    Any chance you know the canon explanation of how they counteract the gravity generated by the Deathstar’s mass?

    • thejml@lemm.ee ⁨1⁩ ⁨month⁩ ago

      How much gravity would the Deathstar’s mass provide? I feel like it would be very small considering it has no real massive central solid or liquid core.

      The gravity is negligible. The official sizes of the Death Stars have been 120 - 900 km in diameter according to rebel scale. For comparison Earths moon is ≈35000 km in diameter and it’s gravity is 1/6 of earth’s. On top of that, the Death Stars are mostly hallow, being a metal framework, instead of solid rock.

      It doesn’t create enough gravity because it isn’t massive enough to create gravity. They use gravity deck plating.

  I know we’d all like some scientific actualisation of Star Wars but I mean:

  • They made noise in space 'cause that’s fun.
  • There was always gravity on pretty much any ship.
  • I don’t really recall any spacewalks so we don’t see any instance of 'no gravity’
  • There’s hyperspace since lightyears is a bit of a long time.
  • Stormtroopers seem very scientifically and inefficiently accurate

  At this point I think the Star Wars movies (the oldies) pretty much ignored a fair bit of the science.

  But if it was a death star literally put there in our universe, I think there would be a bit of structural considerations for gravity, but not huge due to it being quite hollow. Gravity is pretty strong when the sphere is entirely comprised of dense rock and no air. A mostly hollow sphere of air where air is something close to 1/1000 that of rock (yes, used the density of water lol) is not going to get much of a rollicking from gravity.

      My headcannon for this is that spaceships in that universe are to those people what cars are to us. If you know the basics of driving a car, you can drive most cars, though the bigger ships might get more complicated (I’ve never seen one of our heroes try to back up a star destroyer into a starbase to help with their buddy’s move.)

    Good call on it being mostly air.

    FYI for soil air is ~1/2000 the density.

    There was always gravity on pretty much any ship

    And if the ship got damaged where the nose started falling (downward?) the gravity would shift towards the nose so that everyone went sliding across the floor.

    • MindTraveller@lemmy.ca ⁨1⁩ ⁨month⁩ ago

      That only happened near planets.

      Star Wars ships don’t orbit. They simply hang in the sky, in much the same way that bricks don’t. In Star Trek ships orbit to save on fuel costs while parked near a planet. But in Star Wars antigravity is so cheap that it’s more efficient to be stationary relative to the planet’s surface. Which means no microgravity.

They have super advanced AI robots tech, they can regrow a hand in a day, no more disease and live 257, transport living moving organisations across great distances, have developed telepaths and telekinetics, and can fold space-time, but are fucked if they can shoot straighter than a drunk badger with one ‘arm’, balancing on a log going down a rapids!

    • Tarquinn2049@lemmy.world ⁨1⁩ ⁨month⁩ ago

      Yeah, the fact that we already have the technology to make a gun that handles the aiming for you… and we aren’t even shooting light, which would be even easier to auto aim. Fights should be super short and boring, one shot, one kill… 20 shots, 20 kills. There would be no action heroes because very few people would ever live through more than a handful of fights. The heroes would be the beurocrats, so we’d have to spend alot more time watching them.

      Sounding like they made the right choice.

    This is just my head canon, but the noise actually comes from speakers on board the ship /in the cockpit, to help give the pilot an audio cue as to where hazards are around them.

      I don’t deny the star wars universe is getting a bit more of an update in the cinemas, especially post-Interstellar and whatnot, but space opera in the 80s was really intent on ignoring the stark reality of space for both constraints of filming and viewership. Goddamn fun though.

      source
    • lolcatnip@reddthat.com ⁨1⁩ ⁨month⁩ ago

      Spacewalks are a bad example anyway. A ship’s artificial gravity could extend outside its hull. Conversely, the lack of spacewalks doesn’t mean we aren’t shown the absence of gravity, since we see the ships themselves maneuvering in a way that suggests a lack of gravity.

      Gravity in SW is still kind of fucked, but not “gravity in deep space” fucked.

    I think the animated shows had a few more space realistic moments like space walk repairs and such.

    Best battle scene in the whole series from clever tactics PoV IMO was Anakin deploying his artillery into a planetary ring system and then using his capital ship to bait Greivous into a pin between the ring mounted tanks and the capital ship.

    Best battle overall is obviously the siege of Mandalore just for the absolute knockdown drag out chaos in the middle of a domed city megastructure that’s probably meant to be a seed for an eventual ecumenopolis.

