Do what??? I don't even understand the question! Um...No?

All comments and thoughts are appreciated on this site, but please make them make sense

I'm confused on how you're using the term "relativistic" here. From what I could find, the physics definition is "accurately described only by the theory of relativity" and the doctrine of relativism is "There is no universal, objective truth according to relativism; rather each point of view has its own truth". So, I guess I really don't get your question....

Dr. Michael Baker and Prof. Joachim Kopp demonstrate that the universe may have gone through a phase during which the stable dark matter symmetry principle was broken, making it possible for the hypothetical dark matter particle to decay.

During the electroweak phase transition, the symmetry that stabilizes dark matter would have been re-established, enabling it to continue to exist in the universe to the present day.

The new mechanism they propose may be connected with the apparent imbalance between matter and antimatter in the cosmos and could leave an imprint which would be detected in future experiments on gravitational waves. They hope to find proof of their new principle at CERN's LHC particle accelerator and other experimental facilities.

By what mechanism could a neutron star be dispersed into a powder?

Not enough of it to fill space. There are other interesting theories, though.
