Distances:

(See More Detailed List of Detailed Distances below)
(Longest distances and earliest times below are somewhat off: they are calculated from redshift using Hubble's Law with a Lorentz-factor correction and estimated Hubble Constant 70 km/Mpc, but with no accommodation for Λ or the universe's density. The age of the universe is currently cited as 13.82 billion years. )
