Detection of Gravitons by Measuring Excess of Photon Luminosities from Interstellar and Intergalactic Hydrogen

George Savvidy, Pavlos Savvidis

Absorption of gravitons by interstellar hydrogen produces a measurable excess in photon luminosity that would indicate their presence.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The absorption rate of gravitons by hydrogen atoms is much higher than emission and proportional to the number of atoms and graviton luminosity, leading to a measurable excess in the photon luminosity ratio from interstellar hydrogen that would indicate gravitons.

C2weakest assumption

That the graviton-induced excess in photon emission can be cleanly separated from other astrophysical processes and that the graviton luminosity from stellar cores is sufficient to produce a detectable signal in interstellar hydrogen.

C3one line summary

Gravitons absorbed by interstellar hydrogen atoms produce a detectable excess in the ratio of photon luminosities, indicating graviton presence.
