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

    Even when the impulse drives are down, the ship always just stops 🤷‍♂️

    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.

    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. 🖖

    Did you steal this from Dr mccoy's Facebook?

    Oh I'm sorry, is a ship's head medical officer with decades of experience treating a dozen or more species of crewmen and guests not a good enough source for you? Don't let those pointy eared bastards fool you. They're devious.

    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.

    Wasn't there a Tom Scott guest video where some person investigated the effects of stale air with medical supervision while Tom Scott was on some sort of break

    https://youtu.be/1Nh_vxpycEA

    I think the person displaysd effects similar to being drunk after a while on stale air

    Now multiply that space for every person on the bridge

    I think they might actually be in fluidic space and just really unobservant.

    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!)

    Yep, everything is in freefall orbit of something bigger.

    What if you are in the gravity center of the universe?

    i think that would actually be the case most of the time.

    you don't care about anything outside the observable universe and inside that bubble, the cosmological principal would apply, stating that on a large enough scale, the universe and distribution of matter in it is considered homogeneous

    so unless you are in close proximity to some local gravitational source, i think you would be generally affected by roughly the same gravity from all directions.
