“Evidence” was based more on hopes and beliefs than on any type of real evidence Conclusion: Made clear that the Moon and the planets really are other worlds and life may be elsewhere How can we distinguish science from nonscience? Modern science seeks explanations for observed phenomena that rely solely on natural causes Science progresses through the creation and testing of models of nature that explain the observations as simply as possible A scientific model must make testable predictions about natural phenomena that would force us to revise or abandon the model if the predictions do not agree with observations Occam’s razor: the idea that scientists should prefer the simpler of two models that agree equally well with observations Pseudoscience: false science; e.g., psychics
