Everyone has a plan until they get hit by a rock.

[–] Kolanaki@pawb.social 17 points 1 week ago (3 children)

Everyone wants to be tall, but they forget that Goliath went down after being hit with a pebble.

[–] Viking_Hippie@lemmy.dbzer0.com 12 points 1 week ago (2 children)

With apologies for the pedantry, the sling stone was more likely "from the size of a billiard ball to a tennis ball.” and capable of “slightly less stopping power than a .44 magnum cartridge.”

So yeah, being tall doesn't stop you from going down from the equivalent of being shot in the head..

[–] Rozz@lemmy.sdf.org 7 points 1 week ago

Exactly. Sling yes, pebble no

[–] Kolanaki@pawb.social 5 points 1 week ago (1 children)

To a giant, that's a pebble. 😌

[–] Saleh@feddit.org 8 points 1 week ago* (last edited 1 week ago) (1 children)

most pistol bullets are pebble sized for humans

Most pistol bullets are shot from pistols, not slings.

[–] echodot@feddit.uk 8 points 1 week ago (3 children)

So you're telling me that dwarfs are immune to a thrown brick?

[–] teegus@sh.itjust.works 4 points 1 week ago (1 children)

lower centre of gravity, less chance of toppling over

[–] Saleh@feddit.org 3 points 1 week ago

You want to fall over. The more energy goes into moving you, the less energy goes into destroying you.

[–] MotoAsh@lemmy.world 2 points 1 week ago

I mean... more than Goliath.

If you try to throw a brick at Bridget Powers, she'll fucking stab you!

[–] TachyonTele@piefed.social 4 points 1 week ago

I like that

[–] RaivoKulli@sopuli.xyz 2 points 1 week ago (1 children)

What if your plan includes getting hit with a rock

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

Then their plan is complete

[–] RaivoKulli@sopuli.xyz 1 points 1 week ago (1 children)

No but it just includes it, as part of it, not as the ultimate part

[–] TachyonTele@piefed.social 1 points 1 week ago

They better have some paper with them, or they're beat.

[–] Tylerdurdon@lemmy.world 33 points 1 week ago (1 children)

Hell, a big enough chunk of any material from the periodic table will do a person in if it's thrown hard enough.

[–] Viking_Hippie@lemmy.dbzer0.com 13 points 1 week ago (2 children)

Idunno, a lot of those chunks would be too cold to throw in solid form..

watches as some of the world's foremost engineers and chemists collaborate on a billion dollar project to build a machine that creates solid helium and then chucks it at random passersby

[–] leftzero@lemmynsfw.com 3 points 1 week ago

Throw 'em fast enough, they won't have time to melt. 🤷‍♂️

[–] Gustephan@lemmy.world 2 points 1 week ago (1 children)

Napkin math plan: a really big fucking laser. Use aforementioned big fucking laser to generate optical vortices; with the specific intent of creating a brief localized vaccuum state along the desired trajectory. This will require R&D during building. Concept is similar to how lightning works; "ionize" (or in this case, vaccumize?) a path, then send the payload. From there add in whatever condenser you need to generate solid forms of the substance you want to chuck and some kind of mag lev style launch rails to accelerate it into the vaccuum path. Theoretically if you can create an effective enough vaccuum along the trajectory, you shouldn't have to worry about the payload being affected by drag heating in transit.

Possible? Probably not. Would the government give general atomics a few billion to try anyway? Probably

[–] anomnom@sh.itjust.works 1 points 1 week ago (1 children)

Aren’t they already using lasers to cool down the hydrogen? Or maybe I’m just thinking of atomic cooling for absolute zero experiments.

[–] Gustephan@lemmy.world 1 points 1 week ago

Yep! To both I think? I remember back in like 2021 there was a paper where some team used lasers to induce radiation pressure in a beam of hydrogen and got it to cool down significantly, but I don't remember if they reached or were shooting for absolute 0. My napkin plan was thinking more along the lines of "optical vortex --> optical tweezers --> OAM molecules in the trajectory out of the way" rather than cooling them down. I'm pretty sure optical tweezers have only been achieved in close range lab conditions manipulating a very small number of particles, so the idea of doing it on enough particles to create a flight path and also at the distance you'd want to fire a projectile is probably unhinged

Achtually, most Uranium is uranium-238, which is mostly stable. People use it in glass and decorations and it causes them to glow in blacklight. It's safe as long as you aren't in daily constant contact with it or eat it.

Uranium-235 is less stable, but makes up less than 1% of Uranium on Earth. The quantity in natural uranium isn't much riskier unless you're exposed to enriched uranium which has more Uranium-235.

The byproducts of a chain reaction of U-235 fission are what cause most of the dangerous radiation. Which is to say, the leftovers of a nuclear explosion are very radioactive and dangerous, but natural uranium before exploding is mostly safe and it won't explode unless you enrich it and set up the correct conditions.

[–] Badabinski@kbin.earth 12 points 1 week ago (1 children)

Tbf, uranium is intensely toxic even if it's not very radioactive. Shit's like turbo lead, it's a crazy heavy metal.

[–] FooBarrington@lemmy.world 6 points 1 week ago

"Turbo lead", I love it! That means we can use it to make turbo sweeteners, right?

[–] chelatna@sh.itjust.works 7 points 1 week ago

I think beryllium is scary. Inhaling the dust gives you berylliosis 😮.

Hiroshima, Nagasaki, Chernobyl

I was being facetious lol

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

I hate how he did that comic because the sign faces the wrong way. the audience is the one who needs to read it!

[–] howrar@lemmy.ca 3 points 1 week ago (1 children)

maybe it is, we'll never know!

[–] leftzero@lemmynsfw.com 2 points 1 week ago

It's safe as long as you aren't in daily constant contact with it or eat it.

Let me hit you in the head with a 5kg chunk of U-238 and then tell me it's safe.

[–] merc@sh.itjust.works 2 points 1 week ago

Yeah, they even show a periodic table. On that row, Uranium is just about the safest "rock".

It's even mostly lickable.

[–] lordnikon@lemmy.world 8 points 1 week ago

More than just one

I think I crafted this nugget in Schedule 1. Uranium Thunderfuck Cookies

[–] Mora@pawb.social 4 points 1 week ago

But what I need to know: which stone can people turn gay or trans?

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

Wasn’t there a storyline where Lex Luthor got terminal cancer from wearing a kryptonite ring all the time?

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

That was also in the Bruce Timm animated series. The first crossover with Joker teaming up with Lex where he stole a "Jade" dragon statue that supposedly killed it's owners with a curse was actually made of Kryptonite and later in Justice League Unlimited had Lex diagnosed with cancer I think. Kryptonite has always been hazardous to humans.
