TOPIC: The Effects of Inertial Forces on the Dynamics of Disk Galaxies [refresh]

Tomer Zimmerman & Roy Gomel of Tel Aviv University alerted me to their preprint arguing that that phenomena of dark matter (on galactic scales) could be attributed to Inertial forces.

From their abstract:

*When dealing with galactic dynamics, or more specifically, with galactic rotation curves, one basic assumption is always taken: the frame of reference relative to which the rotational velocities are given is assumed to be inertial. In other words, fictitious forces are assumed to vanish relative to the observational frame of a given galaxy. It might be interesting, however, to explore the outcomes of dropping that assumption; that is, to search for signatures of non-inertial behavior in the observed data. In this work, we show that the very discrepancy in galaxy rotation curves could be attributed to non-inertial effects. We derive a model for spiral galaxies that takes into account the possible influence of fictitious forces and find that the additional terms in the new model, due to fictitious forces, closely resemble dark halo profiles. Following this result, we apply the new model to a wide sample of galaxies, spanning a large range of luminosities and radii. It turns out that the new model accurately reproduces the structures of the rotation curves and provides very good fittings to the data.*

From their abstract:

Thank you very much Zeeya!

Hi , thanks for sharing your work, it is a good idea, we need to know more about this DM, since the works of Zwicky, we search answers, we need to explain this big mystere inside the sciences community, many considered that it comes from white dwarfs or neutrons stars, BHs but there is a problem , it is not sufficient. Others have tried to modify the newtonian mechanics to explain this problem of...

All is a question of direct detection , it seems unfortunally not detectable and this detection needs to see the collisions between the inertial mass of two systems without for me the necessity to modify the newtonian mechanics, the problem is really that this matter does not interact with our ordinary but if my reasoning is correct, this matter is also in our actual standard model and probably in this quantum gravitation and also in the antiparticles, because the cold dark matter balance, now of course, we need to analyse for the detections a different logic superimposed to our stabdard model. There is something to analyse about the inertial mass of two systems but it is different and without modifying this newtonian mechanics. The gravitational mass so becomes the secret and if my reasoning is correct, so the quantum gravitation has something to do with this. See the freefall effect maybe to see better the gravitational mass, the aim is not to unify this GR and this QM but all in fact, the DE, the DM, the GR and the QM, the problem is really to consider only the photons like primordial essence and this GR. That implies that the gravitational forces, the internail forces, tha gravitationa, mass, the inertial mass can be unified simply in a pure newtonian logic of freefall. This spacetime is more than we can imagine, we have 3 aetehrs and not only one with this GR.

see also that if my reasoning is correct about the theory of spherisation and the 3D quantum and cosmological spheres in an universal 3D sphere in evolution, see that the spherical expansions and systems can be relevant to see the effects and distributions of matters.

What I tell in resume is that for a good explaination of the cosmologicalzation and so the spherisation, we need to consider this DE and this DM more the ordinary matter in superimposing the 3 aethers , see the relevance of the anti gravitational push spherical for this DE permitting to explain this evolution spherisation balancing the two other matters belanced themselves with the cold and heat , the series finite of quantum spheres become relevant considering 3 main series , and this serie has the same number than our cosmological finite serie of 3D spheres, oddly I have calculated it approachs the dirac large number.
