because he knows you have 10 seconds of useful consciousness after opening your helmet and wanted that fuckin thing out of his face, knowing it wouldn't take 10 seconds to take care of it
Just started watching this show. Pretty damn good.
Big fan of that Serenity ship they got. Looks just like a Homeworld gun corvette.
I tried to make it in space engineers but it didn't really work out so im going to try again (because I tried to build it in an atmosphere, forgot to save it, detached it --- and it promptly cratered into the ground because it didn't have enough thrust to stay airborne)
but one thing I've noticed is that "spaceship arranged like building" actually works really well as a design
You have 10 seconds of useful consciousness after being exposed to hard vacuum, no idea idea why uncle space bumpkin thought that was alright.
15 seconds, and its not a huge problem to momentarily expose yourself to the vacuum of space as long as you've exhaled before opening the suit. Plenty of time to pick your nose or what have you.
Watching through the first five episodes again, are the ships designed vertically?
If so, yes. I'm really liking the set/ship designs and how travel is depicted.
Yea, the direction of thrust is "Down" for all of the ones we've seen so far.
Awesome. I'm glad to see that. There aren't enough sci fi shows/movies with vertical deck plans.
The entire basis of the ship tech in The Expanse is that they can basically produce unlimited thrust; humans just turn into a fine paste if subjected to too many Gs, so their ships are ergonomically designed to travel at a comfortable 1G, allowing the crew and passengers to walk on the "floor." They also, however, are designed to work at zero G, and there are drugs and systems that allow them to go up to around 10G without killing people on-board, as long as they're in their crash couches.

So how do the space stations have gravity?
Centripetal force. IIRC Ceres is rotating enough to simulate .3G.

is this a thing we can do in real life. I was pretty sure the Belters had an evolutionary advantage regarding the vacuum in space and a normal person trying this would pretty much freeze their eyeballs solid or something

Belters don't have any evolutionary difference. They've only existed as a society for about 150 years.

huh
I think I'm reading to many sci-fi books these days
Nah, you'll die from the vacuum long before you get any serious freezing issues. Even with 15 seconds of somewhat useful consciousness it's an extremely bad idea. They put that scene in there to show what override said.

Thought it was a little longer than that and not sure about any. Anybody prone to claustrophobia probably ran screaming down into a gravity well as quick as they could. There is definitely some selection pressure on them but it is way too early for the kind of adaptions that Trace mentioned. Right now it'd basically be lower incident rates of things that are huge problems in that environment.

it is indeed a thing that was tested on Chimps in the 60s. Vacuum is also a really good insulator so you won't freeze in space, at least no in the time it would take to pick your nose.

Turns out zero conduction and convection is a pretty good way to not lose heat. Just leaves radiant which isn't very much at all.
Also why in spaceships your problem is just as often being too hot as it is freezing.
another fun fact is that if you get cut and start bleeding in zero g the blood collects in to a ball on the cut. It happened to the first space tourist who got a bit too carried away with flying around and smacked his head on a sharp corner.

god dammit I can sit here and explain the properties of quantum mechanics in a pretty thorough manner but holy shit I don't know the basics of a vacuum
You have 10 seconds of useful consciousness after being exposed to hard vacuum, no idea idea why uncle space bumpkin thought that was alright.
Why is it only 10 seconds? Is it because you're not supposed to hold your breath before being exposed to vacuum (because of pressure differences I imagine). Otherwise it seems like you would be able to remain conscious as long in space as you could underwater.
Capital is only the fruit of labor, and could never have existed if Labor had not first existed. Labor is superior to capital, and deserves much the higher consideration. - Lincoln

It's the same reason you need an air supply to climb particularly tall mountains: the amount of oxygen you need dissolved in your blood to not asphyxiate is higher than what is present (on mountains because the air pressure is too low, in space dramatically more so), and so nature does what it always does when there's a strong gradient of dissolved materials: the solute moves to the area of lesser concentration. So the oxygen is literally pulled out of your blood, into the vacuum inside your lungs, and out to the depths of space. Turns out in a hard vacuum, it takes about 14 seconds to pull enough oxygen out that you lose consciousness. This takes a little longer in places like on extremely high mountaintops or depressurized planes, but it gets there eventually.

you can hold your breath under water. Vacuum sucks the air out of your lungs and you are only left with the oxygen in your blood which gives you about 15 seconds before you pass out.
There is a wiki....but it's ridiculously easy to read too much and spoil yourself on events in future books...I am speaking from experience. I would also stay away from the the Wikipedia page about the books, Even the very general synopsis of the plot spoils later events.
Re the vaccum insulation discussion - there is a rather good bit on it in Charles Stross's atrocity archive. A group of commandos need to do a raid in what is basically a vaccum, they get fitted out with pressurised suits. The tech suiting them up explains to the main character that provided that he doesn't lie down on a cold surface (the ground) he runs a bigger chance of overheating in his suit than freezing to death.

