When scientists propose a new theory, they must explain how it works. "The Secret," on the other hand, gets in deep trouble when it tries to explain the mechanism by which the "Law of Attraction" supposedly works. According to the idea, our thoughts somehow send out vibrations that something in the universe somehow deciphers and responds to. If we want to be thinner, or have a new car, the universe will somehow provide it if we think about it. Positive thinking is easier than diet and exercise or earning money to buy a car, but even if the "Law of Attraction" exists, how exactly would the pounds come off, and the new car appear?
