Does every whether have to be followed by an or?
That is, is whether a correlative conjunction which requires or as a counterpart, or is whether able to stand alone with a single possibility?

No, not at all. The only time "whether" requires an "or" is when the phrase "whether or not" is being used. For instance, I wonder whether or not we'll go to the movies tonight. Otherwise, whether just by itself is fine. For example, I wonder whether we'll go to the movies tonight. It's essentially synonymous with the word "if."
