    Pretty sure the warp drives need continuous power to contract space in front of the ship and expand it behind the ship to allow faster than light travel

    The ship isn’t actually moving during faster than light travel, it just bends space around it

    They can only move at impulse speed without engine output due to their being no friction and gravity in space

        My favorite bit is how when life support goes offline, it’s like they’re running out of oxygen within seconds. I once saw the math referencing the actual canon dimensions of the Enterprise D and its canon crew complement. It’s comically large for the number of people in it. You could shut off all the CO2 scrubbers in a space that cavernous, and it would be months before the crew began noticing any ill effects. The Enterprises are god-damn ginormous.

          I recently saw a DS9 episode where O’Brien said life support is down and it’s going to be a problem in a day or sth, was pleasantly surprised at that.

          Might still not be accurate, but at least it was not a “oh shit we’ll die now” kind of thing.

            It depends. Lack of air circulation can cause problems in minutes as people can end up breathing stagnant air. Less of a problem if you have artificial gravity as then you have convection and/or the coriolis effect to help keep the air moving. As for actually running out: less of an issue.

          It’s the Vulcans. They actually respirate at 1000x the rate of humans. It’s how they remain emotionless. They are too focused on breathing to get angry. The massive compression necessary to breathe that much is actually how they are constantly so full of hot air. They don’t actually need to breathe that much to survive, but they are just too proud to give it up even in an emergency situation. It’s all a weird power play. 🖖

          I mean, technically all space is fluidic space. The interstellar Medium is a fluid. It transfers pressure waves, has a temperature, has a density, even a viscosity.

          https://en.wikipedia.org/wiki/Interstellar_medium

          Normally you can ignore the drag from the Interplanetary or Interstellar media, but if you had a ship that could travel at high relativistic speed, pushing past 0.9c, 0.99c, 0.999c, etc., you actually would have to consider the drag from it. Ships going that fast would have to be designed with aerodynamic principles in mind, just like atmospheric craft.

            This is new and surprising to me. Do you have a source? It seems to me that if it gets to a point where you need to design your ship using aerodynamic principle, you should also be able to drive your ship using aerodynamic principle (i.e., push on stuff around the ship, instead of expelling propellant from the ship as usual spacecrafts do).

              I suppose if you could develop some type of sci-fi magnet ram-air funnel thingy you could make something work with the hydrogen atoms drifting around, but you’d still have to jet something out the back to keep going. Less like a rocket, more like an airplane.

      There is definitely gravity in space! It just doesn’t feel that way because there’s no ground so you’re mostly in free fall which to you is indistinguishable from being in no gravity. (fun fact: this indistinguishability is actually the crux of General Relativity!)
