I'm watching the live screening of Peter Pan with my mom, and I'm trying to find Neverland in SE.

I figured I'd go back to October 11, 1907, when the book was published. I'm in England, just before dawn, so I can go "straight on till morning." Fat lot of help those directions are dry

Every time I think I've found it, it's just Venus or Jupiter. Does anyone have any ideas? wacko





Careful. The PLATT Collective has spurs.

Maybe it's underneath Europa's ice?




I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

Just watched The Hobbit: Battle of Five Armies. I liked it much more than Desolation of Smaug, maybe even more than An Unexpected Journey. smile

SPOILER ALERT



Has anyone else watched the movie yet here?

lets start Discussion: what will kill you first on venus, the heat or the pressure?
smile have fun discussion

spacer, If you're going to fall down from the top cloud level (50km, where the normal pressure is present), the answer is hot sulfuric acid.

The heat would kill you first, the human body is capable of withstanding very high pressures.

But long enough to keep you alive until you die from the heat? I believe that humans would survive a couple of minutes in the temperature of 400 C.





Love SpaceEngine!

My guess would be that the pressure would knock you unconscious instantly, and then it's would be hard to tell whether you die of the sudden pressure increase, suffocation or heat since all would be fatal. It's kind of like asking if you're shot, stabbed and thrown into a fire, did the shot, stab or heat kill you?

But it's interesting to think that between 50 and 60 km up you would experience pressure and temperatures (and well as gravity) like on Earth, and you would probably be ok in an airship for quite a while with just a full reasonably tight face mask and oxygen and normal clothes.

There's still a lot of acid clouds around this location, you'd better not allow any contact with your organic, hm, parts, so care to use pressurised suit.

From what I understand, there are no places on Venus where temperature and pressure are both Earth-like. At altitudes with Earth-like pressure, the temperature is too hot, and at altitudes with Earth-like temperature, the pressure is too low.

i think that the pressure will kill you first because i think that humans can survived in 400C for few sec or 0.00001 sec?
but the pressure just crash your body Immediately

The Veneran atmosphere consists of 150 ppm sulfur dioxide (maybe varies with weather and altitude), which is around the limit for what's lethal for humans even just for short exposure, but I don't think 150 ppm will easily burn your skin.

I would consider temperatures from -50C to +45C and pressure from 580 hPa to 1060 hPa Earth-like (in the sense that many people live in places comfortably where such conditions are frequently experienced). A pressure well over 1060 hPa wouldn't be a problem, though. According to the Wikipedia article, you would get roughly 34C and 640 hPa at 54 km altitude.

Venusian atmospheric temperature profile
Pressure profile

Venus has an altitude where pressure and temperature are comparable to Earth's surface, but it is below the cloud tops. So sulfuric acid would be an issue.

Venusian surface temperature: ~740K
Surface pressure: 90atm (~91 bar)

Which of these kills you first? Depends. How do you get there?

If "teleported instantly", then the pressure does. Not because it crushes you. 90atm isn't that much -- it's comparable to being about 900m below the ocean surface. Human body can manage this without much issue. The problem of humans in hyperbaric environments is not the compression, but the gas toxicity.

But humans are rarely subjected to those pressures instantly. So if "teleported instantly", then it's a different effect that is important to your demise: the shockwave (over 1000psi!) ripping through your throat, sinuses, and lungs. Think the reverse of explosive decompression.

Otherwise, the temperature gets you first, before any other effects of high pressure. 740K is very hot, producing 3rd degree burns in less than a second, and carbonizing vital tissues shortly thereafter.
