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: comoving 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. The comoving Particle horizon at the Big Crunch is twice the Antipode distance (the light emitted at the Big Bang makes a full roundtrip through the universe). |
