I see a lot of debate on here about what happens when characters open fully pressurized airlocks, which happens a few times I think in the books/show. The prevailing opinion I see on here is that there isn't enough air in the airlock, and you would just feel a 'gentle breeze through your hair', and on the other hand in some sci-fi people are shown getting ejected out at high speeds with their eyeballs popping out.

I did some basic math to try to get a feel for it, feel free to correct me.

I assume:

• Airlock overall pressure difference of 1 atmosphere ΔP ~ 10^(5) Pascals
• Airlock width L = 2m (~6 ft.)
• Human width Δx ~ 0.2 m (~8 in.)
• Big assumption: linear pressure difference across the airlock from vaccum to interior wall. A pressure wave or shock would probably increase the difference you feel.
• Human one-sided surface area of A ~ 1 m^2
• human mass of m= 100 kg

The pressure difference over your body is then:

δP = Δx/L ΔP = 10^(4) Pa

δF = A δP = 10^(4) Newtons

This implies a gravitational acceleration on a 100kg big boy of

a = δF/m = 10^(2) m/s^(2) ~ 10 g's

In other words, this estimate would have you blown out of the airlock at 10 times the acceleration of gravity, about the maximum acceleration an expert trained human can sustain without injury.

No idea how long this would last though, it would probably be over pretty quick. If it lasts 1 second which seems long, then your final speed would be 100 m/s ~ 200 mph, which also seems a bit fast!

EDIT: u/Jakebsorensen mentioned the drag force so I estimated it as well.

Drag force F=1/2 ρ v^(2) C_D A, for:

• drag coefficient C_D ~ 1 for a human
• ρ = 1 kg/m^(3) for air
• No idea for velocity. For a huge range, take 10% to 100% of the thermal velocity, or v~(46 - 460) m/s
• Again, A ~ 1m ^(2)

This gives F ~ (10^(3) - 10^(5)) N, or a ~ (1-100) g's. Obviously a huge range because it goes as the square of velocity and I don't really know that number.

Just got the audiobook version of Memory's legion (after having read books 1-9). WOW I was not expecting to be so emotional over the very first novella in the book. The way that, in his final moments, Epstein has to let it sink in that he'll never get to see the outcome of his discovery, the impact that it has on the future of Mars and Earth humanity's path to the future. And that he never got to say goodbye to Caitlyn. And Caitlyn, who will have to think of her husband sailing away from her into the void at an unreachable rate, and who will be reminded of this at every mention of this new incredible Epstein drive technology. It's devastating. There's so much more to say about just this one novella, I cannot wait to read the rest

Hey Expanse Reddit!
I'm working on a cosplay for Tiamat's Wrath Timmy and in the process of said cosplay I'm making a medkit for his cave; my original plan was to bid on Laconian Medkit auction but got outbit in the last 10 minutes. Sob story aside: I am coming to y'all with a request for help with remaking the prop instead.
From what I can tell: production staff used a modified fishing tackle box that appears to be around 12in long and just a little bit taller.
If anyone can help me track down the base item production used for this prop or something similar to it I would be very grateful

I don't think I've seen space battles anywhere near as awesome as in this show. Full of tension, drama, and danger. Really exciting stuff. Somehow looks completely grounded despite being fantasy futuristic technology. I recently learned the series was cancelled, which is why there were only 6 episodes. I would have like to learned what was up with protomotocule looking space ship above Laconia I think it was called, as well as those probably protomotocule based "dogs" that brought the kid back to "life".

Regardless, I think I've found a book series to look for next time I want to read something.

Hey everyone, so I’m reading through Tiamat’s wrath at the moment (rereading, so spoilers are fine for me but maybe not others) and was wondering if they ever explain why that system was set up the way it was? Was it supposed to be a trap for the goths, like a system-wide land mine? Or was it spread out and empty because of how much gravity is pulling on everything with a neutron star being so close?

When the proto molecule hybrid is aboard the Roci, they go into zero G to distract the hybrid and buy time. Holden tries to grab his gun, which is floating just out of his reach, which causes the hybrid to climb the ladder and approach Holden.

But, why was the hybrid just walking around when there was no thrust gravity. Is this a mistake, or was it ever explained?

We don't hear about this station in any of the previous episodes, and then suddenly, out of absolutely nowhere, in Season 2 Episode 2 Holden uncorks knowledge of a super-secret station on which Errinwright's entire plan hinges. How did this happen? Why did the show not explain this?

P.S. No spoilers, please. I'm on Season 2 Episode 5 right now.

I'm not quite understanding this problem she's having in season 4. So because she grew up on the belt where there's less gravity, going to a planet like earth and illis crushes/compresses her body? Then why are all the belters that set up shop on Illis completely fine? Won't this make the "gold rush" for the 1300 planets impossible for belters? Sorry if this has been asked a lot or it's fairly obvious

Hi everyone!
Hope you’re having a great day!😊 I’m aware the audiobooks have been discussed. When I look on Audible, Leviathan Wakes is $35! Is there anywhere else I can download it for less? Or perhaps even free🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️🧜🏻‍♀️🧜🏻‍♀️🧜🏻‍♀️💜 Thanks for any help. I have looked online but thought this group might know better. 😉 Thanks again

I'm rereading the series, and am mostly done with Babylons ashes. Nemesis games introduces some of the most questionable actions for Holden and Naomi that always make me think, especially as regards Naomi's abandonment of Philip. Naomi has a point that she had the right to walk away, and that she couldn't get back to him after he was kidnapped by Marco, but the novel focuses primarily on Naomi justifying this decision to herself and to Holden. The conflict that I feel is missing here is Naomi justifying it to Amos.

