He proposed the laws of gravity
Not exactly, he proposed laws of motion governing bodies experiencing gravitation, which was ascribed the generic description "force", which allowed him to use math to quantify it. What does a force look like? How much does a force weigh? Can you store force in some kind of force battery? Can you use the force?
It's not a dodge, it's just a fact, Newton didn't imagine "gravity" as a property of matter, and as a force it's only metaphysically tied to matter. Newton's position was essentially that he had no idea what caused the attraction, but that it clearly existed, so he described it as best he could. Incidentally, he wasn't the first to do this, so calling it "newton's laws" really frosts my weenie.
I haven't said anything about it until now, but you reveal a lot of cultural indoctrination when you call it "Newton's" laws. If you aren't from a european culture you're likely from one that's been economically and socially dominated by a european culture. But then I guess you could say that about anyone in any country.
Further, outside Earth's embrace, gravity fails utterly. It can't accurately describe something as ubiquitous as galaxies without resorting to "unobservable" stuff like "black hole" and "dark matter". It can't explain simple phenomena like the pioneer anomaly, just to name one. It can't be used to accurately determine the masses of the planets, because gravity's "laws" are mooted with respect to charged bodies able to interact electrically, which describes every body in the solar system and everything we can see in space.
And none of this bears directly on the electric star model or on plasma cosmology. Whether or not gravity is something real we have to contend with or a stark misunderstanding based on preconceived bias, electric star models make essentially the same assertions and predictions. Since gravity's rules are mooted by electromagnetic forces, we may ignore them. If they're not real in the first place, we may ignore them. Bottom line: we may ignore them
