Is Gravity of Quantum Force a Working Theory?

The idea of starting with like is gravity of quantum force has inspired a whole bunch of interesting experiments or interesting ideas about how that could work. People thought for a while that that was not a question we could answer first. Now instead, they're saying, well, let's figure that out first. And oh, actually, it might be possible to figure that out experimentally in the next few years and then use that at the core of our theory.
