We know more than that:

  1. It has positive mass/energy.

  2. It is interacting gravitationally.

  3. It is not, at most barely, interacting electromagnetically.

If not (1) and (2), we could not observe its effects on spacetime curvature 
as if baryonic matter would be there; if not (3), we could observe it 
directly.

The “From” header field values of your postings are lacking a real name.
