In general, would vegetative matter, or any living material for that matter, decay or decompose if left in the vacuum of space? Or would it be preserved for eternity?

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

The sun isn't expected to exhaust its nuclear energy for another 4-5 billion years, but when it does, it's supposed to turn into a white dwarf.  On Earth, pretty much everything would die after getting roasted, but that's a bit too far down the line to worry about.  There's a better timeline here: http://www-astronomy.mps.ohio-state.edu/~pogge/Lectures/vistas97.html\n\nPerpetual motion is pretty tough because there's always going to be some sort of friction, which causes heat and energy to be taken out of the system.  You then need to keep putting energy into the system for the motion to continue.

nothing. even the vacuum of space has energy flowing through it. So, in theory, a perfect vacuum is nothing.

Everything is made of atoms, genius...\n\nC. nothing would be left.

Outer space must go out forever, else there would be an end to it.  If there were an end to it, what would be on the other side of the end?\n\nI can live forever, and I'm not interested in the "outer limits."  Plenty of interesting things all around.

You are open to the absolute vacuum of space. Now if you understand vacuums the tighter it is the higher potential pressure on anything containing matter. Therefore when exposed to a vacuum all the fluids of your body will rapidly escape with the thin layers of flesh not even slowing them down. Think of a water balloon that has been overfilled.

i never really thought about it and so i was just going to say that temperature doesnt matter because its a vacuum and is dealing with the pressure... but when i thought about it... come to think of it, i do have an answer for you.  the temperature would be zero kelvin, absolute zero.\n\n in an absolute vacuum, the pressure would be 0 if there were no particles, because the more particles you cram into one place, the more pressure there is because p=F/A pressure equals the force of the particles divided by the area of the wall of the container, so with no force of particles(since there are no partiles), the pressure would be zero.  in an absolute vacuum, there are no particles.  Now, if the pressure is zero, then according to the formula PV=nRT (which is just the ideal gas law formula,) if P(pressure) equals 0, i think that means that T(temperature in Kelvin)would also be 0 which would mean that the temperature would be at absolute zero(which is defined as the temperature where all matter stops moving.. not that this would make a difference because there are no particles there because it's an absolute vacuum.  \n\nThis is what i suspect and to confirm my beliefs,  it is consistent with the fact that someone else said that outer space was 3K, and although it's very close to an absolute vacuum, there are a few particles and atoms of gas floating around there, and so it is not quite an absolute vacuum, and the temperature is 3K, meaning it's not quite at absolute zero.  so it stands to reason that since temperature decreases when pressure decreases, that in an absolute vacuum the temperature would be absolute zero, 0 kelvin.\n\ni hope this is a "good answer" and that i made sense while i took you through my reasoning :)

Mars lacks the gravity to hold onto an Oxygen atmosphere for any length of time.\n\nBasically the average speed of the molecules from thermal vibrations is sufficiently high that some of them are moving faster than escape velocity which means that those molecules will escape forever.\n\nA good rule of thumb is that if the average speed is more than about a tenth of the escape velocity the planet won't hold an atmosphere for very long.  There are ways to calculate a half life of a species in an atmosphere but I don't have the information with me at the moment.

The universe is theorized to contain dark energy and dark matter. There have been some confirmation of it's existence but really just speculation at this point. The idea of dark matter had been identified by Einstein but it wasn't till the discovery that the universe is accelerating it's expansion and contains up to 70% more matter that the idea of dark matter and energy became serious areas of study. If you mean a vacuum to mean absence of air it is a vacuum but within that "vacuum" there definitely is matter.

By the time that happens the Earth will have already been destroyed by the sun. But if the Earth was still around, it is highly unlikely that we would collide with any matter at all, since space is mostly just dust and emptiness, believe it or not. We would likely have a higher-than-usual amount of dust moving about the solar system, however.

Science is limited to the physical. Your soul is eternal. The Bible deals with what is eternal where science cannot venture. The physical realm will pass away, and science will pass away with it. What you want to do is latch onto that which will last forever, and that is the Word of God.\n\nMatthew 24:35\nJesus said, "Heaven and earth will pass away, but My words will by no means pass away."\n\nHowever, with a little study and reference, you can find proof that God DOES exist. My writing at the link below shows how this is possible.\n\nhttp://schnebin.blogspot.com/2006/05/gods-word-proven.html\n\n*Emma* - God can be known personally. THAT is the essence of the Gospel. Science will not help you in that venture. God is a Spirit, and those who wish to know Him must seek Him in spirit and in truth. Read the above link to start your own quest.

Assuming this is possible the end positioned inside the event horizon would be broken down into it's individual atoms and would cease to exist.  However some scientists (me being one of them) think black holes are only one end of a worm hole and that when you reach the event horizon you are expelled out of a white hole into another universe.  Think of a white hole as the polar opposite of a black hole, instead of consuming every thing it expels everything

"Space air"?\nIt is really hard to decipher what you are trying to ask.\n\n"Space" is pretty close to being a vacuum (for all intensive purposes for us here on Earth), thus there is no "air" in space.\n\nThe concept of there being some type of medium in space which everything travels through (the idea of an "aether", the material which allowed light to propigate through empty space) has since been disproven over well 100 years ago by the Michelson-Morley experiment.

"Yup. There is nothing after death. It is just like switching off a light bulb."\n\nbut on the other hand the electrical circuitry and infrastructure that powered the light bulb is still there even when the bulb (earthly body) burns out . Bung a new bulb in and who knows?\n\nI'm inclined to believe that when this earthly body burns out the power that motivated it is still there - it's either latent or seeking for a new form.  The "light bulb" is just the external manifestation of thousands of miles of hidden cable, switches, relays, et c, and just because the bublb goes it doesn't negate the existence of all this stuff....

There's no oxygen in space but we all breathe. The sun has enough gravity to keep the oxygen inside it just like Earth but even more so. However this oxygen isn't for burning like we would burn wood. It is part of the cycle of nuclear reactions going on in the sun. The gravity of the sun is large enough to keep the mass of gas concentrated enough to be able to sustain such nuclear reactions.

That completely depends on the conditions in the soil- If its fairly dry, you would have a hard, dessicated tissue much like jerky.  In a moist but anoxic soil, the tissue would be well preserved.  In normal moist and oxygenated soil, there would be very little tissue left.

In all actuality, your question makes no sense.  If you were to take out all the "space" in matter, there would be no matter.  Matter is basically made out of energy and forces interacting with each other.  If you compressed the universe into the size of a refrigerator, you wouldn't have matter anymore.
