THERE IS NO SUCH THING AS A TRUE VACUUM... PERIOD!\n(exerpt from a previous answer)\nContrary to popular belief, empty space is not empty, and it is certainly not a vacuum. In fact, a true vacuum has never been created, anywhere, where the atomic count is zero.\nresearch it, its true.\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nOne day the misinformation of space as a vacuum will finally die out.\n\nSo YES, a dead body would decompose eventually, How long would depend on the bodies proximity to other planetary bodies such as the sun, the earth,etc., and how long it stayed in space before falling into an orbit around one of those entities.\n\nspread the knowledge

About 1 atom for every 32 cubic centimeters\nActually, There is no such thing as a true vacuum.\nA true vacuum has never been created, anywhere, where the atomic count is zero.\nThere is always atomic content left to fill the "vacuous" space. No one has ever been able to creat a true vacuum.\n(exerpt from a previous answer)\nContrary to popular belief, empty space is not empty, and it is certainly not a vacuum. \nresearch it, its true.\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nOne day the misinformation of space, or anything else, as a vacuum will finally die out.\n\nIf you are referring to a vacuum cleaner.... then dirt.\n\nspread the knowledge

I guess it would explode because of the difference in pressure... but then again this is with a live human... not sure about the dead one.\n\nThis site might be of help:\nhttp://en.wikipedia.org/wiki/Human_adaptation_to_space

Yes, If the mass of the everything doubles than whole universe will get shrunk and the heavenly bodies in the space will collide and get destroyed. because more the mass more the gravitation force. chances gettin hitted by a asteroid will increase. People will find difficult to walk, aeroplane will crash down and satellites may fall down. we've to give the rockets more spped currentl which is 11.2 km/s. so many things happen.

For a very short time, yes. People tend to forget about what's called "dead air spaces". Yes, you're exhaling some co2, but a good deal of that exhalation is still o2 ( it's not all used in a breath) and even more so in dead air spaces. These are areas in your body from the top of your lungs to the tip of your lips, that don't do any gas transfer to or from the blood stream. It's still normal, oxygen rich air in there.\n I also disagree with what one person has stated here, that artificial respiration is only a method to get the lungs moving. \n It IS in fact a method of oxygenating the blood stream and keeping a victim viable in the absence of their breathing on their own.

The air would rush away from the earth.  The average speed of an air molecule is about 1,000 miles per hour, so the initial speed of the air rusing away would be about 1,000 miles per hour.  If you were outdoors, you might be carried away with the air.\n\nAs the air pressure dropped, you would see fog everywhere and you might feel chilled because when air expands the temperature drops.\n\nWhen the air pressure was low enough, the fog would disappear because the fog droplets would boil away.\n\nThen, as the pressure dropped more, it would become excruciatingly painful as the gasses came out of (exsolved from) your blood.  Blood would bubble out of all of your body openings, ears, eyes, nose, mouth, others.  Your body would blow up like a balloon and your skin might burst.  This would all be unbelievably painful.\n\nThen you would loose consciousness from a lack of oxygen and die.\n\nAll of this would happen very quickly, maybe in a minute.  The space shuttle flies at an altitude of 100 miles because there is no air at that height.  Since the air is rushing away from the earth at 1,000 mph, all of the air would be gone within 10 minutes.

