Note that this says nothing about the viability of WIMPs as dark matter.
It could be that they neither annihilate nor decay.


OK, they do not travel at high speeds, wimps go leisurely around,
and the interaction between them and this universe is highly difficult,
possible only in some specialized environment: living beings.

Since this invisible matter is heavier than our matter, it can
gravitationally influence a solution, guiding slowly dissolved
components into more concentrated areas.

If that kind of matter can control its density, it can acquire any
gravitational field it wants, what allows it in principle, to guide
atoms to specific places, where prepared reactions take place.

A black hole the size of an atom, made of that kind of matter can guide
accurately an atom to any place it wants.

Using just CO2, some solution containing enough raw materials, it can
start a self-sustaining living thing in a new planet.

Those kind of interactions of dark matter with normal matter are
maybe more interesting than just looking for a simple cross-section
annihilation reaction.

In any case it is a good sci-fi start isn't it?

Because we are just like a group of blind people extending their arms
and trying to figure out an elephant.

That matter must be HERE.

But where?
