Ok to begin I will begin by talking briefly about my discussions with my Quantum Mechanics (specializes in Particle physics) professor and my Cosmology Professor (who studies particle physics with respect to cosmology).
The question I asked my professors is since virtual article in the electromagnetism interactions are electron-positron pairs and they have a mass. Provided we have a sensitive enough experiment in principle.
Taking into account the expected mass of something like the sun and even calculate the mass that escapes in the form of energy we should expect it to either be constant or a small decay. This would cause the gravity measurements to either be constant of the force to weaken overtime.
What we should not expect is these to be a small sinusoidal oscillations in the gravity that correspond to the frequency at which the electron-positron pairs pop in and out. And if we get these corresponding oscillations then what we a measuring is the the virtual particles adding small mass then disappearing and repeating this cycle.
My Quantum Mechanics professor says since at the end of the Feynman diagrams energy is conserved we should not see any perturbed mass sinusoidal oscillations.
My Cosmology Professor says it may be possible.
My questions is who is more correct in this regard is my experiment possible Provided it is sensitive enough?
Thanks by the way I have only learned Quantum Mechanics so far including perturbation theory, spin, position and momentum space transforms. Please when you reply try explain while taking into account my understanding.
update note- I am talking about the Quantum fluctuations caused by the Lamb Shift in which the electron-positron pairs appear and disappear. This would cause gravity fluctuations with the same frequency as the Quantum fluctuations caused by the Lamb Shift
