      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.

        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.

      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.

    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.

    Gravity is on a separate subsystem & power supply, because without gravity people couldn’t reasonably move and fix the rest of the ship, so even when compared to general life support, it’s the most critical function and the most isolated.

    And production cost.

    On a space station more than a space battle, but Titan AE had a scene that made good use of this. The station is old, and early in the scene the gravity generator goes on the fritz, causing everyone to float until some percussive maintenance gets it working again. When bad guys show up Matt Damon shoots the generator to cause some confusion and let him escape faster by pushing off toward the exit.

    I am a big fan of sci-fi and understand how expensive weightlessness is to film, so combine that with the amount of shows that have been canceled and I completely accept the fact that they try to keep this more fictional than science.

    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.

    Even when the life support systems have completely lost power, everyone is dying, etc. Gravity is the one system too critical to reroute.

    Star Trek VI - The Undiscovered Country did it, even making it a point during the Trial ;-)

    They did in the first episode of Transformers Animated. Granted, that was a cartoon, which made it infinitely easier to have them float in zero gravity than a live action movie.

      That’s the episode where for some reason the Deception jets turn into triangles and after sleeping for 6 million years Optimus wakes and just says “thanks” and throws Teletran-1 a thumbs up and also Casey Kasem is there right
