what's in space, no air, nothing?
486001
Space is generally considered a vacuum, meaning there is nothing, no air or anything.  There is a little bit of gas but it is so spread out that we consider it to be at zero atmospheres (pressure of air at sea level on earth is 1 atmosphere). There are a few hydrogen atoms per cubic centimeter in space. At sea level on earth, there are 25 billion billion molecules of gas per cubic centimeter.\n\nThe temperature in space is about 3 Kelvin, or 3 degrees above aboslute zero, or 460 below zero in Farenheit.\n\nThere is also virtual energy and virtual particles that are constantly popping in and out of existence, but on such a tiny tiny scale that it has no direct effect on humans. But if you are getting into detailed questions of motion of bodies in space or how light goes through space, it makes a difference.

The space has no air i.e. it is vacuum. A sound needs some medium to travel. As there is no air around the moon the sound does not travel and thus one can not hear anything on the moon.

OK... let's get graphic.\nFirst off..... you'd die! No way around that!\nWhat would kill you first is the question.\nSpace is incredibly cold, so instant exposure to space would freeze almost all liquid in your body solid.\nSpace is also a HUGE vaccum, so all the air would be sucked out of you either while you're freezing solid, of during your freezing process.... either way, you'd suffocate if you didn't freeze by some miracle.\nSpace has absolutely no compromising pressure like the inside of our atmospere. Our bodies are used to a certain atmosperic pressure. Without it (I.E in space) if you didn't freeze or suffocate, eventually the lack of pressure would collapse our fragile bodies.\nThe possibilities for death are indeed endless.

As my education impressed on my mind; there is no empty space.  What we think of as "space" is not empty but a constant dance of virtual particals (protons/antiprotons, etc) constantly appearing out of the vacuum travelling a short distance, then touching and annihilating into nothing once again.  \n\n"Empty" space is filled with these interactions which I believe are known as vacuum fluctuations.  The law of "convservation of energy" is really something that holds on average.  Another principle called the uncertainty principle states that we cannot measure simultaneously the energy and time of a (system of particles?) more accurate than a constantant called h or hbar (a very small but finite number). \n\nSo in theory the universe can "borrow" energy from nowhere as long as that energy is returned before the h bar uncertainty in time runs out.  And thus "empty" space is filled with these vacuum fluctuations and is not really empty after all.  Of course I don't think I explained that too well.  See "In Search of Schrodinger's Cat" by John Gribben for a more coherent description

where ?\nin outer space. there is room enough.\nor am I wrong ?

that means empty space

Actually, 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\n\nspread the knowledge

No Air --> No Pressure --> You explode from inside

In outer space there are some gasses but not enough in any one place to provide a medium for a sound wave to propagate through. Asteroids and meteors are silent until they enter an atmosphere.

temperature itself is a property of matter. so, in space, where there is a near perfect vacuum, there is no temperature.\n\ntemperature of stars / dark matter in space can be measured by studying the radiation that is emitted / absorbed by it.

Unidentified Flying object\n\nusually "aliens"!

only in space where there is no air\n\nof  course there no clouds either but electrical spark can still be produced artificially\n\nedit: "a mile away for every second counted: -- make this about 4-5 seconds; the sound speed is about 300m/s

It is not a vacuum.  The density of space is 0.1 - 1000 atoms/cm3.\n\nPlanets are made of condensed interstellar matter.

Nothingness.\n\nOr maybe it's encroaching on another Universe?  Hmmmm......

There's space up there. And since space is limitless, I guess sky is so too!

You answered it , blackness .No universe, no planets .that would be nothingness  ! Not anything !
