Motion

Movement
What causing an object or such to move? What does it mean to move? What is motion. One simple way to answer the latter question is to look at what is the opposite of motion. One term for this is if an object instead of moving, is set stationary. The object stands still, no going one direction or another. Is it possible for anything to be truly stationary? For do not all physical things in The Universe and beyond, even air, have atoms that are in constant motion?
Well, perhaps a true vacuum is motionless, for it is the absence of anything of substance. One might say, well than this answer the question. However, the rebuttal to that assumption is that a true vacuum, even in space, is only theoretical and that no true vacuum has ever been found, as of today. So it must be said that there is no such known thing as something that is truly stationary, therefore everything ever is in motion in some capacity, whether we can see it or not. Therefore motion seems to be the law of the land, figuratively.
So for the first question, what causes an object or such to move, the answer to that is force. Whether that force be a push from some other object or such, or from the force of the atoms that create the object make due to interaction with one another.
​Finally, the second question asks, What does it mean to move? Well, to move is simply answer by the answer to the answer to the latter question, it means to not a truly stationary. Therefore motion is in all known things and all known things move in one way or another. Motion is what 'moves' The Universe.
