Today I Learned

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] 15 points 6 days 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] 20 points 6 days ago (2 children)

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

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 5 days ago (1 children)

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

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

My Lord, the commoners mustn’t see you so

[–] [email protected] 11 points 6 days ago

Ridiculous! Tariffs on antimatter now!

[–] [email protected] 7 points 6 days ago (1 children)

I bet it gets you way high

[–] [email protected] 5 points 6 days ago

From the velocity imparted by the explosion, yes

[–] [email protected] 8 points 6 days ago

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

[–] [email protected] 6 points 6 days ago

I should think about selling some of mine.

[–] [email protected] 5 points 6 days 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] 9 points 6 days 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

[–] [email protected] 2 points 6 days ago

That's fucking cooooool

[–] [email protected] 7 points 6 days ago (1 children)

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 6 days ago

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

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] 5 points 6 days ago

a handful of atoms would be a lot of atoms!

[–] [email protected] 2 points 6 days ago
[–] [email protected] 110 points 1 week ago (1 children)

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

Shouldn’t it cost -$60 trillion?

Nearly as expensive as printer ink.

"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."

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

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

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

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