Amos was essentially raised as a sex slave and then groomed as a violent criminal. It's pretty clear that this is the worst childhood you can imagine. He's willing to wade through oceans of blood to help people like praxidike mung and Mei because to him, childhood innocence is the one cause he doesn't need an externalized moral compass to work towards. Why is it, then, that when Naomi leaves her son in the custody of the kind of person who groomed amos to be a murderer, that amos just accepts it?

Even if she was right to leave when she did, by the time nemesis games takes place, Naomi had had tons of opportunities to tell the heavily armed crew of her martian gunship "hey guys, favor time - can we go get my son from the maniac who kidnapped him? Naomi seems like the person he trusts the most, and I have a hard time believing he wouldn't view this as a betrayal.

On book 4 now, really enjoying it, he has good tone and pace, and enough variety between the characters. Watching the show probably helps me differentiate everyone as well, we'll see how i fare after book 6.

But! Every single time Avasarala speaks, all I'm thinking is "That's not my Chrisjen!". Shohreh simply "ruined" the most fun character for me.

I been reading Wheel of time for a while now and been hanging out on WoT Reddit and noticed that it is extremely common to re-read that series multiple times. There is even people who read it 10+ times.

Is this also common for this series?

You guys are pumping me up to re-read this again!

The Expanse is probably the best scifi series of the 21st century thus far. The world building has been phenomenal. However the one faction that gets the least amount of screen time is Mars. Yes we get to see the perspective of the MMC/MCRN, but that is fairly limited compared to Earth and the Belt where we not only have major characters in their respective militaries, but we also see political leaders. I’ve seen people suggest that Mars is some sort of military dictatorship, but I think that that misconception comes from the fact that we never see the Martian government.

As per title, how do you manage to watch the TV after reading the books, or the other way round, since you basically know how the story will unfold?

I am approaching the end of Cibola Burn and these motherfuckers are vile except for maybe the scientists and half of Havelock.

"Oh Adolf Murtler said so do we now going to kill everyone not posing any threat to us anymore"

These pieces of shit deserved to be bombed, and not as collateral. Either vile to the maximum or so spineless they insist on following evil orders without ever questioning it.

Plus they come in and claim all of other people's labour from the start. Fuck them.

Update: Reaching the aftermath the company itself was nice even to the ones not loyal to the security team.

I hate Murtry is more accurate. And the Chief Engineer.

Read Leviathan Wakes and now watching first season of The Expanse and - with all due respect to the actor who is playing him - cannot understand the casting choice for Holden. Not even remotely what I was imagining. The actor is too young for one thing, Holden should be a bit older than the rest of the crew. I expected a John Corbett or Josh Lucas type, brash, physical, slightly grizzled and cynical but with sense of humor. It’s off putting to the point that I don’t know if I’ll keep watching. Steven Strait isn’t a bad actor, just so far from the Holden I was envisioning. Maybe they wanted someone who strongly contrasted with Thomas Jane? Did I misread or did they really go off the page here?

EDIT - Thank you for the discussion everyone! I posted this right before I went to sleep last night and forgot about it until I saw 50 emails from reddit this morning. Also should clarify I listened to the book (20 hours!), I didn't eyeball read it so I definitely missed some of the descriptors of the characters, or didn't take it in, especially Holden's age. I was imagining everyone older than they are written. You guys also reminded me how frustrating Holden's character is in the book. It was nice to have people to vent my feelings about this to as no one else I know is reading or watching this series.

One of the things I appreciate about this show, compared to other space shows, is the realism and lack of fillers. No" lets just focus on the crew and let them have fun or a groundhog type day.

I'm reading Leviathan Falls firbthe first time and there's a part where the Roci is burning away from the Laconians.

"The physical stress and the fear were as familiar as an old, often sung song. A hymn to the price of violence."

Damn- that hit hard.

What are some of your favorite passages?

MIA yesterday AND today? What is going on?

Was a huge fan of the tv show. Finally started reading the books about a year ago and I’m just about finished with Caliban’s War. It’s crazy the amount of foreshadowing that’s disguised as odd little character moments. Some big examples I encountered in the last few chapters;

• Holden is standing on the hull of the Rocinante patching holes from the Mars/UN Battle when he starts staring out at the stars and musing aloud to Naomi about how all those stars mean billions of habitable worlds. He jokes that maybe someday their grandkids will see them, which Naomi thinks is just absurd.
• They even go on to talk about how much humans are just like the builders of the protomolecule, seeking out every corner of habitable space in the galaxy.
• And like a chapter later Avasarala has a conversation about throwing fake asteroids at the earth!

I feel like the Leo meme pointing at my book every other chapter. This series is so rewarding no matter how you enjoy it.

... is the real Miller speaking to him? It could just be the protomolecule further manipulating him

I started a few days ago and I'm already on Season 2 episode 7. I love Sci-Fi and while I like the mystical types of sci-fi, I'm starting to realize that I like the "hard science" type of sci-fi maybe a bit more. The show For All Kind is very similar to this show and I love it but I also love the show Foundation.

I have never laughed so hard as I have listening to Avasarala’s dialogue. Like, snort laugh (loudly) at her responses to Errinwright et al.

Discuss.

Last maybe 20 minutes of the last episode in season 5 completely shifted the cinematography into a full on movie format.

Absolutely 100% chance they were going to do a movie next instead of the season 6 we got. It was set up nice too and would have been an interesting transition I don't know has ever been done before.
