [email protected] 8 points 1 week ago (1 children)

I could snort 5 grams in one weekend, so yeah, overpriced.

[–] [email protected] 5 points 1 week ago

My Lord, the commoners mustn’t see you so

[–] [email protected] 8 points 1 week ago* (last edited 1 week ago) (3 children)

I thought element 118 was like $60 quadrillion a gram because they only manged to make like 3 atoms of it.

Edit:

  • 2.05x10^21 atoms in a gram of element 118
  • 5 atoms synthesized so far

Assuming they somehow managed to spend only $1 making every atom, that's $2,050,000,000,000,000,000,000 per gram.

no you wont trick me. its printer ink...

I bet it gets you way high

From the velocity imparted by the explosion, yes

I should think about selling some of mine.

[–] [email protected] 5 points 1 week ago (2 children)

Can we even contain it? Afaik, it's destroyed basically the instant it is created because there's regular matter everywhere.

[–] [email protected] 10 points 1 week ago (1 children)

Fun fact; the standard model actually allows for spontaneous particle-antiparticle pair generation, so long as the pair mutually annihilate within some hbar defined time limit and conservation laws aren't broken at a macro scale. This is the mechanism behind hawking radiation too; some of the energy given off by black holes is caused by spontaneous pair generation that happens such that one of the pair is created beyond the event horizon and the other member is created before the event horizon, causing one to be trapped and the other to be jettisoned into space.

I know that doesn't really relate to your comment about containing antimatter but I counter with the following: I'm profoundly autistic and the standard model has been a special interest of mine before. I couldn't resist the chance to infodump a bit

It can be contained using magnetic fields, that has been possible since 2010: https://newscenter.lbl.gov/2010/11/17/antimatter-atoms/

Scientists are even preparing to transport it in the near future: https://glassalmanac.com/why-scientists-are-transporting-antimatter-in-a-van-uncover-the-reasons/

[–] [email protected] 5 points 1 week ago

That's the opening scene of an X-Files episode for sure.

[–] [email protected] 5 points 1 week ago (2 children)

Ah, that's why we haven't used it in weapons yet.

I figured because any amount of usedul antimatter annihilateing causes gamma rays that cook the planet, but $60T makes it a bit more prohibitive

[–] [email protected] 6 points 1 week ago

Yeah, I usually only buy a couple of grams at a time.
