oh good, between this and hypersonic suborbital kinetic bombardment, we're really starting to see some of the weapons ww3 will be fought with! what fun!

The hydrogen bomb can cause extended thermal damage because the white-hot fireball it produces – sufficient to melt aluminium alloys – lasts much longer than TNT’s fleeting 0.12-second flash, according to the paper.

the device uses a magnesium-based solid-state hydrogen storage material. This material – a silvery powder known as magnesium hydride – stores considerably more hydrogen than a pressurised tank. It was originally developed to bring the gas to off-grid areas, where it could power fuel cells for clean electricity and heat.

The chain reaction begins when detonation shock waves fracture magnesium hydride into micron-scale particles, exposing fresh surfaces, according to the study. Thermal decomposition rapidly releases hydrogen gas, which mixes with ambient air. Upon reaching the lower explosive limit, the mixture ignites, triggering exothermic combustion. This liberated heat further propagates magnesium hydride decomposition, creating a self-sustaining loop until fuel exhaustion – a synergistic cascading of mechanical fracturing, hydrogen release, and thermal feedback, according to the paper.

doomer fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuck

I dunno about you, but I'm resting pretty comfy with the knowledge China has these; as I see it the only downside is that chances are, Russia, North Korea, Iran, Yemen, and even the Palestinians and whoever else in the global south might desire them, does not also have them.

By all means, if the west truly cannot accept coexistence even with the promise of MAD hanging over their heads, and if they truly push things to WW3, then their slate (of "civilization," if unparalleled brutality and greed can be called that) should be wiped clean if you ask me. Such is deterrence, but frankly as someone living in the west it may as well also be considered a mercy, over leaving the survivors at the mercy (or complete lack thereof) of an unchecked western capitalist hegemony.

absolutely my biggest concern here is that the west is able to copy this technology. but while on the one hand i completely agree with you, on the other hand i'm also not looking forward to this getting dropped nearby when the ruling class of my country inevitably makes the decisions that capital dictates they must.

here's the thing. this lowers the bar. non-nuclear weapons that can achieve similar effects to nuclear weapons are going to get used (as oreshnik has already been used). as @plinky@hexbear.net says, these aren't much worse than conventional explosives, so why not use them? it's not mutually assured destruction with these weapons, not in the global civilization ending sense, so we're back into the realm of tactical ballistic exchanges being a weekly or monthly occurrence.

i really don't like where all of this is headed.
