Physics teacher: Now, we will talk about centripetal forces.
*puts up notes on the chalkboard*
Physics teacher: The curriculum used to have centrifugal forces too, but it is illegal now, and all the pages in the textbooks about it are gone.
Student: Why is it illegal?
Physics teacher: Because it is, in theory, not proven.
*students puzzled*
Physics teacher: It is like religion! Non-existent.
