Detection of Gravitons: Graviton Absorption and Excess of Photon Luminosity from Interstellar Hydrogen

TL;DR

This paper analyzes graviton interactions with hydrogen atoms, highlighting the potential to detect gravitons through excess photon luminosity ratios caused by graviton absorption.

Contribution

It provides calculations of graviton absorption and emission rates for hydrogen and proposes a method to detect gravitons via photon luminosity measurements.

Findings

Absorption rate of gravitons is significantly higher than spontaneous emission rate.

The graviton luminosity of stars is linked to electron-proton scattering in ionized hydrogen.

Measuring photon luminosity ratios could reveal the presence of gravitons.

Abstract

We compute the graviton absorption and emission rates by hydrogen atoms in line with the results obtained by Weinberg, Gould, Dyson and other authors. The spontaneous emission of gravitons by the hydrogen atoms has a tiny undetectable rate, while the absorption rate of gravitons is much higher and is proportional to the number of hydrogen atoms and to the graviton luminosity. The graviton luminosity of Sun, or a typical star, is induced by the scattering of electrons and protons in a completely ionised hydrogen plasma at the core of the Sun and their energies are in the eV to keV range. We suggest measuring the excess in the ratio of the photon luminosities from interstellar hydrogen atoms that is induced due to the absorption of gravitons. The excess in the ratio of photon luminosities would indicate the presence of gravitons.
