> I do not understand how they jumped directly to matter being the solution to the gravitational oddities This never happened. "Dark Matter" is just a name for a phenomenon. Galaxies rotate as if they have a bunch of matter in them that can't be accounted for by looking at the light coming from them. So it's "dark" matter. Get it? No one has a "solution" here. It's a problem, and it needs a name. What would you prefer?
