• There is an All-around!
  • Nope, however local space is all on a kind of plane, and not spread around randomly.
  • "Up" and "down" are prepositions based on relativity. You are always above and below something, it's all where you percieve the ground to be. In that sense, up and down are all just an illusion, and never existed in the first place.
  • since up and down rely on gravity and in space there is none.... nope.
  • there's no up or down here either - there's only toward or away from gravitonic pull.
  • Maybe only relative to where you are but not really. Reminds me of the Star Trek movie where Kahn is only thinking in 2 dimensions; of course, Spock points this out.
  • 1) "In space there is no up or down and there is no gravity. As a result, astronauts are weightless and can sleep in any orientation. However, they have to attach themselves to a wall, a seat or a bunk bed inside the crew cabin so they don't float around and bump into something." Source: 2) "The interesting part about working inside the Progress is that there is no "up" or "down" direction inside. There really isn't an up or down anywhere else here, but there is a direction we think of as the floor and a direction we think of as the ceiling in each module. Most of the labeling on panels and equipment is written so that it is right side up assuming this orientation, and also most of the lights are on the "ceiling" so they cast light "downwards." To add to the effect, there is a simulator back on Earth we spent a lot of time in where we got used to one direction as the floor and the opposite direction as the ceiling. So up here, when Yuri and I say downwards or upwards, we mean the equivalent directions as in the training module on Earth." Source: 3) "[edit] In space there is neither "up" nor "down" Artificial gravity is a staple technology in science fiction. In the depths of space, there exist no reference points to establish which direction is "up" and which is "down"; therefore, on board a starship, the sense of direction can only be provided by the artificial gravity. Why then, do sudden course changes or impacts upon a ship toss the crew members to the floor? (From a viewer's standpoint, this is because having crew members thrown about during a battle makes for a more dramatic effect, as well as the difficulties of depicting starship life on an Earth-bound soundstage.) Response: The standard Star Trek explanation invokes inertial damping fields. Without some sort of dampening field the sudden acceleration involved in space would cause objects in the ship to be instantly flattened. To avoid this, the ship has a force field that counteracts forces due to acceleration. The strength of this force field must be constantly updated with the ship's current acceleration. However, if the ship encounters an unexpected acceleration or force, the calculations are momentarily incorrect, and this causes a shudder, as the damping fields are momentarily unbalanced. The Star Trek Technical Manual terms this a "characteristic lag". The unbalanced fields are set up so that they are well within the levels tolerated by human beings, but they can cause people to fall out of chairs. In a scene cut from the film Star Trek Nemesis, the filmmakers added a new captain's chair with an automatic seatbelt function."

  • Space has no direction. Up and Down are concepts in relation to "some point".
