    Simple. All the floors are made from a special exotic material, that is a lot like a magnet, but attracts everything. And just like magnets, they are not powered by any external source and don’t need any external systems to control.

    starships have redundancies most likely, much like the life support systems. its like artificial gravity isnt coming from an actual generator, but the whole ship itself in some unknown mechanism, most scifi genre dont explain how its being created, it looks more like an energy field throughout the whole ship generated from every “system” in the internally.

      Which is fucking cool because it’s one of the few space travel things that really does work. Like if we can figure out the fuel/propulsion thing and some kind of equivalent to deflector shields (not for space battles but for all the random shit in space that could destory your ship in a collision, especially if we get up to relativistic speeds), we could have space travel where you can walk around normally on the ship.

      Also the gravity increasing ships like Goku used in DBZ, so we could actually have someone doing extreme gravity training while en route to a big fight.

      And it works for both acceleration and deceleration, only difference is you’re either travelling up or down.

      Also loved the special seats they used when doing combat maneuvers. ST didn’t just make up artificial gravity (since their ships moved forwards rather than up), they had inertial dampeners, because the evasive maneuvers would have been much more dangerous than the shocks from getting hit.

      ST is more rooted in science than SW, but parts of it are just as much fantasy as the force, which was depressing to realize when you’re hoping for humanity to eventually go in that direction. The biggest human tech fantasy in the Expanse is an engine upgrade that gives improved thrust and efficiency. Not to light speed, but just by like an order of magnitude. And they’ve even got a brutally realistic scene about the discovery that was great world building imo.

        To be fair; if you could build a fusion torch and fully direct the flow; aneutronic fusion fits the bill; the thrust numbers they are using are not crazy.

        You would use stupid amount of fuel to get that much delta-v; but with advanced reactors using readily available fuel sources…maybe not an issue.

            Indeed.

            Total energy available is higher, but that reaction produces radiation as the primary product. Radiation is difficulty to properly direct.

            Fusion (aneutronic) produces the bulk of the energy as charged particles, which we can direct with magnetic or electric fields.

          Yeah, it’s not even that much of a stretch, like that future could be within humanity’s reach. Not sure we’d actually want that particular future, but there’s just something about realistic sci fi that makes this reality feel cooler.

        I mean, gravity is just acceleration anyway.

        Weird fucking acceleration due to the curvature of spacetime and how shit moves through time. But still, just acceleration.

    Gravity is a very dense liquid. Generator makes it in big batches at a time and it just stays there for long even after the generator is gone. After the battle is done and everything is repaired, they just top up the pool and all is good.

    Admit it, you wanted to ask which movies and shows have done it. Instead of asking for people to tell you what the correct answer is, it’s far more effective to post the wrong answer, and wait for the flood of answers to arrive.

      Or Star Trek: First Contact, when Picard, Worf, and redshirt Neil McDonough test out their zero G combat training, further cementing the fact that Star Trek only remembers that space has no gravity when it’s relevant to the plot.

        They do throw things out the airlock an awful lot. Though, somehow, Borg don’t have the strength to stop it but Beverly Crusher does.

            My wife abused star trek of being a soap opera at some point. At first I thought, maybe she’s just showing up at the worst possible time?

            No. It’s all of the time. Every episode has some weird soapy bullshit. Beverly fucking a ghost, LaForge fucking a hologram, Riker fucking anything with genitals INCLUDING a hologram. Everybody be fuckin. That’s not even the soapiest thing. Voyager is basically Soaps in space.

            I love classic trek, but guys I think it’s a soap opera.

    Doylist explanation: it would be too expensive for the FX department.

    As it happens, the same worldbuilding project I mentioned in another post here sort of addresses this. The same aliens mentioned there don’t use artificial gravity at all. Being arboreal creatures they’re well suited to microgravity and can happily live permanently in zero G. Upon meeting humans and learning that we want artificial gravity (specifically centrifugal gravity), they wonder why we spent all the effort to get away from gravity only to spend even more effort to bring it back.

    Since human orbital colonies take the form of O’Neil cylinders, you can cut off the gravity by halting the cylinder’s rotation. If stopped abruptly enough this would cause a lot of damage initially as objects go flying. It would also put the terrestrial, bipedal humans at a disadvantage compared to the aliens with five prehensile extremities.

      This is covered in the Attack Pattern Trunks web comic. If I remember correctly it works even when all power is disabled due to thermal power or some such, I’d have to go searching through all the episodes to cover it.

      I’m glad somebody else caught this, it always irritated me in Enterprise when they insisted that it was a gravity generator and not just plating.

        i think its plating for trek, thats why you can turn it off in some areas and not others. cant say the same for other shows, they likely use a similar mechanism.

    That’s why I prefer hard SciFi like The Expanse books, where science is a main driver to life and motivations to drive the story.

      Not magic. The artificial gravity stabilizers are directly enhanced by the production budget stabilizers, which keep them in check.
