If you are here asking: "Is this a science meme?"
Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.
Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.
We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.
See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

The only real purpose of the lithium deuteride is that it's a dry, shelf-stable, room-temperature fuel. The very first hydrogen "bomb" (actually a building-sized device) used supercooled liquid hydrogen as the fusion fuel, but this was obviously not practical for a deliverable bomb.
I get that part, it's still the reaction I can't wrap my head around mainly because I don't understand how chemistry is any different than alchemy.
I know that lithium itself doesnt fuse to create He+T+D, and I know it can't undergo fission. Since lithium isn't left over, and lithium-6 and 7 are stable, does that mean the neutron with extremely high kinetic energy really knocks like two of the LiD mokecules into each other, causing dueterium -dueterium fusion resulting in He4, and the Li6 gets more neutrons that for it to be come unstable enough to decay into tritium or deuterium?
