The Human Body in Spaaaaace Quiz

[JoeSchmuckatelli]

I originally plunked this down in the catchall - but I think it deserves its own thread.

(Mods - feel free to eliminate if you disagree) 

The above is a quiz to see how well you understand what happens to humans in space.  We get these questions from time to time - so why not it's own thread? 

Also-report your score!  I got 6 of 10... Clearly a duffer.  =/

#1 is wrong.
It's about 15 seconds of "reserve time" before getting unconscious in vacuum, and about 1 minute till death.

Also ABC are perpendicular to D. They can jump from ship to ship,, but if stay longer, they will A,B,C.

Also the body can't stay intact because the hands start swelling at 12+ km.

#2 is wrong.
There is a gadget.

As they live in space, it should be there in any case.

#3 is stupid.
Is a carriage for the paralyzed patients a proper prop?

#4 is both wrong and stupid.
a) They can't raise in zero-g.
b) Mammals breathe thanks to bones. Without them the breathing muscles would have no basement.

#5 is stupid and overoptimistic.
This station is rotating as a solid body, it can't just stop.
Also on a sudden stop a half of passengers would not just liquid.

#6 is wrong and irrelevant.
All body blood is on top in zero-g.
Too many advisors around.
NASA may say what they want, a couple made an experiment in a vomit comet, and the answer is yes but why, also requires an equipment.

#7 is incomplete.
They also vomit.

#8 and #9 are added by a genius,

CNN is such CNN...

Upd.
What do you say now, silly CNN?

UPD 2
They have carpets on ISS!!!
Look at the background.

5 out of 9. And I concur with @kerbiloid on all points.

[tater]

I stopped taking it, then came here to write a complaint about the test, but @kerbiloid already did it for me.

I should have known since it’s CNN that the chances of it not being entirely wrong approach zero.

[JoeSchmuckatelli]

Lolz. 

Clearly I brought it to the right place!

Remember the Gell-Mann amnesia effect.

You realize the reporter that wrote that has literally no idea what they are talking about, then read the next story about literally anything else, and you believe it, not internalizing the fact that the next reporter is equally clueless.

Sadly this results in societal madness.

1) yes but you are unlikely to do much work during the 15 seconds, now the one watching you doing maintance on suits then the outer door open probably do an override close and an emergency pressurizing and you live 

2) makes sense, more an issue if you get an running nose during eva, good gas masks has an drinking tube guess space helmets has to. 

3.4 is stupid, yes astronauts staying an long time on IIS or MIR are weak getting back to earth. But raising humans in zero g will not work well. 
Now down the line you will likely get people spending years in low gravity and not exercising and will get in serious problems returning to earth. 
No bones however will not work as you can not push for one. 

5) yes how does this happen, and if say you had an rotating segment on an large structure who is not rotating the joint will be your main problem. 

6) equipment like something to hold on to yes. More experiments are needed. 

And yes its CNN.

Jump, open the hatch by an emergency handle, pull by hands to push the body in, fall, hope that either the airlock will close the door automatically, or there is another crewman inside, to let you breath in 30 seconds before the death happens.

So, a clever airlock is much more important than a "clever home".

Irl they pray meditate have a rest in a decompression chamber with low-nitrogen atmosphere for almost a day before EVA, to let the dissolved nitrogen escape from the blood.

See Quest, "camp-out".

So, if they have snots, they should stay inside, if no - the pressure-caused nausea will happen before the EVA.

Unlikely they would even survive.

Bones just exist. They will get fragile, but still enough for breath muscles. Without the chest bones a human can't breath.

They brought the particular station, it doesn't have a rotating segment.

It was described as a special (blanket or coat) with latches, to wrap around and fix together inside. The (married) testers were from the dedicated videoindustry.

(So, the s01e01 Expanse scene is not very scientific.)

I saw "CNN" and said 'nope'. Not going to give them the clicks.

Best,

A lot of these are worded poorly enough to be either ambiguous or just wrong. It's pretty clear that the author took some interviews not meant for purpose of creating this quiz and created the quiz without letting anyone proof-read it for accuracy.
