If Dark Matter exist; Type of interactions with matter.

[alpha2cen]

If Dark Matter exist, many types of interactions might appear.

The interactions with neutron star, quark star and Black Hole may be especially high?

They have very compact structure. So, no particles can not penetrate into them easily.

If we did not find any interactions from these objects, could we have confidence with Dark Matter existence?

This is a kind of neutron star radiation.

The shape of the bright spot is strange, neutron star is surrounded by something.

 

Why this pulsar make a tail in the empty space?

If there were no interactions between Black Hole and Dark Matter, surrounding Black Hole would be empty?

This is a model of interaction between matter and Dark Matter.

We do not know size and density of Dark Matter.

However, we can imagine the interaction style.

Blue spheres are nuclei.

If we would give photon any non-0 mass there would be no need to search for Dark Matter and Dark Energy..

This Figure represents a geometric model of the collision of Dark Matter with matter on their detection.

Without any collision, we can not expect any interacting phenomena about Dark Matter .

Collison is a minimal condition.
