Brief and simplified suggestion to strengthen the efforts https://www.epistemologyontologyfoundationinstitute.org/philosophy-and-science-beyond-the-macro-world/quantum-gravity-could-soon-be-tested-using-ultracold-atoms. And to complement all related explorations as well as epistemoly and ontology quest.
The efforts are essential for empirical data. And should be applauded and supported . However, the answer is already known or should be obvious based on life and evolution process. Another way of saying is by analyzing the evolution process of life and existence or All That Exist and Ever Exist: from simple wave mechanics to spectra-field to quanta to atoms to molecules to RNA-DNA to organelles to cells to multi-cells to organism to primitive life to primitive intelligent life to primitive conscious life to primitive aware life ... and so on over aeons or from spectra-field world to quantum world to micro world to macro world. A simple way of saying is from simplicity to complexity. And beyond. And therefore, gravity existed since the creation of life and existence. And simple way of defining gravity is emergence or the interaction of parts of sum of parts of the greater whole (https://www.epistemologyontologyfoundationinstitute.org/nature-decode/march-04th-2021). The macro world does not just suddenly exist.
Analyzing life and existence evolution process would help with give answers, hints, insights, and solutions to many mysteries of life and existence. And therefore, proper concepts and methods can be derived as well as safeguarding against oversights and proper scientific path or quest. Thus, would greatly advance and accelerate the scientific and technological transformation as well as civilization and human species as a whole. And epistemology and ontology quest. And common and greater good in the known physical world. And beyond.
