cosmological distance
(appreciable distance across the universe)
The term cosmological distance generally means a distance
covering a substantial part of the observable universe, such
as a gigaparsec or more. The term suggests sufficient distance
that there are differences in the universe (e.g., regarding
star formation and galaxy formation), that observing
over the distance is affected by redshift and
cosmological time dilation, and potentially by curvature
and a varying Hubble parameter, and limits the usable methods
for studying astronomical objects such as galaxies.
The specific term cosmological distance ladder refers to the
combination of distance measurement techniques used to
measure cosmological distances.
