As I alluded in the OP, Newton's theories were proven inconsistent back in the 1800's when they created telescopes powerful enough to track the orbit of Mercury.
The orbit of Mercury is inconsistent with Newton's theories.
Likewise, the orbits of stars around galactic nuclei are inconsistent with relativity, and modern dark matter is the same fake band-aid for the same problem.

The peer-review system has been purposely redesigned to ensure this doesn't work anymore.

I suggest you consider how Neptune was discovered - in the late 1700s astronomers noticed that Uranus's orbit didn't match up with Newton's equations. So while some suggested gravity worked differently far away from the sun, others suggested that the gravity of an unseen planet was causing the issue. A few decades later and they were able to directly find Neptune.

Or also consider that when Pauli discovered that beta decay seemed to violate the law of conservation of momentum, he predicted that there would be a bunch of small, super difficult to detect particles carrying away that missing momentum. We now call those neutrinos. Again, it took decades to confirm them.

So yes, assuming your model/theory is correct, but some invisible shit is causing your observations to not match up, and then looking for that invisible shit, is a perfectly valid way to do science. The idea that there is some sort of particle like a neutrino, but even harder to detect, doesn't seem like that big of a stretch to me.

Ask yourself OP, what sort of things would you look for that could distinguish between the dark matter hypothesis & the modified gravity hypothesis? Any unusual astronomical objects we could look for that would make sense under one hypothesis but not the other?

Ah, but we now know that while the rotation of stars in most galaxies defy Einstein's theories, a few dwarf galaxies have been discovered that throw a monkey wrench into things; their stars and dust clouds rotate in a way much, much, closer to what relatively predicts (and very differently from other dwarf galaxies that are visually similar). The dark matter hypothesis can explain that 'easily' enough - those galaxies have an unusually low amount of dark matter for some reason.

OK I'll bite.
A simple plasmoid with extreme energy density would both look and behave like a black hole, without the need for relativity.
Considering the recent "photo" of the black hole is 99.9% CGI, it's not evidence of anything really.
A plasmoid would require "invisible" electrical energy, similar to invisible dark matter.
The differene being that such electrical energy also explains the spiral shape of the galaxy, the formation and nature of stars, comets, inter-galactic interactions, etc. in addition to explaining behavior presently attributed to otherwise invisible black holes.

In other words, a much more solid theory than dark matter and relativity, based in hard science (electrical engineering) rather than speculative particle physics.

It's like they are hypothesizing concepts that have never been observed in nature or the sky in this context and trying to justify it with no evidence.

>I challenge you to prove this exists at all.
Learn to read. If you claim it does not exist then you have to actually explain the data which showed an effect consistent with redshift and precession. Note GR and black holes predicted these effects, which is infinitely better than coming up with an explanation after the fact.

It only works at short distances (120 AU) i.e. the same old scale problem.
Of course it works at that scale, for the same reason it works inside the solar system.

black holes have infinite mass of course they are going to keep shit orbiting around them regardless of distance

also most galaxies are spirals for a reason. What wouldn't make sense is if they had long straight arms. but they don't so it's fine.

also dark matter isn't fake matter it's just not illuminated. there's probably a lot of rocks and planetoids just whizzing through intergalactic space.

>> No.12269179

>>12269148
>black holes have infinite mass
This is incorrect.
For example, a black hole formed from the collapse of a star, has a mass approximately equal to the mass of the star minus supernova shed, plus the mass of anything else it sucks in.
Black holes have infinite DENSITY, and therefore infinite gravity ONLY at the point of the singularity.
If black holes had infinite mass, galaxies wouldn't exist, because the entire galaxy would be sucked in.

>also most galaxies are spirals for a reason
What reason?
No theory of gravity predicts the spiral shape.

>there's probably a lot of rocks and planetoids just whizzing through intergalactic space
I agree with this.
However imagine winning the lottery a quadrillion times in a row.
I'd say that's a good approximation of the statistical probability that all that random intergalactic matter (ahem plasma), in entropy/chaos, just HAPPENING to locate itself in perfect halos around every single galaxy simultaneously, in such a way to perfectly fix the galactic rotation problem for relativity.

Does it contribute to the galactic rotation problem?
Of course it does.
Does it resolve the galactic rotation problem?
That's quite a stretch.

Still can't read then. See equation 1 of each paper. In the case of gravitational redshift the effect is most significant for closer pericentres, for precession it's smaller semimajor axes combined with seeing more orbits.
>Until then, don't sit here and prop up these papers as if they prove something new or different.
You've entirely forgotten the point of this discussion. I cited these papers as examples of predicted and confirmed phenomena around the Milky Way's supermassive black hole. You claimed a plasmoid would behave like a black hole but wouldn't require relativity, so it should also explain these data. But as we have learned you were just making shit up.
>I asked YOU to cite your claims, first even.

Everyone one of those statements is wrong. Black holes have finite masses, not infinite. Elliptical & irregularly shaped galaxies are at least as common as spiral ones.

Of course.
But it's considered definitive and empirical, neither of which is correct.
It's a placeholder because something must be there to exert this effect, in order for relativity to still appear consistent.

Ah, but there are multiple, independent observations (not just the galactic rotational curve issue, but stuff like seeing gravitational lensing from areas with no visible matter) that make sense if dark matter is a thing, but requires all sorts of contortions & epicycles to make sense of with any sort of modified gravity theory yet proposed. At this point Occam's razor would say the dark matter hypothesis is the one with the least complications.

Correct, you can't prove negatives. This is not criticism of GR. Unless there is a model of this alternative lensing there is nothing to test. All that can be said is that GR predicted lensing and current data is consistent with those predictions.

Data. Tests. All of them have been repeated.

Not a controlled test, as I explained. There are cosmological tests which are insensitive to small scale assumptions.

>I'm sure relativity doesn't need to explain these, or anything.
Correct. Most of those are not even related to GR (comets, the corona, star formation). The one about colliding galaxies having the different redshifts has been prove false. You're talking about the claims by Arp, who handpicked a few galaxies that he thought were interacting. That's not good science. A much better test is to take many thousands of galaxies and search for correlations between different redshifts. These tests found nothing.
