Another observations Criteria?

Hi, ...If we can accept that Astronomy is open to different
Observations Criteria, in exploring the Space...may I propose another
one? Of course I' m not an Astronomer...but I think that perhaps we
can search in the Sky something different...Why not gravitational
Vectors?..I would like to give some Criteria to test it.. I have some
possible points, or lines in the Sky to verify an hypothesis. Thanks
to any answer!
Alexis.
