Platystemon posted:You don’t need an atmosphere at all to have “burning”, though. Some things contain their own oxidisers. Gunpowder, for instance. You could fire a gun on the Moon if you wanted because the reaction doesn’t require outside oxygen—it couldn’t, because then the reaction couldn’t happen fast enough. In gunpowder’s case, it happens to contain actual oxygen, but there are plenty of explosives that do not. Silver azide come to mind, it just comes apart into pure nitrogen gas and silver dust. drat! So you are saying that spaceships could fight each other by using muzzleloaded black powder cannons  ?
