In his 1963 lecture at Caltech, Feynman explained about the weird motion of Uranus and its effect. Specifically, Uranus showed perturbations where no other planet was. This caused some people at that time to doubt Newtons Laws. But two mathematicians in the 1840s independently calculated the position of where the not-yet-observed planet would have to be to cause such perturbation. The observatories confirmed their prediction and thus a new planet called Neptune was discovered. Suppose that observatories had looked at the indicated position and had not actually found the predicted planet. What then? What new question would this outcome pose for the scientific community? How could they test other explanations for unexpected motions of Uranus?
