In a 2013 paper, Freeman Dyson presented thought experiments challenging the detectability of gravitons via LIGO interferometry and via the Gertsheshtein effect. Dyson assumed a distance of several light years would be required for detection of the interaction between gravitational waves (GWs) and tenuous B fields and photons, making gravitons experimentally undectable. In this paper, we present contrary theoretical evidence for detectability of near-field interaction of gravitons, photons, and a magnetic field. Our first example of 100% probability of the Gertshenshtein effect working is due to a GW generated by a tokamak with a interaction of GW, B field, and photons, in a volume on the order of a few cubic meters. The 100% probability of the Gertshenshtein effect working leads to gravitons interacting with a strong uniform magnetic field, resulting in photons which are detected by appropriate instrumentation. In addition, we will also comment upon another issue, that of relic GW, as may be generated by a new uncertainty principle as elucidated by the author. And how that effects relic considerations as to inflaton physics. I.e. the frequency range of the early universe GW (gravitons?) and those of gravitons (GW) produced by the Tokamak may be one and the same i.e. very pronounced overlap. And we explain why.
