Summary

Description
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 cosmic time t (x=R, y=t). The big bang is at the bottom of the vertical t axis.
