So, to clarify, gravitational radiation is conveyed and is also entirely "composed' of distortions in space-time ?
We don't need or expect an actual particle for this ?
And a follow up, this gravitational energy is radiating away from the merger site, and is being subsumed into the existing universal flux of gravitational energy, and that is mostly a relic of the formation of the universe when literally the entire mass of the universe was rending space-time in the same way, just at a larger and more violent scale.
And, the LIGO devices only see (to borrow a term from electricity) the AC component of the flux, the 'DC' component of the universal background radiation is unknown in magnitude, and it's 'density' (terminology?) is steadily decreasing in proportion to expanding volume of the universe ? And do we know the average 'density' of that DC flux, and if not, could it be large enough to be (pick one) dark matter, dark energy, 'sumtin else', or E. all of the above ?

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
