It was recently detected an unidentified emission line in the stacked X-ray spectrum of galaxy clusters. Since this line is not catalogued as being the emission of a known chemical element, several hypotheses have been proposed, for example that it is of a known chemical element but with an emissivity of 10 or 20 times the expected theoretical value. Here we show that there is a divergence in the Stefan-Boltzmann equation at high energy density conditions. This divergence is related to the correlation between gravitational mass and inertial mass, and it can explain the increment in the observed emissivity.
