This is what I find interesting. Assuming two quantum particles exert forces on each other. Now they both have mass but the forces they exert on each other are so much more powerful that the gravitational force would be impossible to experiment. Sort of like a man at a distance exerting gravitational force on the Milky Way with instruments the size of galaxy clusters to measure that man or force. Beyond mathematics there would be no experimental way. But my question is if mathematics itself says quantum particles do not have gravity or is that just a limitation of current understanding.

Limit of current understanding. everything at this level is a theory, with math to boot.. most theories say particles have mass and therefore interact via gravity at insanely small levels (which we cannot currently measure), and other fringe theories postulate particles don’t interact via gravity at all... we won’t be able to experiment with these theories until sensor tech / approaches like the OP are refined enough to be in the ballpark of detecting these small levels of interaction.

> But my question is if mathematics itself says quantum particles do not have gravity or is that just a limitation of current understanding. The maths of QM (Schrodinger equation, standard model) currently say that particles don't have gravity. But, they also imply that nothing has gravity - gravity doesn't exist at all according to the standard model. Obviously this is wrong, so we are searching for a theory of Quantum Gravity. There are various pieces of math that do have gravity and are consistent with standard QM, but each of them has various other problems, so none is universally accepted, and they vary significantly in how they add gravity to the standard model.
