What about is there or is there not a particle associated with the
gravity field?
Photons (virtual) are associated with the E/M field. Gravitons
(virtual) are associated with the quantized gravity field.

Here's an interesting paper. I don't understand a lot of it, but I
think it means that there can be no global reference frame in which the
same particles exist, i.e. Unruh radiation will necessarily exist in
some frames and not others. Maybe LC can explain it to me.
/*Gravity: We might have been getting it wrong this whole time*/
/To try to understand gravity on the quantum level, Hirosi Ooguri, the
director of the Kavli Institute for the Physics and Mathematics of the
Universe in Tokyo, and Daniel Harlow, an assistant professor at the
Massachusetts Institute of Technology, started with the holographic
principle. This principle explains three-dimensional phenomena
influenced by gravity on a two-dimensional flat space that is not
influenced by gravity. This is not a real representation of our
universe, but it is close enough to help researchers study its basic
aspects.//

//The pair then showed how quantum error correcting codes, which explain
how three-dimensional gravitational phenomena pop out from two
dimensions, like holograms, are not compatible with any symmetry;
meaning such symmetry cannot be possible in quantum gravity./
