Interesting to view this article after the recent press blitz about the galaxy collision "finding" of dark matter.

I wonder if we should expect the dark matter involved in the galaxy cluster collision to be something like neutrinos. Theoretically, heavier particles would not spread so far between galaxies.

The cold component of dark matter can be created simply by more dense vacuum, aka Aether. Try to imagine the vacuum is compressible and elastic and it collapses under action of normal matter into more dense blob.

The warm component of dark matter can be create simply by heavily ionized atom nuclei with the electromagnetic component of interaction. Such atom nuclei cannot be detected by the light in visible spectrum and gravitomagnetic interaction can be significant here.

Rydberg hydrogen? That would be interesting.

Maybe even single protons or alpha particles or even heavier atom nuclei. Such particle can be detected just in X-ray specters, 'cause they don't absorb/emit no visible light, having no free electrons.
