I don't quite see what the fuss is about. Anyone with an elementary understanding of physics knows that the First Law describes the motion of an object in the absence of any outside force. And anyone with an elementary understanding of the universe knows that there is no such condition; no matter how minutely, every object is at the very least affected by the force of gravity, along with possibly atmospheric friction, friction from contact with a surface, collision with other objects, even dust particles. This doesn't change our understanding of Newtonian physics.

What's all the fuss about? In school, almost 70 years ago, we learned that forces such as gravity would alter the motion of a body, and could even cause it to move in a circle. (orbit)
