    The link below links to the Department of Energy’s website, where they have a page called “ask a scientist.” The answer to this question is a little complicated, so I am quoting the scientist from that page, named Vince Calder, directly. His answer is the following:

    “When ‘space’ began to form billions of years ago, gravity began to take over in space-time wrinkles. So ‘matter’ mostly hydrogen and helium began to collect into galaxies, stars, etc. Since gravity always ‘wins’ on the cosmic scale, most elements (including gases, which I generalize from your term ‘air’) clumped into various celestial objects. Put over-simply ‘gravity’ swept space clean of matter between the various objects.”
