I don´t give a daim for your personal, emotional and eternal nit pickings. And you obviously automatically think debaters don´t investigate what they are talking about.So you have no clue? At least you admitted that. The first observation, and the first piece of evidence for Dark Matter was that galaxies rotate faster than the observed made would indicate. You still did not ask properly, but since you admitted to not having a clue I decided to help you a bit.
Grow up man!