  Besides technical diagrams, the Falcon lands in a docking bay that’s oriented towards the first option. There could be some kind of transition point to the second option, but we don’t see it and it’d be really awkward.

  source

  Both.

  The Millenium Falcon landed in a bay that was oriented with the N/S axis of the station, but was accessed on the equator.

  The surface cannons, surface towers, and trench defenses were all radially oriented with “up” pointing out into space, like you’d expect on a moon.

  This also suggests the station was littered with gravitational dead spots and areas where you’d have to carefully transition from one gravity well orientation to another. No wonder everyone is wearing a helmet.

  • DragonTypeWyvern@midwest.social ⁨1⁩ ⁨month⁩ ago

    One of the reasons Star Wars gets called space fantasy is that these objectively cool scenes to shoot simply never make it into the movies because no one even thought of these details in the first place.

    Imagine how cool a lightsaber duel would be in these gravity transitional areas, or zero g for that matter!

      The one thing we can really say for sure is the gravity tech is everywhere and apparently crazy reliable.

      I love holding this fantasy nonsense up to scrutiny. I just falls apart in the most humorous way possible.

      For instance, here’s a checklist for technology mastery in a galaxy far, far away:

      [x] Antigravity
      [x] Practical FTL travel 
      [x] Practical interstellar navigation
      [x] Energy weapons capable of destroying things at _any_ scale
      [x] Energy shielding
      [x] Laser. Swords.
      [x] High energy physics in general
      [x] Self-aware artificial Intelligence
      [x] Multicultural society spanning many worlds
      [x] Psychic powers, telekinesis
      [x] Pocket-sized SCUBA gear
      [ ] Materials capable of resisting laser swords
      [ ] Functional galactic government
      [ ] Counter-intelligence for said government
      [ ] Basic spycraft for said government
      [ ] AI that's good at lie detection
      [ ] Spaceborne capital ship battles
      [ ] Large space-stations without critical weak points

  Probably A. It would likely have used artificial gravity just like any starship. Star-Trek has it built into the deck plates but I dunno how Star Wars does it. Artificial gravity can then be dialed in to compensate for the natural gravity of the structure. Which is probably less than you’d think. Without normal gravity effects, the internal air and water pressure will be mostly uniform across the ship instead of denser towards the core.

  Same with the matter making up the structure. It’ll largely be hollow and filled with air, so much lower natural gravity than an actual moon of the same size. According to official sources (referenced here: …stackexchange.com/…/is-the-death-star-s-gravitat…) it’s between 120 & 160 km radius, for a probable gravity of ~0.04g. That’s not quite microgravity, but still far too low to be walking around in. For comparison Lunar gravity is ~0.166g.

  i don’t know much about star wars, but wouldn’t gravity be weaker near the centre as you’d have less mass below you and more above you

  source

  • Staubsaugernasenmann@discuss.tchncs.de ⁨1⁩ ⁨month⁩ ago

    Assuming the mass is evenly distributed the mass above you doesn’t contribute any additional gravitational force. The mass above you can be described as a hollow sphere. Inside such a sphere all gravitational components cancel out. So its just important that less mass is below you

  B if their antigrav is like 2001 a space Odyssey. A if they’re using local gravity (eg built in the gravitational orbit of something).

  So depends where it was built.

  Either way miniaturization is what they really need to focus their efforts on.

  Hell, they’d save a lot of space if it were an unmanned drone. Which is also true of Elon Musks schemes to get to Mars.

  Judging by their ships, they have gravity generators which are small enough and have a small enough ration of energy consumption to energt generation to be used in something like the Millenium Falcon.

  Which would mean that from an Engineering point of view the option on the left would be perfectly feasible.

  On the other hand it does make some sense to structure a combat vehicle as an onion with more mission critical sections inside were they are better protected and less important ones on the outside.

  That said, in the Star Wars films we can see that the ship hangars with access to space have a “side” open to space and the “floor” side perpendicular to the radius line of the Death Star, which is consistent with the left side option and inconsistent with the right side one (where the opening to space would be on the top).

    Judging by their ships, they have gravity generators which are small enough and have a small enough ratio of energy consumption to energy generation to be used in something like the Millenium Falcon.

    Indeed and it’s quite clear that the Falcon has two gravity planes perpendicular to each other: 1. the plane that supports everyone on the main deck (cockpit, crew lounge, etc.) and 2. the gun battery gravity plane at 90 degrees. This is easiest to see in A New Hope during the TIE Fighter battle in the escape from the Death Star. Han and Luke are sitting back-to-back, separated by a short corridor that sits perpendicular to the main deck. I don’t think most people notice this because it’s not obvious.
