SUMMARY

Dragan Hajdukovic's models for dark matter are regarded with skepticism within the scientific community, primarily due to the prevailing consensus that only weakly-interacting particles with non-zero mass and low temperature can adequately explain dark matter phenomena. The discussion highlights the challenges of fitting non-particle dark matter models to observations of galaxies, galaxy clusters, and the Cosmic Microwave Background (CMB). A critical factor for evaluating Hajdukovic's models is whether he has estimated a CMB temperature power spectrum, as the absence of this would undermine the credibility of his theories.

PREREQUISITES
  • Understanding of dark matter theories and models
  • Familiarity with the Cosmic Microwave Background (CMB) and its significance
  • Knowledge of galaxy formation and clustering observations
  • Basic grasp of theoretical physics and model validation
NEXT STEPS
  • Research the Cosmic Microwave Background (CMB) temperature power spectrum analysis
  • Explore existing dark matter models, focusing on weakly-interacting massive particles (WIMPs)
  • Investigate the implications of non-particle dark matter theories
  • Review Dragan Hajdukovic's published papers for detailed insights into his models
USEFUL FOR

Astronomers, theoretical physicists, and researchers interested in dark matter theories and their implications for cosmology.

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?
 
Space news on Phys.org
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.
