Reply to comment by phdoofus in Lopsided star cluster may disprove Newton and Einstein, controversial new study claims. An uneven distribution of stars in several nearby clusters may offer evidence of MOND — a controversial theory of gravity that disputes Newton and rejects the existence of dark matter. by nimobo
Is he proven right though? Or is he just the closest to the right answer. Again, dark matter and energy haven’t been observed. We just know without adding them to the formulas, galaxies don’t stay together. So it’s either he was wrong, or we still need to “find” extra matter that we can’t see.

When their theories keep getting ruled out by measurements, e.g. gravity wave speeds, etc, then you have to wonder if they're not on the wrong track. Even current modified newtonian gravity theories still require dark matter to match observation.

No doubt. I just don’t like the demeanor levied against Newtonian doubters. This isn’t a flat earth situation where it’s frankly just not debatable. There’s real questions as to our understanding of physics when we get to the scope of galaxies and larger.
It is possible that dark matter doesn’t exist and we missed something. (Not saying you in particular are shaming, just making a point.)
