Turns out it'd be a dissapointingly small sphere:

US annual defence budget = $800 billion

2% = $16 billion

Obsidian cost per kg = $5

Total kg in budget = 3.2 billion kg

Density of obsidian = 2.6 g/cm3 = 2600 kg/m3

Total volume of sphere = 3.2b/2600 = 1230769 m3

Volume of sphere = 4/3 π r^3

Radius = (3V/4π)^(1/3) = 66.48 m

The sphere would only stand at 133m tall, I propose we instead utilise the entire defence budget for a much more skyscraper like 490m tall orb

[–] MargotRobbie@lemmy.world 73 points 2 years ago

Nobody said it had to be a solid sphere, how else would you get it to emit the ominous hum without attuning its natural frequency by carefully designing the thickness of the obsidian layer?

[–] lseif@sopuli.xyz 68 points 2 years ago (1 children)

ignores engineering and construction cost. but we can assume that all people involved would work for free, because its a massive honour

[–] Confused_Emus@lemmy.world 7 points 2 years ago

Obsidian Orb is really Roko's Basilisk. Allowing you to live is your payment for building it.

[–] pokemaster787@ani.social 41 points 2 years ago (1 children)

Well that's assuming it's completely solid and not hollow. Hollow would probably be pretty huge, although the structural rigidity might not be great. Maybe we make a giant obsidian 3D printer and print it at like 10-15% infill.

[–] peopleproblems@lemmy.world 26 points 2 years ago (3 children)

An obsidian 3d print is less crazy than you might think. It's essentially rapidly cooled lava.

Need something to hold the lava, then pressurize it to squeeze it through a nozzle that that has attached cooling units.

[–] ivanafterall@kbin.social 12 points 2 years ago (1 children)

I think you just described a volcano.

[–] cram42@lemmy.world 10 points 2 years ago (1 children)

Simple: bucket of lava, bucket of water, repeat.

You're assuming one year of budget. I take it as 2% per year and something of that size would likely take 10+ years to build out.

This guy orbs!

[–] BarrierWithAshes@kbin.social 28 points 2 years ago (3 children)

It would also crack instantly. Obsidian's not durable.

[–] lseif@sopuli.xyz 47 points 2 years ago

yeah right. it takes a long time to mine, even with a diamond pickaxe

Because Obsidian is really fragile. Maybe a bird hits it by accident, shatters the whole thing.

[–] Restaldt@lemm.ee 23 points 2 years ago (1 children)

What if it were egg shaped

[–] Obsidiman@lemmy.blahaj.zone 20 points 2 years ago (1 children)

Then the bird would probably sit on it I think

[–] HeyThisIsntTheYMCA@lemmy.world 5 points 2 years ago

Would it be a pretty bird?

My only question is why we didn't build the orb back in the Eisenhower administration when it was most needed.

Would be a far better use of the 'defense' budget than what they're currently spending it on.

[–] Franzia@lemmy.blahaj.zone 23 points 2 years ago (1 children)

Thats funny because more than 2%, more like 40%, of our defense budget is going into a black orb never to be seen again and is completely unaccounted for.

[–] hibsen@lemmy.world 9 points 2 years ago

I have the feeling that if we shook execs at Raytheon and Lockheed upside down for long enough a fair amount of that would fall out.

It should go on top of Devil Mountain, it has one of the largest viewsheds in the western US.

[–] Confused_Emus@lemmy.world 4 points 2 years ago (1 children)

If we’re ok with relocating it outside of California, let’s put it on top of Devil's Tower and call it the world’s largest Gazing Ball garden ornament.

[–] FlyingSquid@lemmy.world 4 points 2 years ago

No, we should put the quartz one on Devil's Tower and it will be the world's largest crystal ball. Fortunes could be told for miles.

[–] Blackout@kbin.social 16 points 2 years ago (1 children)

Just imagine the size we could build if we used all of the defense budget. It's resonant frequency would blow the eardrums of everyone on the West Coast and kill all marine life. One day when I'm presadent...

[–] Eheran@lemmy.world 5 points 2 years ago (2 children)

I don't think "resonance frequency" means what you think it does.

Why would it hum and am I taking this too seriously?

[–] kakes@sh.itjust.works 26 points 2 years ago (1 children)

That's the best part - nobody would know!

[–] farent@lemmy.scam-mail.me 7 points 2 years ago (3 children)

But even so, if you were wise, you would hum as well.

Large homogenous objects make noise. Most theories i've heard think it's a result of vibration/internal stresses.

[–] Pregnenolone@lemmy.world 7 points 2 years ago

Well because it comes out of the defence budget it would be a military installation and therefore the hum is classified

[–] ipkpjersi@lemmy.ml 6 points 2 years ago (1 children)

I think you're not taking it seriously enough. The number of benefits from this would be immense.

Why wouldn't it hum?

[–] KISSmyOS@lemmy.world 14 points 2 years ago

Why does the government keep this from us?
Why are they so afraid of giving the public what they deserve and want, an ominously humming obsidian sphere?
What if China builds a mysteriously vibrating marble sphere first?
Were all the plans for this project taken to Mar-a-Lago? Or saved on Hunter Biden's laptop? Or hidden in some pizza restaurant?
Just asking questions...

[–] flicker@kbin.social 10 points 2 years ago (4 children)

Something one might propose to build in Night Vale.

[–] acastcandream@beehaw.org 8 points 2 years ago* (last edited 2 years ago) (2 children)

Please do not disregard the obsidian sphere in the Night Vale public swimming pool. Make sure to give it all due attention. But not too much attention, so as to make things weird. Too little attention, unfortunately, will also bring about its ire, and we all remember what happened last time. Simply apply the recommended amount of regard to its ominous, strangely comforting hum, as it gently lulls you to sleep.

And now: the weather.

In 2022, the defense dept spent 590billion dollars, 2% of that would be 11.8 billion dollars. While it is impossible to calculate the cost of constructing this sphere, it cost 25 billion dollars to develop the Airbus A380, and 150 Billion to complete the International space station.

The US defense budget isn't an infinite pool of money. It's 15% of the federal budget. It's dwarfed by healthcare spending (27%), and Social Security (24%). I'm not a war hawk, I try to bring this up in lefty spaces because skimming off the defense budget to solve social problems is a common, and silly belief.

What percentage needs to be cut for it to float in the air and shoot death rays at heretics?

[–] KISSmyOS@lemmy.world 15 points 2 years ago (1 children)

None. That would be part of the defense budget.