Also worth noting, the reason you can't hold your breath is because the pressure differential will be serious damage to your lungs alveoli if you try to.
mass effect's codex has a bunch of stuff about how difficult dealing with heat is on warships that fire railguns (which generate a fuckload of heat)
because in space the only effective way to dump heat in a hurry is to make something hot and detach it from your ship
Dispersal of heat generated by onboard systems is a critical issue for a ship. If it cannot deal with heat, the crew may be cooked within the hull.
Radiation is the only way to shed heat in a vacuum. Civilian vessels utilize large, fragile radiator panels that are impossible to armor. Warships use Diffuse Radiator Arrays (DRA), ceramic strips along the exterior of the armored hull. These make the ship appear striped to thermographic sensors. Since the arrangement of the strips depends on the internal configuration of the ship, the patterns for each vessel are unique and striking. On older ships, the DRA strips could become red- or white-hot. Dubbed "tiger stripes" or "war paint" by humans, the glowing DRA had a psychological impact on pirates and irregular forces.
A ship engaged in combat can produce titanic amounts of heat from maneuvering burns and weapons fire. When fighting in a high heat environment, warships employ high-efficiency "droplet" heat sinks.
In a droplet system, tanks of liquid sodium or lithium absorb heat within the ship. The liquid is vented from spray nozzles near the bow as a thin sheet of millions of micrometer-scale droplets. The droplets are caught at the stern and recycled into the system. A droplet system can sink 10-100 times as much heat as DRA strips.
Earth has a huge population, and most of the population live on "basic", ie basic income from the government, and mostly party their lives away. The people that work, do so because they're competent and want to work. Earth is very rich in resources and manufacturing, meaning the UN can support that many people on basic.
The Martians, on the other hand, are a people with a goal: they want to make Mars green. They have nowhere near the same population as Earth, but they have a technological advantage and a more advanced navy than the UN. The Epstein drive was a Martian invention and gave them the upper hand, allowing for massive sustained acceleration. When Mars declared their independence from Earth, sharing the Epstein tech was what prevented all-out war -- and it was far from certain that Earth would have won it.
I'll just quote the wiki:
Many of the colonists of that period wanted to secede from the rule of Earth, and compared their plight to that of North America in the 1500's (Mars was a two month journey from Earth using the drive technology they had at the time). Two major events almost led the two planets to war, the first happened when a group of secessionists published their manifesto, leading the UN to invoke the 'breakaway province rule' and launch forty ships towards Mars. Negotiations behind the eventually cooled things down, and the ships turned around and headed back to Earth.
The other major incident came when the United Nations issued a statement that all future Martian ships would be contracted through the Bush orbital shipyards on Luna. The Martian government didn't even reply to that request and work at the shipyard continued. The UN then ordered that all shipyards on Mars shut down until an inspection team could be sent out there, but it would take them seven months to get a team together, and another six to make the journey to Mars (due to the planets position at the time). Once again, this request was ignored. Rumors of war started up once again, and if not for Solomon Epstein and his accidental invention of what would come to be called the Epstein Drive, war between the planet and it's colony may have been inevitable.
After Solomon invented the Epstein Drive (and lost his life on the initial test flight, due to the unprecedented power), Mars had a major technological advantage above Earth. The new ships could go further and faster than anything that had been built before, while using significantly less fuel, opening up the rest of the solar system for exploration and settlement. The colonial Martian government reached out to the UN and offered them access to the Epstein Drive in exchange for granting Mars its sovereignty.
Then you have the Belt and the outer planets -- and the Outer Planet Alliance, OPA.
The Outer Planets Alliance, abbreviated OPA, is an organization that started its life as a labor union or advocacy group, fighting for the interests of inhabitants of the Belt, often in direct conflict with the inner planets' Earth Mars Coalition Navy. Its logo is a split circle and headquarters is located on Tycho Station.
The OPA is described as either a social movement, according to people sympathizing with Belters, or a terrorist network, according to the inner planets.
OPA is more of a gathering of various factions for a common goal... most of the time. The biggest faction is led by Fred Johnson, the Butcher of Anderson Station, an ex-UN soldier.
beat me to it...yeah, 3 major factions. Mars, UN (Earth), and the Belters/OPA Mars and Earth are the superpowers and don't really like each other. Mars has surpassed Earth in technology and they have the coolest military toys. But both Earth and Mars treat the Belt/OPA like red-headed step children. The Mormons are working with the OPA to build the biggest starship in history, a generational starship meant to travel to another star over hundreds of years.

One additional note: Earth is actually resource-poor in one critical element in the books: Lithium. Lithium is required for Tritium/Deuterium fusion (you bombard it with neutrons to produce Tritium), and it's been 150-200 years since fusion power was developed. With the additional strain from an enlarged population, shipbuilding, etc, all the "easy" Lithium sources have been just about mined out on Earth. Mars and the Belt still have very rich lithium reserves, which was why Earth was so economically invested in Mars to even want to prosecute a war across such a vast distance.
