Summary
| Description |
English: R(t), R(a) & R(η) diagrams as polar φ(я) projections. Comoving worldlines (gray dashed), Lightcone RL (orange), Hubbleradius RH (blue), Particlehorizon RP (green) and Antipode RM (purple) in a closed universe (Ωr=2, Ωk=-1). Coordinates: comoving distances R by cosmic time t (φ=R, я=t,a,η). The Lightcone origin is at the turning point at Scalefactor a=√2 and t=√2/H0 when the Hubbleparameter H=0 and the universe is between expansion and contraction. The Big Bang is at the center of the diagram. |
