Well, it would be nice to see more admissions that how gravity and spacetime works is actually still mostly a giant unknown. Accurately prediction the motions of what you can easily see and understanding the full capabilities of something is very different. We are still stuck in a lot of science Elitism where questioning the LAWS OF PHYSICS gets you attacked and ridiculed. It also gives rise to a lot of pretty crazy ideas trying to form math and logic around such big assumptions, like UNIVERSE SIMULATION.. because how else could gravity do that? Is that really the right direction to take the question? Fundamental forces and top theories are just cheap cliff notes at this point in human existence. Don't take them so seriously you forget all the other possibilities or we all just wind up making the same mistakes.

Expect the unexpected! Our basis for all human knowledge is from an almost infinitely small sample size. It's too bad the universe doesn't have time-lapse instead of just history vision. Having to wait forever to know anything for sure is a pain in the butt!

The people trying to find weirdness in the laws of gravity have been trying since at least the 80s whereas Einstein keeps getting proven right time and again in ever more extreme circumstances.

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.)
