How do communication satalites float in space without crashing to earth.

Why does the moon not fly off?

Is there somoething else other than gravity?

Objects fall to earth at the same speed, all this does not make sense.

If there is an end, lets call it a wall. How thick is this wall and what's on the other side?

More space!
