  Our Gedanken experiment is a thought experiment as to what is called gravo-electric and gravo- magnetic potentials linked to gravo-electric and gravo-magnetic fields. We examine what Padma- nabhan presented in an exercise as of a linkage of electromagnetic fields with Gravitation. The modifications we bring up take the nonrelativistic approximation as the beginning of an order of magnitude estimate as to gravitons, generated electromagnetic fields, and are by definition linked to the total angular momentum of an initial configuration of “particles” of space-time import. The innovation put into Padmanbhan’/s calculation is to for total mass M, used, to substitute in M ~ N(gravitons) times m(g), where m(g) is about 10^?62 grams, as well as specify distances, for the object spinning as being about Planck length in size, give or take a few orders of magnitude. The results are by definition very crude, and do not take into account relativistic effects, but are pro- bably within an order of magnitude important comparison. We conclude with an a comment as to the possibility of an additional polarization as due to a response function of an interferometer to “scalar” polarization as maybe indicate a scalar-tensor gravitational theory as a replacement for General Relativity.
