Summary
| Description |
English: Lightcone RL (orange), Hubbleradius RH (blue), Eventhorizon RE (violet) & Particlehorizon RP (green) in a flat universe (Ωr+Ωm+ΩΛ=1, Ωk=0). Initial parameters at a=1: Ωr=0.000092136, Ωm=0.315, ΩΛ=1-Ωr-Ωm, H0=67.15 km/Mpc/s (Ωr includes photons and neutrinos). Coordinates: comoving distances R by cosmic time t (x=R, y=t). The lightcone origin is at the present time t=13.842 Gyr at Scalefactor a=1. The big bang is at the bottom of the vertical t axis. For the animation click here.
