New Map of Dark Matter Spanning 10 Million Galaxies Hints at a Flaw in Our Physics

They’ve theorized those black holes existed at the center for long before they detected them, and that doesn’t really fix the problem. In fact, since black holes are massive, they would only make the center spin faster, which makes the discrepancy that much worse.

The problem is that the outer arms of the galaxy are spinning too fast, not that the center is spinning too slowly.

I think the flaw in the Standard Model will have to do with the effect on gravity on light.  The problem is manifest in two galaxies that are connected to each other, while one of them has a red shift indicating it is far, far behind the other and could not possibly be connected.

Halton Arp will be vindicated.

I think the flaw in the Standard Model will have to do with the effect on gravity on light.

We tend to think of light as a straight line affair and measure distance accordingly, but if light is being bent hither and yon by every celestial body somewhat between the source and the observer, it's actually traveling a greater distance. Like driving a car on a curvy road - traveling 20 miles to get 10 miles as the crow flies. Does that differential result in a red shift? I dunno. Crows are crafty.

If find this to be fascinating.

Redshift quantization, also referred to as redshift periodicity,[1] redshift discretization,[2] preferred redshifts[3] and redshift-magnitude bands,[4][5] is the hypothesis that the redshifts of cosmologically distant objects (in particular galaxies and quasars) tend to cluster around multiples of some particular value.
...
Ruling out errors in measurement or analysis, quantized redshift of cosmological objects would either indicate that they are physically arranged in a quantized pattern around the Earth, or that there is an unknown mechanism for redshift unrelated to cosmic expansion, referred to as “intrinsic redshift” or “non-cosmological redshift”.

Except we still have never actually seen these alleged black holes and black holes don’t solve the galaxy rotation problem. It’s theoretical construct piled on theoretical construct, a series of fudges to explain why the theory doesn’t fit the observations.

At what point is it permissible to admit that the theory is just plain wrong?

[stremba]

No. The fact that galaxies rotate is thus explained, but the sped at which stars revoke about the central black hole can’t be explained by Newtonian gravity or GR. Basically, the speed depends on the mass of the central body. The reverse is true; knowing the orbital speed allows calculation of the central mass, assuming the orbital distance is known. The mass calculated this way should be independent of which orbiting body is used. For galaxies this is not the case. Stars further out orbit faster than predicted. This is only possible if there is unaccounted for mass or GR is wrong. Hence either dark matter or MOND. Dark matter works better in cases other than galactic rotation, so that’s the accepted explanation.

[Magnum44]

I get what you are saying, but I think you are describing two body dynamics, which work for the Earth orbiting the sun or a satellite orbiting a planet. I wonder if in the case of stars on the edge of a galaxy orbiting the galaxy, you have to take the sum of all the stars inside that orbit and include it in GM. In other words its a multi-billion body problem and the dynamics are much more complicated.

Thanks BenLurkin. Already posted, but hell, who can tell anyway? ;^)

You’ve come to the same conclusion I have. With string theory and all of the extra dimensions involved other complete University could be stacked upon ours like some fourth dimensional book. It would explain why gravity is so weak with it reaching across more dimensions than light does.
