Rocky has an interesting way of raising his pebbles… 👀😂

@Kilof99 Hahaha well chemically inert though nitrogen is, it’s very important for human physiology, just not anywhere near as *urgently* important as oxygen. It’s a rather underrated gas tbh 😅
English
@teestar_writes unrelated but this reminds me of a bit in ben10 I believe where aliens brought a creature to earth that started growing rapidly and became aggressive when exposed to nitrogen and their reaction was basically "you guys breathe oxygen why the fuck is your atmosphere full of N2"
English
I do think it would’ve been funny as fuck in a very morbid “Grace dies the second he opens the airlock cuz of an explosively high pressure gradient” way if Rocky had assumed Grace needed nitrogen instead of oxygen to breathe and flooded the tunnel with 78-kPa N2 rather than O2
English
@magicalounge Not in my universe they’re not!! Them boys are GETTING THEIR HAPPY ENDING 😤
English
coltland twins make me so sad because both are doomed and all i can do is cry about it
English
@Aeryndell @crysanaaru That isn’t actually the only reason. Pure O2, even at the correct partial pressure of ~21 kPa can cause the alveoli in the lungs to collapse and build up with fluid if one breathes it for long enough. Nitrogen is a very important buffer gas that prevents absorption atelectasis
English
@teestar_writes @crysanaaru the book explains that the only reason space stations normally have a full atmosphere of pressure is in case they need to abort and return to earth in a hurry, which isn't necessary in a one way suicide mission. presumably same applies for the actual composition of the air
English
@SierraStriker Standard pressure takes into account the partial pressures of all atmospheric constituents. Earth’s atmosphere is made of ~21% oxygen, ~78% nitrogen, and 1% trace gases. In a given confined space at standard pressure, the partial pressure of O2 is ~21 kPa.
English
@teestar_writes I feel I'm missing something here, isn't standard atmospheric pressure 101 kPa?
English
Good morning, I just saw someone who claimed to be an atmospheric scientist saying 21.1 kPa wasn’t enough pressurization for Grace to breathe in because “humans live between ~50 and 100 kPa” and I immediately had the visceral desire to throw them out of a moving car :D
English
@MiraiNoBeederu The explosive environment isn’t the only issue with a pure O2 atmosphere, even at partial pressure. If you’re exposed to pure O2 for extended periods of time, the lack of a “buffer gas” can cause pulmonary collapse (+ pure O2 at 40% pressure would still be highly flammable)
English
@teestar_writes It's also how the taumeoba survived in the book because there wasn't 70% nitrogen in the air like there would be on Earth. The oxygen environment at 40% pressure weighs less but also prevents the explosive, flammable environment that was a problem on Apollo 1.
English
@crysanaaru Also!
Weir: *conveniently makes hyper-advanced spaceship have an outdated internal atmosphere composition so he doesn’t have to address the fact that grace and rocky are transporting a star-saving amoeba that dies when exposed to nitrogen*
A fellow writer sees ALL lmao
English
@crysanaaru Which is an interesting choice actually, cuz modern spacecraft irl actually do have a much more earth-like atmosphere, including with nitrogen. So either Weir missed out on that detail or he was like “i don’t want anyone to think rocky just tossed a coin and settled on
English
I’m fully willing to believe she always had him in the back of her mind as an absolute last resort (cuz it’s literally canon), but to say she had some evil master plan to send him over the two other qualified astronauts who VOLUNTEERED WILLINGLY is asinine
tia ☆@thoschody
i'm not trusting anyone who says stratt always planned to send grace to space
English
@im_here_buddy Oh yeah? 😏
Did you know Earth’s global albedo in 2023 reached a record-low, and the most prominent negative anomalies were found over non-polar oceans, indicating a significantly-diminished cloud fraction in certain regions? (This was the basis of my Master’s thesis lol)
English
@teestar_writes You speaking science is Doing Things To Me
English
Assuming a SLP of ~100 kPa, diatomic oxygen would take up almost exactly 21% of the total air volume—therefore *pure oxygen* pressurization at 21.1 kPa in a confined space does provide a perfectly comfortable, breathable atmosphere. It was just oxygen in the tunnel. Nothing else.

English
@im_here_buddy Grace is lucky he met the smartest cookie in the universe cuz there certainly are some people out there that would look at an alien atmosphere and be like “well obviously the constituent with the highest concentration is the most important one” lmao
English
@im_here_buddy If it’s any consolation, Rocky was NOT dumb enough to assume a complex lifeform sustained itself on a chemically inert gas, and he also thought “let’s start with a constituent whose pressurization is *not* likely to kill the alien upon opening an airlock depressurized to 0-kPa”😌
English
@im_here_buddy Mad at first because of “inefficient alien biology design—why so squishy?!” and then just absolutely breaking down into a mournful little song because he killed the only friend he’s had in 46 years :(
English
Let’s learn atmospheric constituent ratios with mama fr 🤦♀️
English
@Maxxwel420 I’ll try to remember! ^^
And actually the fic/series this is a part of is already posted on ao3; this is just the final chapter I’ve been working on for way too long atp 😅
Here’s the series link if you want: archiveofourown.org/series/6155076
English
Ugh I can’t believe this chapter is still in wip status; it’s been three weeks—RELEASE ME!!! 😫😫
But on a real note y’all: how much do you hate Colt for saying this shit in a fight? Scale from 1 to 10 👀🤔
English
@Nope53701207 I can imagine Rocky’s “bossiness” makes him particularly prickly and grumpy, angry, stupid until he remembers Rocky’s not actually a man, and all of a sudden the switch flips and the bossiness becomes more endearing to Grace than irritating lmao
English
@Nope53701207 Lowkey, in my AU, he prolly woulda butted heads a bit with Yao too, especially confined in such a small space like that. The man has authority issues, and they’re very specifically MALE in nature 😂
English
Another fic snippet~
Grace returns to Earth and immediately cunts out at the guy who became Eva Stratt’s “successor” in leading the world’s rehabilitation efforts
