What does dancing have to do with science?
Pretty much nothing at all. If you wanted to, you could analyze how dances become popular, or what kind of dances are the most difficult to learn because of which muscle groups you have to train, or something along those lines. In reality, the two aren’t linked, but you can force them to be if you find it necessary. Anything can be scientifically analyzed, and that’s about as related as science gets with a lot of things.
