While digging around the storyboards of Iron Lung this clip for the intro showing AT-5 and the blood ocean caught my attention. First of all the design is harrowing, evoking the imagery seen later of the Red Eye in the Void.

From these images (brightened and contrast reduced to see the full sphere beyond the terminator) and area calculations we can tell the ocean only covers 3.6% of the surface and the 'moon' has an atmosphere, one that's a similar color to our nitrogen-oxygen atmosphere. In order to accommodate the ~100C surface temperature required for the blood ocean it would need both significant temperature and significant gravity to maintain such a warm atmosphere without a sun.

The remainder of the surface seems to be solid but very reflective, perhaps a metal of some kind which would add significant mass required for gravity and atmosphere and reflect heat back into itself. Another possible factor could be an extreme rate of rotation which would increase temperature and lessen perceived gravity at the equator but contribute to shedding of atmosphere much faster (but as they've likely only been around since the quiet rapture we may not have to worry about the atmosphere shedding any significant amount). @dessathealien I could easily see your white hole being located at the center of this Eye-like ocean and the way it parallels the being seen in the void is uncanny.

@negative-pressure-ventilator confirmed the map in the film uses meters for scale, and is 600x600m for the initial scan. The extended map for the cave system goes out to x:1100 and up to Y:950, the blood ocean has a diameter of at least 1km but likely much more.

I'm a bit too tired to do more calculations about this tonight but I wanted to get it out there for other people to look at!

Tacking on some of the AT-5 calculations I've had sitting in my notes:

Assuming that the temperature of the Blood Ocean is similar to the average human body temp (37°C/98°F), the minimum atmospheric pressure of AT-5 would be about about 7.1 kiloPascals or 0.07% the density of Earth's atmosphere. Any lower and the ocean would boil at 37°C. If Deadlymelodic's design for AT-5 is canon (and god I hope it is the eye imagery is fucking perfect) and the atmosphere is that visible from space, then I'd lean towards the atmosphere being a bit denser, maybe 30-50% the density of Earth's atmosphere.

Without the gravitational acceleration to work with or any reference for scale, it's difficult to say exactly what the size and density of AT-5 is. If we were to say that the Blood Ocean has a diameter of 1 km and that AT-5 has the same gravitational constant of Earth, then some very very rough math gives us a mass of like... 4.08x10^11?? The circumference would be like 17km though which is INSANE, so I think it's safe to say that the Blood Ocean is a whole lot bigger than 1km.

So many variables, so few answers.

Holy shit.

I fucking love sci-fi interplanetary pseudoscience. One of my favorite video games of all time is No Man's Sky.

Oh man, I wish I was smart enough to do these kinds of deep-dives myself. I'm fantastic at character stuff but when it comes to things like this, I get lost.

You guys are explaining this in a way that is so much easier to understand. I'm geeking out right now.

I like to think AT-5's atmosphere is not breathable because it has too much oxygen - and would cause oxygen toxicity. That the ratio of oxygen to nitrogen isn't the same as ours.

I also wonder what the space stations are like. I've been imagining Deep Space 9 kinda stuff, but if we're going a bit harder on the science, they're probably like the ones in The Expanse where they generate gravity by spinning (or hollowed out asteroids and dwarf planets). In The Expanse, generations of people born in space developed different body types, with Belters especially becoming tall and having frail bones (those are people in the asteroid belt).

I still defend Simon was likely born on Mars because of some dialogue I heard in the movie. ("They have a tree. It will feel just like home. Simon, don't be like that.") Mars' gravity is 38% of Earth's. That's probably more than AT-5's gravity.

We would feel very light on AT-5. But I think Simon is not used to a planet's gravity anymore, even if he was born in one. Not even a moon's gravity. He has the bone density, but his muscles aren't used to it. He probably felt heavier in AT-5 than he ever had in a long time.

Would explain why in so many scenes he's walking around stretching his arms and shoulders. Would add up to how tired and pained he looks.

And, @ctrl-shift-alt-9 , that would explain why your wires guy Michael is much taller than Simon despite being probably the same age! Being born and growing up in low G would do that!

As bonus, I have a personal headcanon that Simon uses that harness under his shirt as a back posture thing because of the low gravity. And uh, your guy is wearing at least 15 harnesses.

/silly

No, wait, hold on, wasn't it your headcanon that he was tired all the time? Imagine how crushing a moon's gravity wouldn't be to someone born and raised in space?
