Your blood would never boil at low pressure, even in a vacuum. In fact, there's a space suit in the works that is more of a skin-tight latex suit that is supposed to prevent swelling. It's called a "Space Activity Suit". You'd swell up and wouldn't be capable of moving, but your blood wouldn't boil because the veins and arteries in your body are elastic and wouldn't let it experience enough of a pressure drop to boil. I'd be more worried about ocular damage and hypoxia than boiling blood.

[QUOTE=Awesomecaek;36128234]It would "boil" and your organs would swell, but nothing would visually rupture out of very special conditions.
You would go swollen, then stiff, and after few days, freeze into a chunk of ice. That's all. No "HRRKKKK *poof*" nor "shhhhhsssss *I turned into icicle in two seconds*"[/QUOTE]

[QUOTE=AceTub;36128180]Free fall at the speed of sound? What ever happened to terminal velocity?[/QUOTE]
The atmosphere is thinner the higher you go. So at the height he's jumping at, there's very little air to slow him down. Less air resistance means higher terminal velocity. You achieve terminal velocity when the downward force of gravity is cancelled out by the upward force of drag (air resist.).
It would suck if he burned up.
[QUOTE=download;36127906]I would so jump this if I was given the chance[/QUOTE]
Why does this have so many disagrees?! I mean, you only live once. You'd be stupid to say no if offered the opportunity!
It's not like these things are too dangerous anymore, either. Modern technology has seen to it that things like parachutes are made to be stronger now than ever before - the chances of some failure occurring that will result in your death are pretty low.
I'd definitely do a jump like this if offered the chance.
It says he will break the speed of sound. How is that even possible? Humans have a terminal velocity.
Wait durr, less resistance higher up in the atmosphere.
I respect the guy for doing this, I'd be scared shitless at that height :v:
Gotta go fast.

[quote=]Though your chances of surviving such an experience are slim, your body would not explode (although see below). In fact, if you were able to scramble to safety quickly enough (as the helmetless astronaut did in the famous scene from 2001: A Space Odyssey), you might emerge virtually unscathed.
It's true that in the absence of ambient pressure your blood and other bodily fluids would boil, [b]in the sense that they would turn to vapor. But that's not as drastic as it sounds. Your soft tissues would swell markedly, but they'd return to normal if you were recompressed within a short time.[/b][/quote]
If you're gonna quote something, don't leave important parts out, thanks.
Boiling doesn't necessarily mean that the blood would heat up to a boil.
Do record pls.

Yeah, but it's really annoying when people say these things and it's said in such a way that, if you read between the lines, it' obvious they're trying to imply it 'boils' in the same way that the water in your kettle boils when in reality that's not happening at all. No energy is liberated in the process, and conversely no energy is required to make certain liquids boil when the ambient pressure is dropped.
At 1 atmosphere of pressure everything has 101325 Newtons per square metre of pressure put on it. Just looking at that force alone for a second, and ignoring the fact that it's actually exerted over an area, that's still about 5.5 times the average force exerted on a baseball when it's struck with a bat, and 101325 Newtons works out to be also about 1/123 times the thrust of a space shuttle on lift off (which may not sound like a lot, but... holy fuck, have you seen a space shuttle take off? 1/123 of that is still a LOT). Those equivalent forces spread over a square meter are still a lot - it's amazing that everything's not just totally crushed under the atmosphere when you think about it in those terms.
Remove all of that force, or all of that force per unit area, and all of a sudden a lot of molecules don't really have the incentive to stay bound in a liquid state anymore, so they... well... don't. They just come apart and become gaseous. But there's no heat evolved, you don't 'boil' alive or anything like that.

[QUOTE=Awesomecaek;36130125]Insisting on semantics which mislead most of the audience hurts the informative value.[/QUOTE] So what they [i]should[/i] do is explain exactly what happens and what it's called. I'm not defending the article here.
It's like saying "If you fell down into sun, you wouldn't burn, period."
That's true, because there's no oxidizer in sun and it would just evaporate you and turn you into plasma, but the result in the common sense of "burning" is pretty much the same.

There's just no point in mentioning boiling, in case of the article, then.
Just say "if something goes wrong he will suffocate", because that's true. If somebody is interested into the details of his demise, not as important as suffocation, he can look it up.

Its called a fear of heights
[QUOTE=Matrix374;36130446]Its called a fear of heights[/QUOTE]
I think everyone is scared of heights when it comes down to it. If you're not then there's some misconnection in your wiring, because it's a part of self-preservation to be scared of things that can, y'know, kill you.
That said, as scary as such a thing might be, it'd also be exhilarating. As long as you trust that modern day manufacturing and testing techniques are good enough to essentially minimise your risk of death to near zero by producing high-quality, tested products (which in the case of parachutes they have to be or... lawsuit!), you should be able to push the fear aside and seize the opportunity.
Also Newtonian mechanics and other classical physics is understood pretty well, so the chances of somebody fucking up and you burning up in the atmosphere because somebody forgot to do the calculations are pretty low.

[QUOTE=DainBramageStudios;36130799]physics does not work that way[/QUOTE]
Oh, that's why I got all of those dumb ratings. You guys do know it's possible to decelerate, right? I'm talking about something like what Orbital Outfitters is trying to do. Make a suit with the proper thrusters on it to jump out of an orbiting spacecraft, stabilize you if you're wildly spinning, do a retrograde burn to slow you, then fall the however many miles to the surface safely. I'm saying that a jump like that would be truly impressive, unlike this, which is just jumping from increasingly high-up balloons.
