I am a skeptic. I choose not to accept extraordinary claims , simply because they have been made. I want to know on what evidence the claims are based. I want to know who is making the claim. I want to plug the darned thing in and see if it works.

You can learn your future, shed pounds without dieting and read about people who have been repeatedly probed by aliens. Skepticism, in the service of science, is a tool for evaluating an observation or a hypothesis. It is in the challenge of a hypothesis that a theory may rise or fall. Well, the truth is, sometimes you can't. Some claims are simply outside of science.
