How Do Objects "Hang" in Outer Space? I'm wondering how it is that things in outer space just "float" and don't "fall" down or collide into each other? In the ocean, for example, if you put objects with weight into the water, they will generally sink or I guess they can float too. But how is it that objects in space don't seem to "fall" and just stay suspended in the air? Or am I missing something?
