Summary

Description
English: Milne model in FLRW coordinates. Hubble radius RH: blue, light cone RL: orange, hypersurface of constant t (red) and T (pink). Comoving distances R by conformal time η=RL/c (x=R, y=η). The particle horizon is infinite in proper and comoving coordinates, but cT in Minkowski coordinates. Doublechecked with Figure 1 in DOI:10.48550/arXiv.2005.01968
