Can someone lay out for me why low pressure is more dangerous than high pressure? In the sense that being in space is rapidly a bad thing, but we can dive to many many times atmospheric pressure if we do it right.
Space: The difference is 1 atmosphere to 0. Dive: Let's say the difference is 1 atmosphere to 10. Space bad, diving ok.
My fan theory is that there is nowhere we would run into an effectively 0 pressure environment at any time during life developing to us being alive. While there are depths and reasons to dive them all over the place.
Pressure drops below a certain threshold and oxygen that's being transported in the blood stops getting to where it needs to go because it's not longer under the pressure it needs to be under in order to be transported. Structurally you'll be fine unless you try to hold your breath and you'll be usefully conscious for 10 seconds or so. But after that things go rapidly downhill.

You know what's a good movie though? 10 Cloverfield Lane.
I've been on the receiving end of people nitpicking about TLJ things that don't make sense and I think I've landed on this now:
It's a matiné film, a noon-on-saturday adventure movie like Indiana Jones. It has that specific style in droves. To be a standout excellent film in that mold it doesn't need to make any sense at all. It's just a great adventure.
but great adventures kinda do have to make a little sense? otherwise it's not... an adventure just a succession of various people doing things for strange and unknown reasons
Nooooooooope
Also it's not like the whole movie doesn't make any sense, there just are several things to talk about.
p much all the conflict and drama made no sense - apart from "I am being stupid solely to create plot" - and that was very hard to ignore
I don't know what specific reason didn't make sense in this particular case since it's a broad point. Like on the broadest possible level to motivate the general set-up, if that's what you're referring to, there was an in movie explanation, maybe not great but it was there.

I feel like there needs to be a more detailed reason for some reason?
Like if you dive to 10 atmospheres and take your blood pressure is it 10 times normal? I feel what I'm lacking is how the body cannot cope with the low pressure, whereas the high pressure is fine.

I actually don't understand the point at all. She's wildly ranked above Poe and why is this the only movie where an admiral is required to explain their plan to a fighter pilot, let alone the whole crew? Not only that but they're facing total annihilation and someone out of the hundreds of people might be inclined to turn coat to save themselves. She should have told an obnoxious fighter pilot 15 ranks below her the secret plan to mitigate him mutineering?
There are a bunch of things I would nitpick but this is one of the points I literally don't understand at all.
Wow I didn't know that according to Wikipedia not adjusted for inflation John Carter is the fifth most expensive movie of all time. That's quite a fuckup

essentially: without air pressure, lungs work in reverse, removing oxygen from your blood. That's the main reason.

This is one of those things where movies have different opinions on how bad it is to be exposed to space and I've never really landed on what would happen.

According to Diogenes Laërtius, when Plato gave the tongue-in-cheek[26] definition of man as "featherless bipeds," Diogenes plucked a chicken and brought it into Plato's Academy, saying, "Behold! I've brought you a man," and so the Academy added "with broad flat nails" to the definition.[27]

They should have just accepted the the chicken as a man and given the chicken a position.

because they actually did talk about it
if they never had the conversation, that would be a lot better but what we got was some utter shite about hope, and not knowing, and how that's important, instead of, I dunno,
for example, "fuck off, I actually have a plan" because she didn't fail to explain the plan she failed to mention the existence of one
incidentally explaining plans is actually most of what officers do, it's kind of the essence of it really. It being a secret was also stupid.

People freezing into icicles in space is bullshit right? Like in the immediate term at least.
IIRC we radiate 100W or something, seems like it would take a long time to freeze just from radiating since there's no medium to float around in.

The risk of high blood pressure isn’t that the number is high, it’s that the difference between inside your circulatory system and outside is high. That differential puts mechanical strain on your heart, arteries, and veins, increasing the risk of mechanical damage to blood vessels, clots forming in damaged areas, clots breaking loose and going somewhere they shouldn’t (embolism, stroke), or failure of a blood vessel’s walls (aneurism), etc.
If you’re in a high pressure environment and the pressure on your whole body is really high, well that’s no big deal. Your tissues are either non-compressible or gas-permeable, so you’ll just adjust to also exist in this pressure. The pressure differential inside and outside all your various tissues should remain constant to what it was at sea level, with no added mechanical strain on anything.

I've also been really curious about what would actually happen when exposed to space
from what I can gather it is 1. explosive decompression of any air you might have in your lungs, do not hold your breath if you want to keep your lungs un-shredded.
2. Unconsciousness from hypoxia in about 15 seconds. Would also blind you.
3. Which I don't think matters much because all the water on your eyes boiling off and probably painfully cooling the surface of your eyes can't let you see good I imagine
4. You start swelling quite a bit. Actually not likely to cause any lasting damage, this. Skin does its job good.
5. Also you get the bends
Your blood pressure would still be good though, because our circulatory system is also very good at keeping blood pressure okay

There’s some evidence that a pressurized air tank and a space suit providing only mechanical body compression with some kind of elastic could keep you alive and conscious in the vacuum of outer space for a while.
