if there's no such thing as perpetual motion is there such thing as perpetual stability? doesn't that have to do with inertia? if everything's at rest until its effected by an outside force are there objects in the universe that are never effected by an outside force? but the universe is in constant motion. its constantly expanding for one thing. so can anything ever be described as being at rest. just curious.
