infinite space

I haven't read the five pages of this thread, but has anyone defined space and universe yet?My definition of space would be the area in which matter exists. If you have a cubic one foot box full of air and it would be possible for you to remove all the contents of the box, including elements and light rays, etc, you'd still have a box of space. Let's say the box is a steel box half way between the earth and the sun where there's no pressure on it.I define the universe the old way, being everything that exists, including infinite space, i.e, area.I see your definition is similar to mine, V, but you have two kinds of space and I have only one. My definition covers it all.[This message has been edited by buzsaw, 03-23-2004]
