Process of Science: A prediction based on Newton's theory of gravity led to the discovery of Neptune.

Question

Quizplus · Accepted Answer

In the early 1800s, scientists observed Uranus and noticed that its orbit did not match the predictions made based on Newton's theory of gravity. This led mathematicians to predict that the gravitational pull of another undiscovered planet was affecting Uranus' orbit. Further calculations led to the discovery of Neptune in 1846, validating the prediction based on Newton's theory. This is an example of the scientific process of using observations, making predictions, and testing those predictions through further observation or experimentation.
