Summary
| Description |
English: Comoving worldlines (gray dashed), Lightcone rL (orange), Hubbleradius rH (blue), Particlehorizon rP (green) and Antipode rM (purple) in a closed universe (Ωm=2, Ωk=-1). Coordinates: proper distances r by cosmic time t (x=r, y=t). The Lightcone origin is at the turning point at Scalefactor a=2 and t=π/H0 when the Hubbleparameter H=0 and the universe is between expansion and contraction. The Big Bang is at the bottom and the Big Crunch at the top of the vertical t axis. |
