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.

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

[–] [email protected] 14 points 1 day ago

This is just an irresponsible post.

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

You'll kill us all.

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

[–] [email protected] 180 points 2 days ago (5 children)

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.

[–] [email protected] 107 points 2 days ago (1 children)

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

Shouldn’t it cost -$60 trillion?

[–] [email protected] 21 points 2 days ago

New infinite money glitch unlocked!

[–] [email protected] 5 points 2 days ago

a handful of atoms would be a lot of atoms!

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 day ago (1 children)

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

[–] ILikeBoobies 5 points 1 day ago

My Lord, the commoners mustn’t see you so

[–] [email protected] 97 points 2 days ago (1 children)

Nearly as expensive as printer ink.

[–] [email protected] 49 points 2 days ago (2 children)

"Your printer has detected 3rd party antimatter. Please only refill with Genuine HP(tm) AntiMatter cartridges. Authorities have been notified and are enroute to your residence."

[–] [email protected] 31 points 2 days ago (2 children)

Starts printing Anti-Authorities

[–] [email protected] 18 points 2 days ago

Anti-Authorities save lives instead of take them.

[–] [email protected] 11 points 2 days ago

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

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

[–] [email protected] 51 points 2 days ago (1 children)

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

[–] [email protected] 10 points 2 days ago (1 children)

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

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.

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

I bet it gets you way high

From the velocity imparted by the explosion, yes

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 2 days 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 2 days ago
[–] [email protected] 5 points 2 days 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.

I should think about selling some of mine.

[–] [email protected] 11 points 2 days ago

Ridiculous! Tariffs on antimatter now!

[–] [email protected] 16 points 2 days 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 2 days ago* (last edited 2 days 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

[–] [email protected] 2 points 1 day ago

This leads to a modified version of the uncertainty principle: either you have a banana and can know the size of something or you have positrons and are unable to measure size.

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

[–] [email protected] 13 points 2 days ago (1 children)

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?
