摘要

描述	English: Lightcone RL (orange), Hubbleradius RH & Particlehorizon RP (green) in a flat matter dominated universe (Ωm=1, Ωk=0). The gray dashed lines are the worldlines of comoving galaxies. rP (R=r/a) recedes with 3c in this model. Coordinates: comoving distances R by conformal time η=RP/c (x=R, y=η). The big bang is at the bottom of the vertical η axis.