Well actually on thing first: the reason why on a spacecraft or in a spacestation air is sucked out into space, is because gas as being air rises and fills as much room as it can expand, but as space is empty it will try to consume that space. This gets vacuum mixed up with air/gas escaping.\nSo nebulas, dust, gas and other remnants can stay in one place. Although the gas expands and converts dark matter to a larger mass (process=0.000023% conversion). As also the mass expands, the same way as galaxies expand the universe like the particles of the nova gas.\nIf a spaceship or spacestation was to explode it would be a flash of light expanding on the particles that were ejected by the explosive expansion, feeding on the explosion power. Basically the explosion would push out the mass rather than the mass expanding on itself. The term of explosion in space is not yet literally confirmed but some people name it a "nova". Although it means "explosion of gas from gas cloud" to our sense. There may not be air but the dark matter would provide a vibe cushion. Although a smaller sound it will still be a "sound" that probably only certain ears can hear as well as the energy production would create a certain spectrum of sound.\nOnly man-made satellites have been broken and fallen to Earth, but I don't know of any explosions, actually they're 50% explosion proof I think.\nAlso think as if you're in a spaceship and you are travelling at 100 mph all heavier loose matter will be forced down by gravity and weight as liquid and gas and air as heavy loose matter to be heavy and travelling will cause these heavier loose matter to be forced into your face as you are gaining speed this is a vacuum of force "forced matter vacuum". With the door wide open while travelling will cause a pump or "matter pump vacuum". Making loose heavy matter to be forced to the bottom in gravity and backwards by force vacuum "also 'gravitional vacuum' ". This is called the "circulation vacuum". Like liquid you would see heavier elements go to the base and the lightest at the top this is the same physic as that of forcing heavier loose matter back in a spaceship as "circulation vacuum". This force is relative to gravity "relativity".

Your heart stops beating. Your synapses slow their firing until you are brain dead and no electrical current is flowing through the nervous system. Your body will generally expel any waste matter (air, urine, feces) being held. Sometime around this time, you will either discover that there is an afterlife of some sort, or you will blink into nothingness, with absolutely no consciousness to be aware of the fact that there is no afterlife. The body will begin the approach to rigor mortise. And bacteria will begin decomposing the body. Years and years later, only ash (and perhaps fossilized bones) will be left of your body. If there is an afterlife, you will never be able to tell anyone. If there isn't, you will never be able to tell anyone. Those who say they know the truth about the afterlife, either way, are not intellectually honest. Which is why this question will continue to evoke philosophical debate ad infinitum.

well unfortunately, outerspace is a whole lot of nothing, so it doesnt have to take up any space.  granted there are molecules floating around out there, but for the most part there isnt any matter in empty outer space

A human is naturally a little lighter than water so will float naturally.\nImmediately when a person dies his body will begin to get rid of a lot of oxygen, and other gases, primarily from the lungs and the blood stream.  When these gases are expunged from the body, the body will sink.\nAfter a while the remaining gases will begin interacting with the tissues and muscles and chemicals in the body and those gases will swell up, causing the body to float again.

This is actually a good question, because all the shuttle deaths we heard about occurred while going into or down from space.  However, in 1971, three Russian cosmonauts of Soyuz 11 were killed by exposure to vacuum after undocking from space station Salyut 1 when a valve accidently opened.  Their craft subsequently landed normally, but a recovery crew discovered their dead bodies.

theoretically, YES.\n\neven space is not a complete vacuum.\n\nthe "tightest" vacuum exists in intergalactic space with a density of one hydrogen atom per cubic centimeter.\n\n"sound" is the perception of vibrations in atoms as percieved by the human ear.  \n\ntheoretically, a large enough shockwave ( e.g. a supernova ) could compress enough of these rare atoms in space to move your eardrum ( if the radiation doesnt kill you first ! ).  \n\nif you consider the music coming out of your stereo amplifier to be sound, then consider a microphone that is sensitive enough to pick up these minute vibrations in space and amplify them to your speakers and you would be listening to their sound ! ( in space ).\n\nin short, the VIBRATIONS are there even in the thinnest vacuum, it is only a question of being able listen to them !

Is it within a vacuum?\n\nIf not, and if through your above given conditions resulted in air being compressed or what have you then I guess it would.

Hi. Space is not a complete vacuum. There are a number of hydrogen atoms throughout. A few per cubic meter. But if you think about it, light can reach us through billions of light years of space, so it is a very good vacuum if not a perfect one. And any material should SLOW the light. 'c' is still the fastest speed.

Yes, of course there is litter in space, AKA "space junk".\nStuff does get lost durring space walks, stuff will fall off a satelite, debris is in orbit around the Earth.\nAll that space junk is being tracked in its orbit along with all the other satelites and space vehicles since they pose a collision threat.  You need to know where all the potnetially dangerous stuff is up there when you launch something in to space so you dont put in on a collision course.\n\nEventually, all the stuff will burn up in the Earth's atmosphere after its orbit degrades.
