What is in space instead of air?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: Why do we need to wear a space suit in space?; Why do things float around in space?; Why do stars twinkle? and more...

Well, in space there is the lack of air. There are some tiny molecules and other things out there, but the air in our atmosphere is really concentrated around the surface. As you go further out in space there's less and less air, and so, basically, when you get out into space, and it's called a vacuum, it is the lack of particles, the lack of substance there. So, vacuum is nothing.
