Do you know Dragan Hajdukovic's models work?

In summary, there is skepticism surrounding Dragan Hajdukovic's work and models regarding dark matter. It is generally believed that only dark matter models are able to accurately explain observations of galaxies, galaxy clusters, and the CMB. The CMB is particularly crucial in this regard. Additionally, there is doubt about the credibility of Hajdukovic's model due to the lack of a estimated CMB temperature power spectrum. However, it is acknowledged that Hajdukovic is a skilled theorist, but there is a history of theoretical ideas being proven incorrect.

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.
 

FAQ: Do you know Dragan Hajdukovic's models work?

What is the purpose of Dragan Hajdukovic's models?

The purpose of Dragan Hajdukovic's models is to explain the fundamental laws of physics and provide a new understanding of the universe.

How do Dragan Hajdukovic's models work?

Dragan Hajdukovic's models are based on the idea that the universe is filled with a substance called dark matter that interacts with ordinary matter through a fifth force. This fifth force is responsible for the expansion of the universe and can also explain other phenomena, such as the rotation curves of galaxies.

What evidence supports Dragan Hajdukovic's models?

Dragan Hajdukovic's models have been supported by various observations, such as the accelerating expansion of the universe, the discrepancies in the rotation curves of galaxies, and the existence of dark matter. These models also make predictions that can be tested through experiments and observations.

What are the potential implications of Dragan Hajdukovic's models?

If Dragan Hajdukovic's models are proven to be accurate, they would significantly change our understanding of the universe and the laws of physics. It could also lead to new technologies and advancements in our understanding of dark matter and the fifth force.

What are some criticisms of Dragan Hajdukovic's models?

Some scientists have criticized Dragan Hajdukovic's models for lacking concrete evidence and not being able to explain certain phenomena, such as the origin of dark matter. There are also concerns about the complexity and validity of the fifth force proposed in these models.
