    The problem with that really is that on a gas giant the physics are a nightmare- gravity is unlivable, by the point in the atmosphere you get to dense-enough fluid to float anything, it’s extremely hot and turbulent. If you dropped a modern submarine into Jupiter’s atmosphere, by the time it got there it would be molten and well beyond its crush pressure.

    On Earth, the pressure/density point (in water) that will float a boat occurs at a low enough pressure and temperature to be survivable by life as we know it- but on Jupiter when you’ve got to the point that it’s dense enough to float anything, it’s also hotter than the surface of the sun.

    Cloud City on Bespin is a super-cool concept but realistically nothing like that can work on a gas giant unless your sci-fi universe also provides magic antigravity to keep the gravity-well from crushing you lifeless.

      Well yeah, I wasn’t expecting something like this to be practical in the real world.

      Maybe if it were a civilization of creatures with exoskeletons, low height, and a low surface area to volume ratio (think fleas, ticks)? Probably still not. It’s just completely unfeasible for humanoids.
