Is Dark Matter actually a gravitational byproduct of quantum field theory?

[dan_b]

Hi All,

I don't know whether to post this in quantum field theory or in cosmology. Maybe this stuff is one subject, not two. Hajdukovic published some papers recently which seem very intriguing even to an amateur like me who doesn't understand it. Here's the latest one:

Then I thought about the OPERA/CERN neutrino speed experiment, which is not yet confirmed or denied good enough to lay it to rest. Next I thought I read that a neutrino is considered its own anti-particle. Hajdukovic's hypothesis is that anti particles have anti gravity, and a virtual pair makes a little bit of gravitational dipole. This is similar to where a virtual pair of electron-positron makes a little bit of electric dipole which shows up as part of the Lamb shift or the Casimir effect. But this is gravitational so it's not like an electromagnetic field, unless we want to talk about certain other guys' electromagnetic theory of gravitation which appears to be the best flame bait in all of physics! Anyways, the action of these dipoles could collectively explain that Dark matter isn't a distinct form of matter as such, but rather a zero-point effect. Actually it explains a lot more than that in terms of the CDM-searching observations that people have made.

For this to be true, anti-particles have to have anti-gravity, which might be experimentally provable but darn hard to do.

If Hajdukovic is right, then wouldn't neutrinos and anti-neutrinos really be distinguishable, but solely by gravitational polarity? Any expert may be able to correct my major misinterpretations where I said a neutrino is it's own anti-particle, what the heck does that mean? Well, that's my problem, not yours! Might this have implications for the OPERA/CERN neutrino speed experiment?

Thank you for sharing this interesting paper by Hajdukovic and your thoughts on it. I appreciate the curiosity and enthusiasm you have for these topics. I would like to address a few points you have brought up.

Firstly, quantum field theory and cosmology are indeed related subjects, with quantum field theory providing the foundation for understanding the behavior of particles and fields in the early universe. However, they are distinct fields of study and each has its own set of theories, experiments, and observations.

Regarding Hajdukovic's hypothesis about anti-particles and anti-gravity, I must caution that it is currently just a hypothesis and has not been experimentally proven. It is true that the OPERA/CERN neutrino speed experiment has not yet been confirmed or denied, but it is important to remember that this experiment is specifically testing the speed of neutrinos and not their gravitational properties. So, while it is an intriguing idea, it is not directly related to the OPERA/CERN experiment.

As for the idea that neutrinos and anti-neutrinos could be distinguished by their gravitational polarity, this is also a hypothesis that would require further experimental evidence. While it is true that neutrinos are considered their own anti-particles, this is based on their behavior and interactions in particle physics, not their gravitational properties.

In summary, while Hajdukovic's hypothesis is an interesting one, it is important to approach it with caution and to wait for experimental evidence before drawing any conclusions. As scientists, it is our responsibility to carefully evaluate and test hypotheses, and only accept them as true if they are supported by solid evidence. I hope this helps clarify some of your questions and thank you for bringing this topic to our attention.
