This won't happen. It's far more viable to fly planes. The noise would also be dreadful for whales etc.

If an astronaut's suit would jettison in pieces, exposing him suddenly to the environment of 92 atm, loss of consciousness would occur in few seconds due to the blunt trauma of the soft tissues containing gas and pressure effects on the gases dissolved in water. Atmosphere would ram the tissues into the lungs and the abdomen cavity would partially collapse. Eardrums would collapse. Severe internal bleeding would occur. The rest would structurally resist because there's no free gas. Hair curls up, melts and chars in the first moments, too. Eyes would coagulate quite fast and ooze out. Consciousness would not be lost immediatelly and suddenly. There'd be considerable suffering. The temperature of the atmosphere is very high, but it's supercritical fluid of a molecular compound and not a solid touching the body. Heat transfer is slower, so it wouldn't be like dipping into molten zinc. The fact is that our body is around 60% free water and 4.181 kJ/kg°C for water is a lot. Sudden exposure to 92 atm is a lot more serious thing. However, surface charring is a possibility in few minutes. After loss of consciousness, heart would go into fibrillation during the next few seconds because of loss of blood and increasing heat effects. Soon after, the heart stops working completely as the proteins start to coagulate above 45°C. Brain death probably in the first minute. Random neuron firings would slowly stop in the next few minutes as the temperature of the brain increases. Now comes the "cool" part. Interstitial fluid and plasma begin to boil a bit above 100°C at 1 atm. On Venus, it would boil at some 300°C. This probably means that tissues would lose their elasticity (100°C and 1 atm, the body swells like a sausage in a microwave and then bursts, releasing steam) as it is thoroughly cooked. Heat crawls inside towards the body core. Water can't boil, but it can cook the tissue. A bit above 200°C, fat starts to degrade, creating smoke. After 300°C is reached, boiling begins. Probably in the next 30 minutes or so. It could be calculated, but the values would be quite rough. Tissue flops and oozes from the skeleton, releasing steam and smoke. It would be a gruesome sight. Volatiles inside the skull would seep through eye sockets, ear canal and probably the great foramen of the brain. Long bones such as femur could crack suddenly, releasing volatiles. As water is slowly going away, smoking becomes more apparent. Tissues lose their compound water, too. Acrylamide is released. Maillard reactions give way to charring. First few centimetres of the body would be charred in an hour, maybe less. I'd say the complete carbonization throughout the body would take at least one whole day. So... yeah. You don't want that.

Pawelk198604, how about "Is 3.5 G a lot"? You're using the Internet which is mostly in English language. Have you ever seen a phrase "does x is big"? Come on, it's not so hard. No, 3.5 is not a lot, that's a standard peak acceleration in common rollercoasters, drop towers and other gravity rides. Some go a bit over 4 G, but those are shortlasting peaks. It's scary if it's your first time, but when you learn how to control your guts and breathing, it's great fun.

Nice doggy...

Yeah, that happens when the fuel is cheaper than a bottle of soda. I thought I was going to enjoy this video, but it kind of disgusted me. Cherry on top was screaming of rednecks at the end.

Yes, it's a fact. Planetary bodies of all kinds are charged and differ by the amount of charge on them. It's simply something that must happen when you've got vacuum and a source of electrically charged particles emanating from a star. No, that's a completely separate problem. Huge charge differences can cause a breakup of the insulator. High voltage power lines are alternate current based, and such current can flow through insulators.

I must apologize, I've read it wrong. Exposure? Of course there'll be exposure. Every piece of fish you eat, every breath you take, there'll always be exposure to Hg. The greatest exposure by fillings is, correctly, during and after the procedure, while the filling cures. The drop in exposure is exponential and after few days negligible, even with subsequent years of gradual, albeit very weak, wear of the material. Wear is very weak if the doctor has shaped it correctly. New composites are a better choice, but it's not like amalgams were dreadful. Coal power plants and sea food were, and still are, the most plentiful sources of this element.

I doubt you can prove that. Basically everyone in the 20th century had such filling. What are your sources to back up such claims? Exposure exists, but death? No evidence.

It's a great show, I agree.

That is a lie. Please don't use anime for spreading web-paranoia about fillings. Fillings won't hurt you because the metal is sealed in alloy matrix. You get more mercury by eating fish. If you need to put a new filling, new composites are a better choice, but removing old, functioning ones is a huge mistake. That would be compromising the sterile insides of the tooth (which mostly doesn't end well) and the drilling and scraping of the filling releases lots of mercury.

I've heard a reporter saying . So stupid, so, so stupid.

Earth's SOI isn't a sphere. It's an uneven spheroid, and fluctuates due to the Moon and the Sun. One would have to search for the highest longterm stable orbit.

I think some of you here never actually had influenza. Bad cold is not influenza. I had H1N1 and a "regular" influenza in my life. You don't want either of them. It will chain you to bed and if you have chronic diseases or you're old, it can easily kill you by itself or secondary infections. H1N1 turned my runny nose into a bloody nose and made me nearly incapacitated for a few days. Since H1N1, I get vaccinated every year.

So, religious freedom is above the right to health and, in some cases, life? Screw that. It's neither morally correct or existing in laws. That's why if there are two fanatical Jehowah's witness parents who don't allow their kid to get a dose of blood even if the alternative is death, the state stomps their "religious freedom" over because it doesn't matter. I do the same thing. I buy the thing and ask my nurse to give it to me, because I don't want to help the virus to spread around. I don't want to be one of the pods in which it will mutate, either.

Which "rare diseases" have "we stopped vaccinating against"?

[Word we'd rather people didn't say on our forum] who don't allow their kids to be vaccinated are endangering their lives. Compulsory vaccination is beneficial and therefore part of the law where I live. Vaccinating yourself lowers the chance of getting a disease and the chance of infecting others. It does not remove the possiblity. It just drastically lowers the chance. If there's enough immunized people, the disease can't spread around. Herd immunity. Immunology 101. Turn vaccination into voluntary and you get outbursts of polio and other diseases. People who can't get a vaccine because of allergy get the disease, too. This has started happening more than a decade ago when stupid people started listening to that quack doctor who fabricated the whole autism-vaccination connection. He has lost his licence, thankfully, but his horrific legacy remains. Its death toll will be scary.

No, it's perfectly objective. Russian media is full of crap. It's a remnant of the Soviet propaganda system. They fabricate a lot of stuff which are then spread around by other news outlets. You might think USA media is horrific, but it's nothing compared to Russia.

As I've predicted. http://news.discovery.com/space/private-spaceflight/sea-plankton-on-space-station-russian-official-claims-140821.htm "Russian source" - never trust that. Never.

So what's exactly the question? Or you're just informing us about your oral condition?

Why do you people think the average viewer of TheFineBros channel is a moron? Also, if not Teens React, why not Elders React?

Whatever it is, it's caused by humans. My concern is about the actual validity of these news. We're discussing something mentioned by some Russian guy. There have been tons of such looney notions in the last decade, all coming from "some Russian guy". If there really is contamination, it's not living. Those must be spores which were found viable (in some low percentage) after put inside. Plankton means organisms that live in water, but can not swim against water currents. Nekton are organisms which can swim against currents, neuston are the ones living on the water surface (gliders), benthos are the ones living on the bottom of the water body, and pleuston lives in the liquid-gas interface. Krill belongs to plankton. Just wanted to make things clear.

Saying that "air currents" reach ISS is preposterous. I can't believe anyone is actually considering that as a possibility. It probably speaks volumes of the stupidity of the Russian academia, something so painfully obvious in the last two decades. I don't see the big deal here. It's contamination that probably came to ISS by stuff launched from Guiana Space Centre which is very close to Atlantic ocean. I'm sure various stupid pages will now blow this out of the proportion, so that this: "Results of the scope of scientific experiments which had been conducted for a quite long time were summed up in the previous year, confirming that some organisms can live on the surface of the International Space Station (ISS) for years amid factors of a space flight, such as zero gravity, temperature conditions and hard cosmic radiation. Several surveys proved that these organisms can even develop." will become: "There's throbbing goo in space!" No organism can live in space. It can hibernate, and that's not living. It's suspended metabolism. Nothing happens inside the cell, but everything is set up to kick back to work after appropriate conditions are met (pressure, water, heat). Some single cell organisms have the capability to turn into spores which are very resilient to vacuum and low levels of ionizing radiation.

gpisic, nobody is trolling you. They're just making you get a taste of your own medicine. The mesa on Mars is not a face. It's a mesa. There are tons of similar stuff and it's called pareidolia. Human brains have evolved to recognize patterns. Sometimes it's useful, sometimes isn't. This is one of the examples where brain played a trick on people. Why are you acting irrational? You've been presented with a high resolution photo and a radar scan, yet you claim NASA "photoshopped" it. That makes you the same as Apollo landing conspiracy nuts which, when presented with proof, either deny it or ignore it and jump to something else. Some examples of pareidolia. And here is a high resolution photo of various heart-like whatzits on Mars.

So... what?

Sorry, but... (I'm talking as an astrophysicist kind of guy.) Here's a video to cheer you up.
