AI Thread Summary
Dragan Hajdukovic's models on dark matter are under scrutiny regarding their acceptance in the scientific community. The consensus is that non-particle dark matter models face significant challenges in fitting observations of galaxies, galaxy clusters, and the Cosmic Microwave Background (CMB). The CMB is crucial for validating any dark matter model, and without Hajdukovic estimating a CMB temperature power spectrum, his model lacks credibility. While Hajdukovic is regarded as a competent theorist, the diversity of theoretical ideas often leads to many being proven incorrect. Overall, skepticism remains about the viability of his models in the context of established dark matter theories.

Hi, I have been reading a number of papers by Dragan Hajdukovic's on his work related to models for dark matter. How mainstream / well regarded is his work / models?

In general it is considered highly unlikely that any non-particle dark matter model is going to work (that is, anything but a weakly-interacting particle with non-zero mass and low temperature). It's really, really difficult for anything but a dark matter model to fit observations of galaxies, galaxy clusters, and the CMB together. The CMB is especially important here.

Has Hajdukovic estimated a CMB temperature power spectrum for his model? If he hasn't, I wouldn't give the model any credence at all.

Edit: I should add that I see no reason (yet) to believe that he's anything but a good theorist. It's just that there's a diversity of theoretical ideas, and most turn out to be incorrect.
 
Understood, and thanks, Chalnoth.
 
Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
