Nature would have you stay as you are.
Try picking up a big rock. It doesn’t move easily. Now picture a soccer ball kicked to infinity. Objects of nature prefer to stay as they are. Holding still when at rest and on the run, once begun. That’s the nature of objects, from atom to star.
Nature makes no effort to change in this way. It’s safe, in this sense, to say she’s lazy. The Latin for lazy is inertia. Vice versa, staying the course unless the object is otherwise forced. So Nature is lazy to change the ways of her nature.
