SUMMARY
The discussion centers on the theoretical possibility that certain electromagnetic (EM) fields can exhibit the same energy-momentum tensor (EMT) as gravitational waves. This hypothesis raises significant implications regarding the detection of gravitons, suggesting that if true, it may be impossible to detect individual gravitons. The conversation also touches on the adequacy of the EMT as a comparative tool for EM and gravitational radiation, particularly in relation to observed irregularities in the Cosmic Microwave Background (CMB) at low frequencies. Freeman Dyson's paper is referenced, which questions the feasibility of detecting individual gravitons.
