Space make up

[KevinWere]

I want to know what the general make up of space is as in the gases of the space excluding planets and gas clouds. The general space the so called nothing gas or really just nothing?

Space expands where there is no gravity to overcome it. If you have a cubic lightyear of space devoid of any atoms and energy, it would still expand, meaning it can't be nothing! <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.
