The article says that the derivation showing the need for “dark matter” are based on the wrong set of equations - equations much easier to solve, but are only correct for simpler systems ( The correct equations are mathematically similar to Maxwell’s equations - and plasma physicists are the meanest mofos there is when it comes to E&M. No short cuts there. So some plasma physicist tried to find what the dark mass of the universe is of the correct set of equations are used. He was surprised that the solution doesn’t exist. When he solved it, he found out that dark matter doesn’t exist.
