Is space filled with matter? Or antimatter? Is it really absolute nothingness (aside from where planets and stars are etc.)?

Space are dimensions. There are three space dimensions that we concerns ourselves with, given that they are the only three we can comprehend: width, breadth, and depth.
Space as commonly referenced is a massive expanse of these directions that doesn't contain a great deal. A sprinkling of atoms around, plenty of photons emitted by stars, the occasional star, planet or other significant celestial body. There is a lot less matter drifting around in interstellar space than between planets in star systems, and even less in that cold, lonely intergalactic space.

Ther's no simple answer since there are a number of different "spaces" that everyone from topologists to astronomers deal with. One view is that "our" space is the lower-order matrix of a higher-order space which can transmit energy and support matter/antimatter. In fact, you can turn that around and say if those are present, then you dealing with "our" experience of space.
That doesn't help much, huh? And it gets worse. "Space" is expanding and everything in our universe is getting dragged along with it. Even worse again, there appears to have been a point reached in the expansion when a sort of hyperdimensional tearing effect began--oh joy--which may have given rise to a new fundamental force that now causing the universe to accelerate its expansion.
It's a tough question. I'm tired. And that's the best I can do for you right now. Good luck!

Space is the area that is very nearly a vacuum, meaning it has particles in it, but they are very sparsely located... It has a very low pressure, on the order of 10^(-15) kPa (for comparison, sea level is 101 kPa, a difference of 10^16)
It isn't really filled with anything that we know of, unless you count radiation, which isn't matter or antimatter...
another thing to notice, space is not uniformly dense, the average density is less than one atom per cubic meter, but it fluctuates from very dense areas (planets, stars, etc) to areas that are nearly perfect vacuums (ie intergalactic space)

I haven't found any descriptive explanations that make sense to me, but maybe the best description is mathematical and expecting a description to "make sense" is no more relevant concerning space than it is concerning fundamental particles or relativity?
Stating that space only has a few atoms per square meter, or is a sea of "virtual particles" that appear and disappear, seem to me like descriptions that circle back on themselves: what contains those few scattered atoms (what is space?!), or, what is the medium into which virtual particles materialize (what is space?!)

Space is the area around the planet your standing on.
Matter, plasma, dark matter and light, no antimatter.
All space has stuff, it is very thin in places but it's there.

Space is just room. Like space for one more on the bus or space for another student in the class or enough space to play badminton in the back yard. Outer space is the term for all space outside the Earth's atmosphere.

Space is not nothing it is full of particles just no life. you have to have temp and warmth to have life.
this is an hella tight subject and even though it seems ******* boring it really is fascinating i recommend googling it DONT YAHOO SEARCH it. yahoo sucks for searches
