In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery. Since Thomson’s discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?

The law of universal gravitation states that both mass and distance of objects affect the gravitational force between them. Gravitational force increases as the mass of the objects increase. Gravitational force decreases as distance between the objects increases. Why are these statements considered scientific law, and not scientific theory?
