Wavelength-Independent Extinction in the Milky Way, Is it new physics?

摘要: The paper Baruch (2025a) shows that there is an apparent wavelength-independent extinction coefficient of 0.06 magnitudes per kiloparsec across the Milky Way. Baruch 2025b) shows that the Hubble constant values of Riess et al (2016, 2018a and 2018b), Freedman et al (2019) and the Planck satellite (Ade et al 2014) coincide if the extinction coefficient is a function of the density of dark matter. This wavelength-independent extinction has a frequency threshold between 160Ghz and 300 Thz. This paper seeks a possible process by which dark matter can absorb light.

The current data on dark matter is reviewed to determine how dark matter could act as a wavelength-independent absorber of light in the visible frequencies. The discussion of the role of inertia and momentum in general relativity and its relationship with the other forces since the Einstein paper on General Relativity of 1915 is reviewed. It is conjectured that for a pair of gravitationally bound dark matter particles a photon with sufficient momentum would effectively “ionise” the pair, releasing the two dark matter particles, and absorbing the photon. The approximate mass of the dark matter particle is derived. It is suggested that this dark matter extinction provides real data to help settle the role of inertia and momentum in General Relativity. A test for the “ionisation” process is suggested.
