"Every cloud has a silver lining." The saying is fairly well-known, but I was musing on it while staring through a cloud bank, and I started to wonder: What kind of hellhole would a planet have to be to have clouds made out of literal silver vapor?
The first thing that comes to mind is that for silver to become a vapor, the planet would have to be unsurvivably hot. It would also need an atmosphere composed of gaseous elements heavier than silver, for that silver to have any buoyancy. Already this planet is totally unsurvivable for all imaginable carbon-based life forms, but how much worse would it actually be? Is such a planet even physically possible? And what kind of insane conditions would it contain if it were?
