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

[–] [email protected] 17 points 3 days ago (3 children)

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

[–] [email protected] 13 points 3 days 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..

[–] [email protected] 7 points 3 days ago

Exactly. Sling yes, pebble no

[–] [email protected] 4 points 3 days ago (1 children)

To a giant, that's a pebble. 😌

most pistol bullets are pebble sized for humans

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

[–] [email protected] 4 points 3 days ago (1 children)

lower centre of gravity, less chance of toppling over

[–] [email protected] 3 points 3 days ago

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

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

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

[–] [email protected] 2 points 3 days ago

I mean... more than Goliath.

[–] [email protected] 4 points 3 days ago

I like that

[–] [email protected] 2 points 3 days ago (1 children)

What if your plan includes getting hit with a rock

[–] [email protected] 1 points 3 days ago (1 children)

Then their plan is complete

[–] [email protected] 1 points 3 days ago (1 children)

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

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

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

[–] [email protected] 32 points 3 days 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.

[–] [email protected] 13 points 3 days 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 2 points 3 days ago

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

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

[–] [email protected] 1 points 2 days 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.

[–] [email protected] 1 points 2 days 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.

[–] [email protected] 11 points 3 days 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.

[–] [email protected] 5 points 3 days ago

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

[–] [email protected] 6 points 3 days ago

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

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

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

It's even mostly lickable.

[–] leftzero 2 points 3 days 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.

Hiroshima, Nagasaki, Chernobyl

I was being facetious lol

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

maybe it is, we'll never know!

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

[–] [email protected] 8 points 3 days ago

More than just one

[–] [email protected] 4 points 3 days ago

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

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

[–] [email protected] 3 points 3 days 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.
