[non-baryonic] Dark matter is matter that does not interact with electromagnetic fields (light)...

IF it actually exists, it wouldn't interact with ANY form of electromagnetic radiation, not just the visible light portion of it. This would include: x-rays, gamma rays, ultra-violet, microwaves, etc, etc.

My point was that there is observational evidence for “dark matter”. Anyone who can come up with a better explanation for the observations should book their reservations for Stockholm.

Dark Matter is not like “global warming”, a politicized weakly validated theory, rather it is a placeholder until a more comprehensive theory is conceived. If that ever happens.
