  • Cooling by radiation is slower than convection or conduction, but it still happens. The James Webb went from room temperature to deep cryogenic in a few months, and it’s big. As for moisture, things cook off into a vacuum very easily. That’s the foundational to the whole concept of freeze drying, actually.

    Freeze dried wood is absolutely commercially available, if pricey. I have no idea if anyone has used it for musical purposes either. There’s a lot of audiophile-ish magical thinking in that space so it’s possible nobody has bothered.

    Edit: Although, since this is a research project, maybe not freeze drying it first was the point.












  • I mean, I’m not just talking about the guns. Imagine you’re at the bank, and then an individual in full tactical gear materializes behind you. He has a substantial amount of ammo and disappears every time he reloads. Molotovs, grenades, hell, you could even fit a flamethrower. You could fit a massive bomb into that space if you wanted. And you could potentially completely escape the effects of the blast inside you pocket dimension.

    Okay, but it still doesn’t take more than one good hit to take said guy down - even in a vanishing tank they would eventually figure out where to direct the airstrike. And the bank would have given him the exact same cash drawer with just an imaginary gun he claims is in his pocket.

    Yes, you absolutely would still get on the radar after a while as a big smuggler. Or whacked by a rival in your chosen organised crime group or insurgency. A Western government couldn’t really charge you with smuggling unless they can prove you have magical powers, though, and they would have to try and catch you doing something else illegal instead. The one exception I can think of is if you figured out something you can be the end consumer of, as well, but I don’t know what that would be.

    Edit: Although, bombing might be an idea. You could fit a couple week’s supplies and and a car bomb amount of explosives in there, no problem. I doubt it would be more lucrative or safer than smuggling, though.



  • Yes. People seem to think the bends always happens on exposure to weird pressures, but it just doesn’t. I guess they’re understandably imagining it’s the same as hot or cold.

    (though no idea about the effects on the human body from such a sudden change)

    Well, enough delta p is entirely capable of squishing an entire person through a thumb-sized hole, and while there’s no hole here I image there’d still be some sort of shock wave, and the air already in your lungs returning to normal volume suddenly would be uncomfortable. Don’t go too deep the first time, definitely ease into it.

    Interestingly just 1 atm is fairly harmless. The first time someone got caught in a vacuum chamber they weren’t sure what they’d find, but the guy just got up and said his ears hurt.
