­xkcd thread

The video invokes a magic spell that teleports the money to you. But done correctly, it will teleport just the money, and not the smelly gunk and crud adhered to the money or even infused with it. So really it should just smell like metal or paper.

Nothing like that new-money smell.

Not watching a video. Any spoiler? Would it end up being enough mass to make the base really hot? Sterile so not a compost pile..,

It’s under 3 minutes. But in short, it would spread out like the Great Molasses Flood of 1919, killing thousands, or if you made a building for it (like Scrooge McDuck) it would violate building code by exceeding ground pressure limits.

Turns out teleporting an enormous pile of coins to a place near you is a bad idea, because coins don’t like to be in a pile and they will crush you. More to the point, everyone else will just start using other means of exchange rather than acknowledging you as sole owner of all the world’s wealth.

I’ve speculated about a worst-case scenario regarding dark matter– or rather, the anomalous movement of galaxies and galaxy clusters that is presumed to be caused by dark matter. It’s basically, what if we never find anything? No experiments confirming new weakly interacting particles. No new heavy particles turning up in colliders. No verifiable extensions to the Standard Model, and all the hypothetical extensions are purely ad-hoc for the sole purpose of predicting dark matter. What if postulating “dark matter” contributes no more understanding than saying “a wizard did it”?

What if the anomalous movement of galaxies and galaxy clusters is simply a hole in science– forever? What would be the epistemological consequences for a defeat of science on that scale?

It’s sort of bound to happen eventually. At a certain point our particle accelerators won’t be able to probe deeper and our cosmological observations won’t get any better. We’ll have to throw up our hands at that point and say physics is done. Maybe we’re already there but we should probably give it another couple centuries to be sure.

Orbital-size accelerators. We already got the vacuum; all we need are the guide magnets.

With current technology you’d need an accelerator the circumference of the Oort Cloud.

Good bet by the time we could build one out in the Oort cloud, our tech will have improved a wee bit.

But your point stands; we’re stuck back in Kansas, Toto. Oz is a long, long, long way away. In time and in space.

The problem is that the predicted unification energies (let alone Planck scale) are so ridiculously high that mere tweaks don’t even begin to cover the orders of magnitude we fall short. We’d have to be able to accelerate particles by Oh My God energy levels per nanometer over hundreds of kilometers to even get close.

But the point of the comic is beyond that: it is what if knowing more is not just technically impossible by any imaginable scale, but fundamentally unknowable?

But even more fundamental is that there might not be a difference between those things.

You can say that it’s impossible to measure the position and momentum of a particle with perfect accuracy because any means of probing it must perturb it slightly. You can also say that it’s a fundamental characteristic of quantum mechanics arising from the nature of waves.

But those are exactly the same thing! The characteristics of the universe limit what can be technically achieved. And there’s no reason to think there’s anything more fundamental than that.

I’m not sure we’ll ever really know what goes on inside of a black hole because I’m not sure there is anything inside one. Since nothing comes out except for totally scrambled information that lives on the surface, the universe has no obligation to “run the physics” on the inside.

We-ell, not quite that bad. By postulating dark matter at all, even particles that only interact via gravity, we’re still supposing that the ultimate laws of physics describe such particles and that their existence is a result of those laws. Discovering those may be technically unachievable but even that would be better than a “hole in science” like my utterly nihilistic agnostic scenario.

“Frankly, given their extreme gravitational fields and general instability, even 12-inch globes should probably be banned.”

If you’ve got the tech to stably compress an Earth-sized mass into a 4-inch sphere, a black hole is really the least of your concerns.

Kids: Spaghetti for lunch again?

Thanks, ChatGPT.

I, uh… that’s certainly an image of my post. Gotta give it props for the Strangelovian sunglasses on the kids.

For the record, I was referencing spaghettification:

A tiny, dense object will have strong tidal forces that act to stretch things out in the vicinity (before going splat on the surface). Including the children themselves.

I misread the word “stably” as something to do with stabbing and my mind went to a strange place. :slight_smile:
