Let's say 44% Argon, 22% Oxygen, 22% Neon, 11% Helium, and 1% Nitrogen, CO2, etc. at 1 bar.

would these gases filter out of our bodies fine? Or would we all get the bends?

I'm talking about if the whole atmosphere changed, not like scuba divers or anything.

Thank you...

I am a nerd myself and I'm asking this on curiousity... please try to answer at least one of these :)

If you have 1 cubic km of atmospheric gas (78% Nitrogen, 21% Oxygen, 1% Argon) at 0.8 bar, by what percent/ value must the volume of the cube be reduced by to make the gas 1 bar?

What would happen to a helium balloon in microgravity (like a space station). Would it just levitate in place or would it compress first?

Sorry I can't grasp some scientific concepts, but i'm really interested! Thank you :)

If you pumped different gases into different areas of an airless space module, until reaching the necessary amount to reach 1 bar, would the gases mix or stay seperate?

What would happen to a helium balloon in microgravity (would it just levitate in place or would it compress first?)

Does it take less gas to fill up an equal volume room ( to 1 bar) on Earth than in a space station (as air would be weightless in space so less pressure)?

Sorry I'm a teenager, and can't grasp a lot of scientific concepts yet, but i'm really interested! Thank you :)

Last night I slept at about 12:45 am (don't ask), and was laying in bed ready to sleep.

Suddenly I was wisked away from my comfy bed and standing the middle of a field, seeing a large planet in the sky about to crash into Eath (again, don't ask), I recognized it as Nibiru, the fictional tenth planet, and said "Really?! Nibiru!" in my dream. I tried to wake up but couldn't, and soon realized I couldn't move nor feel much. As quickly as it began, I woke up, still in a lazy state. Then It happened again, and then again (with different mini-dreams of course). When I woke up from the last one I really freaked out, and could of sworn I heard a voice. Then I went to sleep.

So, WHY does this happen? Have any of you had any similar experiences?

The largest are about 2 inches (5 cm) in diameter, it has a yellow, thin skin, and a gentle, lemonade-like flavor. Its flowers are small and white. One large tree grows in the yard and I've never been able to "officially" identify it, though to Mexicans they are known as "limas", and that's about all I know about them.

Google turns up nothing, so does anyone know? Thank you :)

There's several peach and nectarine trees in my backyard, and after I'd eat the fruit, my small dog would often chew on the discarded seed until reaching the "nut" on the inside and eating it. One day me and my sister decided to try some for ourselves, and cracked a few open we had found littered near the tree. I ate a few "peach-nuts" myself. That was years ago.

After learning these pits are full of toxic hydrogen cyanide, I wonder, why didn't we die or experience symptoms? Why did my chihuahua not die after ingesting so many? I've read even one can be fatal to small children/pets, so whats the deal?

Like on a planet or moon similar to Europa (Jupiter's moon) where little light penetrates the global ocean, how would this creature navagate its surrounding? How do deep ocean animals on Earth hunt ? Electrolocation? Ecolocation? Or would it create its own light to see/ attract prey? I know aliens are purely hypothetical, and the question doesn't make much sense in this section, but the biology section seems to devoid of life.

Yes, I know, Wii- HAHAHA

But seriously, I was playing one time when out of the blue, the screen turned black and I ended up in the multiplayer menu with a message saying "you have been disconnected from black ops multiplayer" (or something akin)

Then three days later, I went back on and was reviewing my classes when I realized......

-All the weapons had gold camo (and gold camo was unlocked for all others)

-I had two primary weapons per class

-I had Scavenger, Hardened, and Sleight of Hand on all my classes.

-Some weapons had 3 or 4 attachments on them

-I was level 50 prestige

-Had the most c.o.d. money possible

-I had unlocked all 10 custom classes

I DO NOT KNOW HOW TO HACK, HAVE NEVER HACKED, AND WOULD NEVER HACK.

IN FACT, I HATE HACKERS OF ONLINE GAMES (IF YOU CAN'T PLAY, THATS YOUR PROBLEM, NO NEED TO CHEAT). WHILE HAVING EXTRA CLASSES WAS QUITE COOL, I QUICKLY REMOVED AND CHANGED ALL THE MODDED GUNS AND WENT BACK TO NORMAL GAMEPLAY.

SO MY QUESTION IS.... has this ever happened to you and what would you do/did if it happened to you?

All poetic devices basically (like onomatopoeia, repetition/refrain, alliteration, metaphors, personification, etc.)

I already found several, but I feel more are in there hiding.

Please and thank you :)

"Radioactive"

I'm waking up to ash and dust

I wipe my brow and I sweat my rust

I'm breathing in the chemicals

I'm breaking in, shaping up, then checking out on the prison bus

This is it, the apocalypse

Whoa

I'm waking up, I feel it in my bones

Enough to make my systems blow

Welcome to the new age, to the new age

Welcome to the new age, to the new age

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

I raise my flags, don my clothes

It's a revolution, I suppose

We're painted red to fit right in

Whoa

I'm breaking in, shaping up, then checking out on the prison bus

This is it, the apocalypse

Whoa

I'm waking up, I feel it in my bones

Enough to make my systems blow

Welcome to the new age, to the new age

Welcome to the new age, to the new age

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

All systems go, the sun hasn't died

Deep in my bones, straight from inside

I'm waking up, I feel it in my bones

Enough to make my systems blow

Welcome to the new age, to the new age

Welcome to the new age, to the new age

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

Whoa, whoa, whoa, whoa, whoa, I'm radioactive, radioactive

Like all hats, buckets, explosives, hand tools (pickaxes, etc.), machinery, lighting, that you can think of/know. Did the mine shafts have electricity? If not, around what time did they shift from kerosene lamps to electric lights? Please explain. Thank you in advance :)

Clicked print, everything seemed normal, but printer didn't do anything. I noticed a blinking printer icon near the clock, and it said "1 document(s) pending for Administration". I tried to print it again, but that just changed it to "2 documents(s)". Then tried deleting the documents on the Queue, but only one deleted, the other just said "Status: Deleting - Printing" and stayed there. Not very experienced as you can see... help. Please. (I have Windows XP)

H2 (Diatomic Hydrogen), NH3 (Ammonia) and CH4 (Methane). In nearly equal amounts at 1 bar at 20 degrees Celsius.

As a side question, does hydrogen exist in a diatomic state in the atmosphere?

I often hear life couldn't survive on a planet with to much axial tilt, and that it would surely be nonexistent if the planet had none at all. Then we make things known as "habitable zones" where we search for life (I think the term should only be used for human space colonization/terraformation purposes). Is this a mistake? Could we be overlooking things?

With so many factors people see as the Earth of being perfect (distance from sun, large moon, magnetic field, short- but not too short- days, ozone layer, carbon-rich crust, large amounts of water, geologic activity and plate tectonics, etc.), could is this planet really be unique in the sense that it is perfect for life? Or could a completely different biosphere sustain vivacious, varying life like on Earth?

I ask lots of questions so please don't answer "It's just speculation".

I can very easily pass a science test i didn't study on, but can't solve a damn logic puzzle (i.e. http://www.logic-puzzles.org/). A lot of people tell me I'm smart but lack common sense, and some people even think i'm a little dumb when it comes to "the real world". Have been nicknamed the "Nutty Professor" by past teachers, if that relevant somehow. I guess you could say I'm introverted, and not very "street smart" (whatever that is). How can I improve by logic thinking skills and "practical intelligence" levels? Do I need to go out more (like experience new things)?

It's also very hard for me to remember people's names, and do you think IQ and personality are connected? And would finding out my own IQ make some of my many questions easier to answer?

I heard about it a while ago, I think you needed the object's orbital radius (semi-major axis) and the solar flux of Earth (1367?), but I forgot how the equation goes. Thanks.

Ah, fellow astronomy and space members, aren't you glad one of every 5 questions isn't about 2012 anymore? Did you win any bets? How was your "doomsday"?

Finally we can get back to science, and stop arguing with idiots.

It seems they all have similar atmospheric composition, so why is Neptune blue, while Saturn beige?

In this book ["Planetology", published by national geographic] there is a table of near-earth asteroids, their possible impact date, size, and probability of striking Earth. The second down is shown as "2008 AP4". I looked this up on the web, out of curiosity, but cannot find anything on it. Is it a typo? The book states its 1,279 ft in diameter and has a 40 in 1 millionths chance of hitting earth sometime around 2089-2100.

Thanks if you turn anything up on it, or find its name has been changed.

In a near vacuum, in outer space, traveling 0.1 Astronomical Units every 1.5 Seconds.

I understand how ocean or desert planets could exist, but could things like global forests or swamps exist?

I doubt it because seems you need large bodies of liquid water to make enough rain to support flora, especially that widespread. Or is it possible because a lot of the moisture would be trapped in the atmosphere and plants could get it directly from there?
